Engine 3D Model Tips

3D models of engines are very detailed and to model them requires knowledge of their major components, functions, and classification. Below find the fundamentals of identifying internal combustion engines and how this can help you quickly model or search for stock 3d models.

Engine 3D Models are graphical representations of internal combustion engines. They are comprised of several parts including cylinders, pistons, crankshafts, and camshafts.

Engine 3D Model Configuration

The first step in modeling or searching for stock 3d models of engines is to determine the engine configuration and its use. The layout of the major components which include the cylinders, pistons, crankshafts and camshafts, determine the configuration of the engine.

Engines are typically classified according to their piston motion (single, inline, radial, piston-less), placement of their valves or the placement of their camshafts. A common classification of engines includes the four stroke engine, two stroke engine, piston-less rotary engine (Wankel), gas turbines, and jet engines.

Major Components of the Engine

After you have determined your engine configuration, the next step is to locate the major components on engine diagrams, photographs, digital images or still renders of 3d models. The location of the major components is mostly determined by the shape of the combined engine block and crankcase. Therefore, the location of the major components of the engine and its shape can help you search for and identify the type of engine you are looking for.

For example, when looking for a four-stroke engine, first identify the major components such as the crankshaft, connecting rod, camshafts, and the valves. Then, you can look for other components such as the piston, crank pin, and cylinders with spark plugs (on gasoline engines only). However, if you are looking for a two-stroke engine, look for an exhaust outlet and fuel inlet instead of looking for the valves.

Other engine components that can help you identify engines are the cooling, lubricating, engine control (startup), and exhaust systems.

The exhaust system is made up of devices that improve the efficiency of the engine and also control chemical and noise pollution.

For example, the exhaust system can quickly help you find a jet engine. This is because jet engines generate thrust via their exhaust system. Their exhaust has the shape of a high velocity nozzle which can be easily identified and compared to other engines when you browse through still renders of an engine 3d model.

Cooling systems can also help you identify certain types of engines. The cooling systems are typically made of components that use air or liquid to reduce high temperatures. Combustion generates a great deal of heat, and some of this heat transfers to the walls of the engine. If the engine overheats, then failure will occur because the engine will physically fail or the lubricants will degrade to the point that they will no longer be able to effectively protect the engine.

For example, the cooling system of rocket engines is different than that of automobile engines because they use the fuel to cool. Other high altitude engines use controlled and gradual loss of material to cool engine components.

Engine control systems can also help you discern engines. The components that make up the engine control enable the start and shutdown of the engine and control of the power, speed, torque, pollution, combustion temperature, efficiency. Many control systems today are digital, such as the on-board diagnostics, which are used to perform electronic diagnosis of a vehicle and tuning of the engine.

Understanding the major components and engine classification can greatly help you cut down time when looking for an engine 3d model or when you are modeling engines.

3D Hand Models – Modeling Approaches

3D hand models are modeled using several techniques and the best approach that you can use for your project will greatly depend on the end use of the 3d model.

3D Hand Model

Modeling of the 3d hand models takes great attention to detail as the hands are one of the most complex body parts. The hands can dramatically change shape with each posture and can perform a wide range of complex movements in a short time.

3d models that are used for still renders tend to be less complex than the ones used in animations or for virtual worlds. The 3d hand models used for animations typically need a specific range of motion.

However, the ones used for virtual worlds are used to interact with the 3D world and a wide range of motion is needed. Also, a more personalized and realistic look is often desired. Therefore, different approaches should be used for modeling for still renders, animations, and virtual worlds.

Using proportions can give you less complex models that can be used for still renders and presentations. However, this approach may not be desirable when looking for very realistic and personalized human hands. See examples of stock 3d hand models.

The first approach is to use the proportions of the human body to size the hand. The length of the hand (from the wrist to the middle finger) should be roughly the length of the inner forearm. The male hands should be longer and wider than female hands. The hand of an adult male is about 189mm long and about 84mm wide, while the female hand is 172mm long and about 74mm wide. Also, the fingers should not be perfectly straight, instead they should have a tendency to curve slightly towards the middle finger.

The second approach is to use approximation to establish the right proportions. When using approximation techniques, the proportions are estimated using the existing features of the hand anatomy. For example, the creases of the palm, hand contours, and the wrinkles on the back of the finger knuckles typically mark the areas where the skin is attached to the tendon beneath the skin.

Other techniques involve generating a series of hand postures from real human hands, which yield hand movements and gestures that are very realistic. For this technique the hand 3d models are made up of both a dynamic and a surface model. The dynamic model is used to generate the hand postures. The surface model is based on 3D shape of a real human hand. This surface model is used to generate the hand shape based on the posture obtained from the dynamic model.

Motion capture and analysis is used to capture and process the hand movements. This can yield very realistic and accurate movements of the human hand. For example, for an animation of a hand making a fist, the 3d hand model fingers would need to curl in a spiral and not a circle. To achieve this, the movement of the joints of a real human (and their relative position in space) would be captured and recorded. Then this recorded movement would be assigned to the fingers so that they curl in a spiral making a fist.

Regardless of the approach you use, modeling of the human hand is complex and requires great attention to the shape, gestures, and movement of the hand.

How to Use Interior 3D Model Scenes To Build Your Own Designs

Interior 3d models help your clients visualize the final interior design of a house, building, or facility. However, you can also use them as a starting point or guideline for new projects because they contain many 3d objects that can be used to form your own theme or style. Below find more about interior 3d scenes and ways that you can use them for your 3d projects.

Interior scenes come in a variety of design styles and are used by many interior designers and architects to help their clients visualize the look and feel of the design.

An interior 3d model or scene is usually made up of a group of 3d objects and is typically rendered with powerful 3d software and/or plugins to make it look very realistic. Typically, when the interior scene has been rendered, the materials for each object and the lighting setup is included with the 3d model.

Each 3d model or object in the interior scene plays a role in the design. This is important to keep in mind when you are using them as a starting point for your own design. When you clearly understand the role of each object, you will be able to mix and match and build your own interior designs.

A typical 3d interior scene contains several architectural 3d models that make up the scene, including the room structure, lights, furniture, kitchen cabinets and utensils, electronics, accessories, etc. Therefore, when you start the 3d modeling process for interiors, it is recommended that you understand the role that each element will play in the overall design. Also, keep in mind what the clients are most interested in visualizing so that you can satisfy their needs.

When you begin designing the interior, select a theme or style and use this style or “idea” throughout a room. When you keep this interior style consistently throughout the room, you will give it a feeling of completeness and put your clients at ease. Also, the elements of the house or building interior must contribute to the function and form of your design.

Also, you can use other existing styles for your interiors. Designers often start with existing styles and build on them. Some of the most popular interior styles include: Louis XV and Louis XVI, Victorian, Islamic, Feng Shui, International, Mid-Century Modern, Minimalist, English Georgian, Gothic, Indian Mughal, Art Deco, etc.

Top 5 Tips for Meeting your 3D Modeling and Rendering Deadlines

Modeling of People requires great attention to detail and significant amount of time. Ensure you that you meet your deadlines when modeling people 3d models, by communicating clearly with your clients and setting expectations.

Modeling of People requires great attention to detail and significant amount of time. You can avoid missing your deadline by communicating clearly with your clients, setting expectations, and cutting down time and costs by using stock 3d models of people and characters.

In today’s fast paced environment we all know that it is very important to meet your 3D project deadlines. However, clients are demanding more for less and technology is constantly changing the game, so what can we do to ensure that we and our team meet our deadlines without burning midnight oil or sacrificing our weekends? Below find some tips that can help you and your team avoid missing your deadlines and be more productive.

Make sure that your team knows why meeting your deadline on time every time is important.

Discuss with your team and clients the link between the speed to finish the 3D modeling project versus the profit/rewards. Also share these rewards with your team.
Also, show the urgency to finish ahead of time by taking the necessary actions and making smart decisions. Therefore, when the team needs a decision from you, don’t sit on that decision!

Get involved early in the 3D modeling process.

Getting involved early allows you and your team to better understand the needs upfront, plan and adapt to the changing needs of the project. Also, you will be able to influence the direction and the outcome much easier than if you try to make changes later.

Delegate the necessary authority to your team early so you can get faster decision making.

After setting clear goals, move quickly to execution. If you are managing a 3D team, then step out of the way and let your team make faster decisions. Also, allow them to take responsibility for finishing on time.

Maintain constant communication with your clients and your team.

Your presence and constant communication will send strong and positive signals to your clients and your team.

You don’t need to spend too much time, what is important is the frequency of your communication and meetings. This will allow you to be informed about the progress and detect problems when they are small and easy to solve.

Develop relationships with your suppliers of 3D and related services.

Start developing these relationships early, as this will make it easier for you and your team to work together and successfully outsource your 3D needs. When you spend time building these relationships, you will have time to know their capabilities and they will have time to understand what you are looking for.

For example, don’t wait until the day before your deadline to start outsourcing your 3D modeling as it will not only cost you more but also there might not be enough time to communicate or render the 3d model exactly how you want it.

Also, having a relationship with your suppliers of 3D and related services can save you time, especially when you are looking for stock 3D Models or requesting custom 3D.

Flat Pyramid 3D Model Marketplace provides stock 3D Models and custom 3d modeling and rendering services by highly qualified artists that can deliver high quality 3D custom work at affordable rates.

Know when to outsource your 3D Modeling and Rendering

Imagine that your pitch was successful and now your clients want your animation in a futuristic city scene. You are an expert in animation…but not in 3d modeling and cities are known to take weeks to do!

The animation you used for the pitch took you 2 weeks and they now want a more complicated one in a week…HALF THE TIME AND MORE TO DO.

You could customize a stock 3d city scene to look futuristic or outsource it. This project has a tight deadline and you are not an expert in customizing 3d city models fast…and outsourcing could allow you to focus on the animation.

Sound familiar? Outsourcing 3d modeling and rendering or doing it in-house is a common dilemma 3D artists and animation studios face, especially when rushing to get 3d projects done.

When it is a good time to outsource your 3d?  A rule of thumb from one of our clients is that

“If someone can make it in half the time I can…then its time to hand it off. My time is just too valuable.”

Typically, clients outsource 3d modeling and rendering when the 3d model, such as a 3d city scene, can be done or customized much more efficiently by custom 3D services such as Flat Pyramid Custom 3D.

What could take weeks to do can take expert 3d modelers that specialize in 3d cities just days. So you get less frustration, quicker turn around, and higher quality results, which are worth spending money on.

Below are tips to help you know when outsourcing can work for you:

  • You run into something you don’t really well and it is not part of your core skills. Also it will take time to learn it and become efficient at it.
  • You have too many 3D projects stuck in the pipeline and budget constraints prevent you from taking on more 3d artists on staff.
  • The 3D projects go in cycles, sometimes you need more people, sometimes less, and you want to avoid downsizing.
  • The 3D project is a one-time project.
  • You need to reduce costs to be able to be more competitive when you are bidding for 3D projects.
  • It is more productive and profitable for you to let expert custom 3D services handle it.

Also, when you outsource 3d modeling you increase your profits, since you save more than half of the 3D project costs mainly because you save in labor costs. Outsourcing experts agree that having someone else do the areas that are not your expertise enables you to do more and you can leverage lower labor costs and increase your profit.

Realize you can’t do it all and you must find ways to speed up your 3d development cycle and get 3d projects to your clients quicker and cheaper than the competition – or face losing clients.

When you have decided that its best for you to outsource, consider using the expertise of Flat Pyramid artists with a wide range of experience in custom 3D modeling and Rendering, see more custom 3d tips.

Buy Face 3D Models or get them made to your specifications with our custom 3d service.

In many cases, the attractiveness of the 3d face models is a big requirement as beautiful people do “attract” our attention more than unattractive people.

So how do you adjust a 3d human face so that it’s beautiful?

There are certain characteristics that make people beautiful, like certain shape of the eyes, full lips, high cheekbones, etc.  First start by adjusting the 3d face model so that it follows the general human proportions.  Then, you further adjust the 3d face model using the list of characteristics below to give your 3d model a beautiful human face.

What makes the human face beautiful to someone is not universal, the culture and time in history also matters. However, as an overall guideline, beautiful faces are always very symmetrical and look healthy.

Below find what you can do to adjust your 3d human faces to make them more attractive.

How To Make Female 3d Face Models More Attractive

3D modeling and animation of people and characters requires specialized skills and knowledge. Below find some tips that can help you create and/or get human 3d models that look realistic and have right human proportion.

3d character models require great attention to detail to achieve the right proportions, locomotion, and facial expressions that will allow the human model to convey human emotions, speech, and movement.

Buy Human Characters 3D Models or get them made to your specifications with our custom 3d service.

3D Modelers that specialize in 3d human models analyze human proportion to create an accurate representation of the figure and movement of the human body. They also take into consideration the color of human hair and skin. Human skin has a wide range of hues including very dark brown up to very pale pink. Human hair color is typically blond, brown, red, black, and gray.

3D Modeling of the Human Body

3d modeling the human body requires attention to detail to achieve the right proportion. The average height of an adult human is 1.5 to 1.8 m (5 to 6 feet) tall. To achieve a very realistic looking and accurate model of the human male or female, 3d modelers use heads instead of meters or inches as follows:

3d Woman Female Realistic Model

3d Woman Female Realistic Model

  • The human figure is an average of 7 to 7 1/2 heads high(including the head).
  • Width from shoulder to shoulder: 3 heads wide
  • Distance from top of head to the bottom of chest: 2 heads
  • Distance from wrist to the end of fingers of the hand: 1 head
  • Distance from elbow to the end of fingers: 2 heads
  • Distance from hip to the toes: 4 heads
  • Length from top to bottom of buttocks: 1 head

Human body types vary substantially and depending on the type of human 3d model, these proportions are adjusted by the 3d modelers and refined by animators.

For example, ideal 3d female models with long legs and arms are typically 8 heads tall. Male hero 3d models have big chests and long legs and are typically 8 1/2 heads tall.

3D Modelers and Animators also analyze human movement in order to prepare the 3d human model for further processing including rigging and animation.

3D Face Models

3D face models of humans are animated using the lips, brows, and frown lines to create human expressions that convey certain emotions. The audio is synchronized with the mouth, eyes and brows.

To convey the right emotions, animators analyze the human body’s structures and movements. They also study facial expressions and human emotions.

The human emotions are typically captured and reproduced using the expressive face of a 3d model.

3d modeling the human faces also requires great attention to detail to achieve the right proportion.

Below are some typical proportions that 3d modelers use to create 3d face models. When the 3d face model needs to be attractive, special characteristics common to beautiful people should be used, see how to make 3d face models beautiful and attractive.

  • The eyes are halfway between the top of the head and chin.
  • The bottom of the nose is halfway between the eyes and chin.
  • The mouth is halfway between the nose and chin.
  • The corners of the mouth line up with the centers of the eyes.
  • The top of ears line up above the eyes, on the eyebrows.
  • The bottom of ears line up with the bottom of the nose.
  • Eyes are typically centered halfway between the top of the head and the chin.

Before starting the process of 3D Modeling of the human body, keep in mind that it requires the expertise of highly qualified artists that specialize in this area. A good alternative is to buy high quality 3d human models in stock which also cut downs your 3d modeling costs.
