Discuss in detail about rendering
Computer animation uses a technique termed as avars (animation variable) where starting point is generally a series of stick figures; for example Toy Story used over 700 avars(1 avar = position of every feature e.g. mouth). Successive sets of avars control all movement of animated character. Once stick model is moving in required way, avars are incorporated into full wire frame models. Ultimately, surfaces are added requiring a process known as rendering (i.e. turned into a realistic image).
Problem with Interpolated Shading There are several more shading models that intermediate in complication among Gouraud and Phong shading, linking the liner interpolation of t
Common Principles of Ray Tracing Based upon the nature or attributes of the surface given by the user, the subsequent effects are implemented, as per to rules of optics: a
Perspective Projection 1. Perspective projection gives more realistic appearance and uses the same principle as used in camera. 2. Perspective projection is not an affine tr
Hardware For Computer Animation It comes in many shapes, sizes and abilities. Much hardware is specialized to do only specific tasks. Other types of hardware do a variety of t
Consider the line segment AB in 3-Dimentional parallel to the z-axis along with end points A (- 5,4,2) and also B (5,-6,18). Carry out a perspective projection upon the X=0 plane;
Digital Video: Digital video is a form of video recording system which works through using a digital, quite than analog, representation of the video signal. It generic means,
Buffer Areas Required For Z-Buffer Algorithm For applying z-buffer algorithm, we need two buffer areas or two 2-Dimentional arrays: 1) Depth-buffer [i,j], to sa
What is Polygon mesh? Polygon mesh is a method to show the polygon, when the object surfaces are tiled, it is more convenient to state the surface facets with a mesh function.
B-spline curves are piecewise smooth polynomial curves. B-spline curves are defined over an interval which has been partitioned into sub-intervals. On each subinterval B-sp
