Clipping and 3D Primitives
This unit introduces you to three important concepts of Computer Graphics. After that discusses the concept of clipping, which means removal of objects not in the window frame to be plotted on a display device. This simple concept has far reaching consequences in computer animation and especially in video games which is a fast growing industry. Good clipping strategy is critically important for speeding up the rendering of the current scene and hence plays a crucial role in maximizing game's performance and visual quality.
1. What do you understood by the term graphic primitives? Ans. Graphic primitives are the basic graphic objects that can be united in any number and method to produce a new i
Derive the common transformation for parallel projection into a specified view plane, here the direction of projection d=aI+bJ+cK is along the normal N=n1I+n2J+n3K along with the r
To prove ‾P (1) = p n Solution : since in the above case we determine each term excluding B n,n (u) will have numerous of (1 - u) i (i = 0 to n) consequently by using u = 1
What is reflection? The reflection is actually the transformation that produces a mirror image of an object. For this use some angles and lines of reflection.
Diffuse Reflection - Polygon Rendering & Ray Tracing Methods It is characteristic of light reflected from a non-shiny, dull surface. Objects illuminated solely through diff
Ray Tracing - Polygon Rendering and Ray Tracing Methods Basically Ray tracing is an exercise that is performed to attain the realism in a scene. In easy way Ray Tracing is a w
Unrepresentative vertex normals - Modeling and Rendering Calculated vertex normals may not adequately present the surface's geometry. For illustration, if we calculate vertex
Light Sources - polygon rendering and ray tracing methods Light Sources are key parts in any ray traced scene, since without them; there would be no rays to trace. Light sour
