1. Modify the DDA algorithm for negative sloped lines; discuss both the cases i.e., slope > 1 and 0 < slope < 1.
Ans. For the generation of lines along with negative slopes as:
Slope < 1: successively raise y and respectively reduces x
Slope > 1: successively raise x and respectively reduces y
Aliter: This hint will use further.
As the shown above figure say L1 and L2 are lines along with -ive slope along with a magnitude of <1 and >1 respectively. So for the generation of that line, you may take reflection of the line regarding the concerned axis and obey the general algorithm of line generation. So then you may inverse reflection the transformation and this will offer you the line generation of -ive slope.
Traditional Animation techniques as: 1) Key Frames 2) Cel Animation Formula: Required Key frames for a film = {[Time(in seconds)]
Draw the five regular polyhedras using physics-based modeling method. Implement a fractal algorithm with possible personal extensions. Also, specify the extensions.
2. Describe how the Bresenham rasterisation algorithm is advantageous when compared to any other existing method.
Define the term Avatars- Animation Avatars are another instance of animation. These are frequently used to represent people either in 3-D (as used in computer games) and in 2-D
