Webpoints in a volume the rendered part of the object or scene, also known as view volume. For square images, given the PyTorch3D convention, (+1, +1, znear) is the top left near corner, and (-1, -1, zfar) is the bottom right far corner of the volume. The transformation from view –> NDC happens after applying the camera projection matrix (P) if ... WebThe perspective projection describes perspective viewing of the scene. Points in the scene are projected onto a viewing plane perpendicular to the z axis. The Perspective () function computes this transformation; it takes a field-of-view angle in fov and the distances to a near z plane and a far z plane.
