3D animation – the genesis
In this entry, we want to allow you a little look behind the scenes.
A 3D animation shows the movement of a freely generated object in a virtual three-dimensional space.
In particular, the abstract models, technical constructs or virtual characters also extinct animals and fantasy creatures, which with the conventional means is impossible to show or to explain, for many people can be visualized with the aid of computer animation. Another advantage of the three-dimensional models towards photography or recorded film, is that then an object can be viewed from another angle at any time and through thus the spatial imagination of the viewer complex subjects easily understandable..
3D computer graphics consists of two major milestones:
One is the interactive or real-time 3D computer animation, and the second consists of pixels which are formed as individual graphics or pictures or issued as a film.
Usage of the rendered 3D animation.
By contrast the interactive approach for this kind of 3D computer animation, the ambient light, materials, shadows, etc. will rendered in the final image. Thus, we have a still image with 3D objects that can no longer be rotated. The image consists of pixels and can only be adjusted with image-editing program. Extended possibility it’s a movie. As our eye recognize about 24 images per second as a flowing movement, the movements of the 3D model in 25 or 30 individual frames per second can be rendered and summarized in a video file for viewing.
What can be done with 3D computer animation, you can admire in numerous films. Rendered 3D computer animation allows the artificial beings and even people on the screen to bring to life.
As with the interactive method rendered 3D animation can be used for many areas. For example, for presentation of your product, for film and advertising, cartoons, technical visualizations, architectural visualization, character design, medicine, trade fair and much more.
The advantages of a rendered 3D animation are photorealistic image with great demands on reality.
Usage of interactive 3D animation.
To show interactive 3D environment is an extra program “engine” used in which the ambient light, camera control and the user commands will be calculated. The interactive 3D computer animation allow users to interact with an animation. This is the case when the user can change movement by a touch screen, or a special key, on the keyboard, or by the gamepad.
An illustrative example is the games. But even with a product presentation, or interactive tour with an architectural visualization, while planning the exhibition stand, in the medical field or training processes will the interactive 3D computer animation used.
They’re getting more and more areas, where the interactive 3D animation, be made into an exciting experience.
This is understandable, because in interactive 3D animation the viewer with a presence effect can free to decide, how he will moves around the object or through the virtual building.
How to make a 3D Animation?
Steps to arrive at a finished 3D animation..
Step 1. Design.
First, will be the idea for an 3D animation as is possible defined and collected as a drawing or sketch.
Step 2. Modeling.
Modeling of 3D models. By modeling process the topology is important, so that the model is suitable for error-free and smooth bends in the following 3D computer animation.
Step 3. Texturing.
Texturing of 3D objects. Here the 3D model gets colors, textures and surfaces structure.
Step 4. Rigging for 3D animation.
Rigging. In order to animate the models, they should get the handles and a scaffold that can store animation. Through the connection between objects and invisible framework, the movement is transferred to the models.
Step 5. Movement (3D animation)
In the step, the finished models or frameworks (handles) are added to a motion. The poses of objects or virtual characters are stored using a timeline..
Step 6. Setting the scene.
Setting the scene. There will be put the camera and lights. Through numerous settings will be set the mood of the scene. The scene gets the global illumination and the 3D objects get your materials with appropriate properties.
Step 7. Rendering.
Rendering. The final image is calculated. For an 3D animation are created in required resolution 25 frames per second. For fine tuning the picture is divided in many layers as specular, reflection, glossiness, etc.
Step 8. Postprocessing.
Assembling all layers in an image. Picture settings. For a final 3D computer animation, from rendered images will a film created.
Making Of, a Bruce Lee 3D portrait
Have a look at this video. In the film you can vividly see how arises a Virtual character.
Of course, the work process is accelerated several times in the film and takes much more work time. The emergence of a 3D animation is a very complex process in which are many ways and tools that should the animator choose correctly. This requires a lot of experiments and samples to carry out to find a proper method for creation of a Photorealistic model. The film shows only already proven approaches.
