The object in right of the image is a mesh of smooth triangles. As you notice, there are two clear artifacts in the image. The sphere has a straight shadow line which seems unnatural and the mesh has a non-straight shadow line ...
WebWith perspective projection, a line looks like a point on the screen if and only if it passes through the eye position. Since you revert modelview matrix to identity, the eye is located at the origin (according to this question).Pass (0, 0, 0) as one of the vertices, and hopefully you'll see that line degenerates into a point.

WebRay Tracing. Rendering software such a POV-Ray creates an image using a technique known as a ray tracing which broadly means it takes a description of geometry (which includes surface materials and light sources), a model of a virtual camera, and a projection plane made up of the pixels in the final image. It then creates what the camera would ... thor and the dark worldWebBy default POV-Ray calculates the amount of light that reaches a surface from an area light by shooting a test ray at every point light within the array.
