Ray tracing perspective projection

To get the gist of perspective projection consider the following image: Given the Point P(px,py,pz) what is are the coordinates of the projected point P′(px′,py′,pz′)? If d=1 then the problem simplifies to just dividing by the z-coordinate.And this is what the whole magic about perspective projection is all about.It is just … See more What is the field of view here (FOV)? 90°. Why? Consider the following sketch: Assuming that d=1 and the horizontal field of view is hFOV2from trigonometry we know: What should we do if we want to have a different FOV? … See more In 3D computer graphics when talking about perspective projection we have often the concept of a near-and a far clipping plane.Thereby n is the distance of the near clipping to … See more Task 1: Given: n=10, f=100 and fov=90° Question 1.1:How does the perspective projection matrix with a non-linear z-buffer depth value distribution look like?
