Area-Subdivision method
This method is a type of an image-space method although uses object-space operations re-ordering or sorting of surfaces as per to depth. Area sub-division method takes advantage of area-coherence in a scene via locating those view areas which represent part of a particular surface. In Area-sub-division method we successively subdivide the whole viewing as screen area, frequently a rectangular window, in small rectangles till each minute area is the projection of part of a particular visible surface or no surface at all.
Use DDA algorithm to get the output of your program as shown in Figure ANs: Use DDA( ) function to plot line segments that have end points on diametrically opposite points

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:
What is orthographic parallel projection? When the direction of the projection is normal (perpendicular) to the view plane then the projection is called as orthographic paral
What is surface patch? A single surface element can be explained as the surface traced out as two parameters (u, v) take all possible values between 0 and 1 in a two-parameter
Implement Cohen Sutherland and Liang Barsky line clipping algorithms in C-language. Test your code for line segments with end points falling in various regions.
Potentially entering and leaving points - P E and P L The intersection point of the line and window might be classified either like potentially leaving or entering. Before g
Orientation Dependence - Modeling and Rendering The outcomes of interpolated-shading models are dependent of the projected polygon's orientation. Because values are interpolat
A color histogram is a representation of the distribution of colors in an image. For digital images, a color histogram represents the number of pixels that have colors in each of a
