Tips and Tricks for Creating Textures From Photos

By:  Elizabeth Gallagher
TRU Graphic Solutions Ltd

T
here are plenty of tutorials and articles on the internet covering the subject of general photography and a hand full on the subject of texture photography, so rather than going over old ground, I would like to share a few personal tricks and tips I have developed when taking photographs for purpose of texture creation.

Equipment

With the acceleration of technology and the current economic climate, now is a good time to purchase your first digital camera and gain some control over your creative destiny by taking your own photos.

These days, you can purchase a 10 Mega Pixel digital camera for around $200 – $300 and this is perfectly adequate for the creation of textures. But just like any hobby or creative pursuit, there is always a learning curve. Expect to make mistakes, learn from them and know even the most seasoned photographer has to go through some post correction process before his/her photos are suitable for the purpose of texture creation.

Sun and Shadow

For the same reason the sun works well for Sun Dials, it can often work against the process and purpose of texture photography. Bright sunny days are perhaps ironically conditions to avoid when taking photographs for texture creation. The sun casts shadows on just about every type of surface and even small shadows can make a photograph very difficult to work with when attempting to create a seamless texture later.

This is a bad image to create a texture because it has shadows.

Additionally, shadows on game textures will be in conflict with many game engines that use Dynamic Lighting to simulate natural weather and light environments. When shadows and light move in “real time” within a game scene, static shadows displayed on game textures will look “out of synch” or artificial, even to the untrained eye.

For example, compare the two window photo textures. The  photograph to the left ( the window with the arches and shadows) demonstrates perfectly the negative impact that shadows have on architectural photography. As you can probably see, it would be practically impossible to fix or use this photo for any type of digital artwork.

Now compare with the photograph below, which was taken on a typical overcast day in December. Notice that there are no visible shadows at all and this would be a perfect candidate for the creation of a good game texture.

So, for the purpose of texture photography, overcast or cloudy days offer the best lighting conditions for texture photography, as shadows are subdued and subtle.

This is a very good image to create a texture because it does not have shadows.

Missed Opportunities

I cannot tell you how many times I have driven past a fantastic opportunity for texture photography and I didn’t have my camera with me. It’s the most frustrating feeling and once in desperation, I tried to use my phone camera, which perhaps inevitably, resulted in a waste of time and effort.

After doing this several times I decided to leave my camera in the boot of my car along with a fully charged battery so now if I see an interesting building on my travels, I am good to go.

Try and get into the habit of taking your camera with you wherever you go, even if it’s just a trip to the shopping mall.

The environment we live and work in is ever changing and opportunities may pop up one day and disappear the next. This is especially true with old historical buildings that are being demolished and replaced by new and quite often uninspiring and clinical looking architecture.

More Is More

What may appear like a perfect shot from within your camera LCD screen can sometimes prove to be less than perfect when finally viewed in full resolution on your PC monitor.

There is nothing more disappointing than realizing your “perfect photo” is actually out of focus or over/under exposed when opened up in your Photo editor. Whilst these imperfections can sometimes be fixed, it’s always better to get the shot right in the first place.

To reduce the chances of this happening I take 3 or 4 shots of the same subject therefore increasing my chances of obtaining at least one good quality photograph that requires little to no post correction editing.

Move Closer

When I first stated taking photos for texture creation I would only see the obvious. The front of an ornamental building, the Baroque window on the face of a castle wall, or the beautiful stone relief work on a church building.

Eventually I discovered that if I looked “beyond the obvious” I was able to get about 20 more textures from the same object.

Whilst building and architecture may have initially caught my eye, I began to notice areas in more detail and discover the beauty in age and imperfection. The rotten wood in a window frame, the corroded decay on the surface of a metal industrial container, cracks and exposed brickwork in a plaster wall all have potential for fantastic grunge textures.

Learn to see beyond the obvious. There are often two very different types of textures you can shoot from the same subject, the architecture on the whole and the surface material it’s actually made up of.

About Architectural Rendering – CAD

You more than likely have heard about CAD rendering, and even if you are not a graphics designer you may very well not know just how frequently or where it can be used. You might be surprised just how often and in what applications CAD rendering appears.

Architectural rendering is not just for architects in spite of its name. Automobile manufacturers, landscapers, engineers among others make use of CAD rendering or have it completed for them. It allows them to discover imperfections appearing in design and perspective well before costly setbacks are made in real-time production.

Architectural rendering is extremely detailed oriented and includes realistic lighting style as well as textures to convey a much more natural look and feel to the modeled object.  A virtual walk-through can be created for the web to give prospective buyers an authentic feel for the design. Car designers are giving life to their models in 3D just before production using architectural rendering.

CAD, or computer aided design, could be as easy as the 2D representation with minor detail or realism to being complex and flexible as 3D parametric solid modeling. It is dependent upon the use the end product may be put to, along with the competency of the CAD operator. The easiest are 2D or wire models.

There are numerous manufacturers of CAD software programs readily available. These products range in pricing from freeware (big learning curves with low-end simplified outcomes), all the way to higher priced applications with state-of-the-art engines which can actually take a design from the drawing board and give it life. Although, even the high-priced software programs may additionally have higher learning curves because of the alternate options and details which can be imported.

Should you be a designer you might not necessarily be considered a software genius. CAD software takes quite a bit of skill and usually either schooling or hours upon hours of trial and error. Architectural rendering or CAD may be outsourced and quite often this is actually the wisest choice concerning time and cost.

Should the possibility of a rendering service appeal to your situation as well as to your finances, then it is essential that you look at examples of their work, ask about their delivery time, along with balance costs. Make sure you pick a reliable service and be mindful of just about any that will promise too low a price or even only offer stock rendering. Superb services get as much details that they can before presenting a price. Be wary of any that offer a custom architectural rendering service for a flat fee or the prices appear to be way too low. When it comes to architectural rendering, just like most things, you typically get what you purchase.

Should you decide to figure out how to use Architectural rendering software then set aside sufficient time due to the learning curve. Take time into discovering tutorials which may shorten the studying time. You should make sure your software program is useful considering the use you would like to put it through and remain patient.

Do Not Use Custom 3D Rendering Services If You Have A Stock 3D Model That Meets Your Needs

When you get your 3d animations done by dependable custom 3d rendering services you save on 3d modeling costs. Due to the nature and popularity of 3d models, the need for high quality 3d will continue to grow in the coming years. Also, 3d models are used in many fields, including interactive media that ranges from videos, architectural renders, 3d animations, simulations and anywhere you want to virtually represent an object and then manipulate it via software. It is important to note that 3d rendering is achieved with the use of commercial 3d software. The type of software that is used greatly depends on the application that will be displaying the 3d model and also on its end use.

There are several techniques that custom 3d rendering services use when rendering a character or creating still renders. One way is to include as many details as possible so that the 3d model looks sharp and like a real model. Another approach is to create enough detail to get the basic shape of the 3d model. The first approach gets a high poly model while the second approach gets a low poly 3d model.

Rendering Services

To start rendering, the artist sets up the various inputs and textures in the 3d software programs and plugins. Then, after checking all the parameters, the application runs to complete the rendering. This process takes a lot of cpu time. This means that if a mistake is made, then process has to start all over again.

Use a 3d rendering service if you are a newbie in 3d. This gives you the advantage of being able to tap into the knowledge and experience of highly skilled artists at any time. Keep in mind that the computer graphics field is constantly innovating and custom 3d modelers and rendering artists are always finding better ways to utilize 3d software and plugins to deliver results fast.
3D artists who want to specialize in rendering should spend the time learning these skills. Remember, if you are not going to be an active render artist professional, then it is best to employ your precious time doing what you are really passionate about, because the learning curve can be very steep. On the other h

and, if you are going to focus on this only and like rendering, then by all means take a learning course and study how best to deliver high quality results in a timely manner.
Another alternative is to speed up the process by buying 3d models that are very close to what you want. Then, these stock 3d models can be changed by 3d rendering services to your specifications. This cuts down costs and saves time because they are not they have a solid starting point so they can just focus on rendering it, thus it will be faster.

There are many tutorials available to learn software programs such as  blender and others. Some tutorials are available when you get this commercial software while others are made available or sold by a thriving community of expert artists. The most important thing to consider before getting courses is that one will not teach you everything you need to know. Rather, you need to start by getting building blocks of understanding and then progress slowly until you are able to take on the advanced tutorials and start getting highly detailed results.

Most of the time I hear that clients decide to outsource it to 3d rendering services when they can not afford extra staff, do not have the skills in-house, but need high quality 3d modeling and rendering results.

Your Own Custom 3D Models vs. 3D Modeling Services

Custom 3d models are in most cases not easy to make when you don’t possess the 3d skills and experience. You also have to be familiar with the required tools, including many 3d software programs and plugins and keep up with the trends in the 3d industry.

It requires great skill in part due to how 3d models are made, manipulated, and displayed. They are representations of objects in three dimensions into 2D renders or images. For this step you will need very good rendering skills that can get you renders of custom 3d model that are realistic looking and highly detailed.

These 3d models initially look like wire frames comprised of points and lines. The more detailed the denser the mesh. They are then

rendered via specific software and plugins  into 3d software file formats that can be used by graphic artists for a variety of projects including avatars and environments for real life worlds, in the health care fields, including models of internal organs, simulations, and of course print materials, tutorials, games engines, etc.

Generally those who enjoy artistic skills who enjoy a challenge stand a better chance at making professional 3D models. However, when used in business applications, advertising, or for the artist who favors to target the art not the software then making their own isn’t usually the best choice.

Your budget as well as the amount of time that you have available to complete the task can play a part in whether your team uses an existing and reliable 3d modeling service or invests time in learning this new skill. There are many benefits when you make your own custom 3d models because you get what you need; you imagine it and then create it.

There are additional considerations to take into account if your in-house artists make your own 3d models. The most important is that high quality 3D models are seldom produced rapidly. The second consideration is that 3d modeling and rendering services will generally offer quicker delivery time for custom 3d models because they have experienced 3d modelers and rendering artists that focus on just customizing models.

The return on the investment of your valuable time and money is the base line when examining various 3d modeling services. It is often the cost versus the time lost during production. Naturally, a business person, health care professional or advertising firm may not have.

Utilizing 3D modeling services is common for advertising firms that make ads for their clients, health professionals that want to sell their prescriptions to doctors, video productions and architectural designers. They outsource their 3d projects because of the ability to cut down costs and get it done fast. Making 3d models is routinely just too slow and occasionally too pricey compared to the cost of just getting custom 3d models done by experienced 3d modeling artists.

Artists who like new program interfaces should select their 3d modeling application conscientiously keeping a few things in mind like their abilities or inclination to even try to make their own 3d models. There are also other alternatives, such as some freeware applications available for anyone to start with relative low costs. However, depending on the open source community and your previous knowledge in 3d, this option might not give you the same results as the more commercial professional software. The best way is to start learning the basics and then progress into more advanced levels to gain a better understanding of the process and its potential.

The bottom line is that when you get your custom 3d models made by 3d modeling services you save time and money. However, before you go ahead and get these services, consider putting together a comprehensive list of the things you need. After all, the more time you put into making the decision to use the services and defining your requirements, the more satisfied you will be with the results that you will get.

Face 3d modeling is done using stock or custom 3d models that are created with smooth meshes and a lot of details. They can also be done using high end capturing devices and software to get a model that is then further processed using 3d modeling software. Here we discuss the first approach.

You can cut down time and production costs if you purchase a 3d model from a 3d marketplace to use in your face 3d modeling and animation. Using a ready made 3d model will help you a lot during your face 3d modeling process. However, remember that when you use one that has already been made, you will have to add your own features and you will have to change it so it can be unique.

To start, lets look at the help you get when using this approach to start the process. Custom 3d models allow for an easier way to obtain the right proportions for the 3d face and also the necessary details that are needed to ultimately meet your needs for the face 3d modeling project.

There are many advantages when you decide to use a customized 3d model especially when you start the face 3d modeling process. Essentially, by taking this step you can get the realistic location of the eyes, eyebrows, face, mouth and other proportions.

Let’s me illustrate this with an example. When you need the licensing rights for a character, you will most likely need to get custom 3d models of characters. You can opt for getting a high quality one that is already made that is also highly realistic and may even include the necessary rigging or facial movements.

Face 3D Modeling of a Woman

Bear in mind that to use the face 3d model or add a feature you will need to have specialized 3d modeling and rendering talents throughout the process of face 3d modeling in order for you to mesh it again and make it look like a human face. After all, a stock 3d model is not exclusive meaning you don’t own the rights. Therefore, it is not uncommon for you to have to alter it to meet your requirements or to make it a truly original face.

In addition, most face 3d modeling almost always involves further work particularly adding facial movements and emotions. In other words, most custom 3d models that involve any part of body need lots of additional manipulation to look real.

There are several methods you may use to create custom 3d models of human faces. If you are not an expert 3d modeler then it is best to get the services of one that specializes in this area. If you are familiar with the 3d process, try to get a starting model which will have the basic outline of the face, without all of the details. This starting model can be referenced from a photo, video, clay, drawing or even a stock 3d model. Face 3d modeling involves using the outline to build and modify the face so that it includes all the necessary details.

Often, the desired face is of an existing human, such as celebrity or political figure. When this is the case pictures or video can be used to aid in the creation of the basic shape and proportion of the face. Also these same picture or video can be analyzed to tweak the shapes and proportions of the face and to add the facial expressions. These facial expressions give any custom 3d model of the face a look that can be very realistic and almost as accurate as the existing human face. Then, the 3d modeler can use this realistic looking custom 3d model of the face and create stills or use it in animations, saving time and money during the 3d face modeling process.

For instance, as you go through the face 3d modeling process, you can expedite the process by capturing the human face using video. Then, you would use the location of the eye corners, nose tip and mouth corners together with specialized face recognition software to generate a highly realistic looking 3d face model. Then, you would use this output as the kick off point of your face 3d modeling and then you would add a range of poses, facial expressions and even additional features like audio and talking ability.

To achieve higher accuracy and a realistic human like appearance, you’ll need more facial points to go by and stronger equipment, which can become expensive. However, if you don’t have this available another cheaper way to realize a very human look is to manipulate the custom 3d models yourself or get 3d modeling and rendering services, like the services from Flat Pyramid,  to do this for you so that you can have input on how the finished face 3d model will looks throughout your face 3d modeling until you get the required look that you need.

Flat Pyramid is a 3d marketplace where you can buy 3d models, sell your 3d models or get custom 3d models made, including highly realistic face 3d modeling, 3d people, and characters.
