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).
What you mean by parallel projection? Parallel projection is one in which z coordinates is discarded and parallel lines from every vertex on the object are extended unless the
Important points for Bresenham Line Generation Algorithm Note: Bresenhams algorithm is generalised to lines along with arbitrary slopes with identifying the symmetry
what do you mean by high definition systems? Define aspect ratio? What is a refresh buffer? What is the difference between bitmap and pitman frame buffer? Explain the basic oper
Simulation: There are several things, places and events people cannot witness in first person. There are a lot of causes for this. Several may happen too rapidly, several may be t
what is fixed point scaling? how composit transformation techniques works on it
Algorithms for Basic Line Segment Plotting There are two important algorithms for basic line segment plotting-DDA algorithm and Bresenham algorithm. Both the algorithms use th
Can you list at least three important applications of computer graphics? There are lots of interesting applications of computer graphics. Three common applications are compute
1. Modify the DDA algorithm for negative sloped lines; discuss both the cases i.e., slope > 1 and 0 Ans. For the generation of lines along with negative slopes as:
Performing rotation about an Axis For performing rotation about an axis parallel to one of the coordinate axes (say z-axis), you first need to translate the axis (and hence the
What are the advantages of rendering by patch splitting? i. It is fast-especially on workstations with a hardware polygon-rendering pipeline. ii. Its speed can be varied b
