Reflection about a Line - 2-D and 3-D Transformations
Reflection is a transformation that produces the mirror image of an object. Since we discussed that the mirror reflection assists in achieving 8-way symmetry for the circle to make simpler the scan conversion process. For reflection we require to know the reference axis or reference plane depending upon where the object is2/3-D.
Suppose the line L be shown by y=mx+c, here 'm' is the slope along w.r.t. the x axis, and 'c' is the intercept on y-axis, as demonstrated in Figure. Assume that P'(x',y') be the mirror reflection regarding the line L of point P(x,y).
What is orthographic oblique projection? When the direction of the projection is not normal (not perpendicular) to the view plane then the projection is called as oblique proj

How to implement z-buffer algorithm using C programming
Acquire the perspective transformation onto z = - 2 Plane, where (0, 0, 18) is the center of projection. Solution: Now centre of projection, C (a, b, c) = (0, 0, 18) ∴ (n 1
