Scene layout setup

Scene setup involves arranging virtual objects, lights, cameras and other entities on a scene which will later be used to produce a still image or an animation. If used for animation, this phase usually makes use of a technique called key framing, which facilitates creation of complicated movement in the scene. With the aid of key framing, instead of having to fix an object's position, rotation, or scaling for each frame in an animation, one needs only to set up some key frames between which states in every frame are interpolated.

Tessellation and meshes

The process of transforming representations of objects, such as the middle point coordinate of a sphere and a point on its circumference into a polygon representation of a sphere, is called tessellation. This step is used in polygon-based rendering, where objects are broken down from abstract representations ("primitives") such as spheres, cones etc, too so-called meshes, which are nets of interconnected triangles. Meshes of triangles (instead of e.g. squares) are popular as they have proven to be easy to render using scalene rendering Polygon representations are not used in all rendering techniques, and in these cases the tessellation step is not included in the transition from abstract representation to rendered scene.

3D animation Rendering:

Rendering is the final process of creating the actual 3D image or animation from the prepared scene. This can be compared to take a photo or filming the scene after the setup is finished in real life.
Rendering for interactive media, such as games and simulations, is calculated and displayed in real time, at rates of approximately 20 to 120 frames per second. Animations for non-interactive media, such as video and film, are rendered much more slowly. Non-real time rendering enables the leveraging of limited processing power in order to obtain higher image quality. Rendering times for individual frames may vary from a few seconds to an hour or more for complex scenes. Rendered frames are stored on a hard disk, then possibly transferred to other media such as motion picture film or optical disk. These frames are then displayed sequentially at high frame rates, typically 24, 25, or 30 frames per second, to achieve the illusion of movement.

3D graphics APIs:

3D graphics have become so popular, particularly in computer games, that specialized APIs (application programmer interfaces) have been created to ease the processes in all stages of computer graphics generation. These APIs have also proved vital to computer graphics hardware manufacturers, as they provide a way for programmers to access the hardware in an abstract way, while still taking advantage of the special hardware of this-or-that graphics card.

These APIs for 3D animation computer graphics are particularly popular:

1. OpenGL and the OpenGL Shading Language
2. OpenGL ES 3D API for embedded devices
3. Direct3D (a subset of DirectX)
4. Render Man
5. Render Ware
6. Glide API
7. True Dimension LC Glasses and 3D monitor API
What is logo designing?

A logo design is a graphical representation of your company's identity. It is composed of a symbol, illustration, or typography (sometimes called a “logotype”) Purpose of logo designing

1. Attract attention, and then leave an impression
2. Create a look that is unique and distinguishable
3. Reflect the overall image of the company it represents
4. Promote a sense of authenticity and professionalism
5. Promote your brand image
