Orthographic Errors #18
Description
Hi, I'm trying to do some tests using an orthographic matrix, but I seem to be getting some errors in the ray intersection. I don't know if I've set something up wrong.
eye := ln.Vector{-3, 4, 3} // camera position
center := ln.Vector{0, 0, 0} // camera looks at
up := ln.Vector{0, 1, 0} // up direction
znear := 0.1 // near z plane
zfar := 10.0 // far z plane
step := 0.01 // how finely to chop the paths for visibility testing
matrix := ln.LookAt(eye, center, up).Orthographic(-1, 1, -1, 1, znear, zfar)
paths := scene.RenderWithMatrix(matrix, eye, width, height, step)
As you can see, edges are clipped before they go behind objects.
