It was formed on 27 Feb with the goal of developing tools and recommended practice for the representation of geographical data using the Virtual Reality Modeling Language VRML.
Such images may be stored for viewing later or displayed in real-time. In computer graphics software, the distinction between 2D and 3D is occasionally blurred; 2D applications may use 3D techniques to achieve effects such as lighting, and 3D may use 2D rendering techniques.
Apart from the rendered graphic, the model is contained within the graphical data file. However, there are differences. A 3D model is the mathematical representation of any three-dimensional object. A model is not technically a graphic until it is displayed.
Due to 3D printing, 3D models are not confined to virtual space. A model can be displayed visually as a two-dimensional image through a process called 3D rendering, or used in non-graphical computer simulations and calculations.
History William Fetter was credited with coining the term computer graphics in  to describe his work at Boeing.
One of the first displays of computer animation was Futureworldwhich included an animation of a human face and a hand that had originally appeared in the experimental short A Computer Animated Hand, created by University of Utah students Edwin Catmull and Fred Parke.
Overview 3D computer graphics creation falls into three basic phases: The two most common sources of 3D models are those that an artist or engineer originates on the computer with some kind of 3D modeling tool, and models scanned into a computer from real-world objects.
Models can also be produced procedurally or via physical simulation. Basically, a 3D model is formed from points called vertices or vertexes that define the shape and form polygons. A polygon is an area formed from at least three vertexes a triangle.
A four-point polygon is a quad, and a polygon of more than four points is an n-gon. The overall integrity of the model and its suitability to use in animation depend on the structure of the polygons. This defines spatial relationships between objects, including location and size.
Animation refers to the temporal description of an object, i. Popular methods include keyframing, inverse kinematics, and motion capture.
These techniques are often used in combination. As with modeling, physical simulation also specifies motion. Rendering Rendering converts a model into an image either by simulating light transport to get photo-realistic images, or by applying some kind of style as in non-photorealistic rendering.
The two basic operations in realistic rendering are transport how much light gets from one place to another and scattering how surfaces interact with light. Altering the scene into a suitable form for rendering also involves 3D projection, which displays a three-dimensional image in two dimensions.

These communities allow for members to seek advice, post tutorials, provide product reviews or post examples of their own work.A good idea is to set the initial randomizer to a truly unique number like the current time in military format—a hour clock including hour (0 to 23), minute (0 to 59), second (0 to 59), and millisecond (0 .

It also includes the EAX library for realistic environment simulations and the so called World Definition System where you are able to define different areas with different environments and let the WDS handle occlusion and obstruction as well as blending different environments that a sound will pass in.
