Opengl perspective projection
Web5 de fev. de 2024 · OpenGL wants to present to the programmer a right-handed coordinate system before projection and left-handed coordinate system after projection. That's the … WebA typical OpenGL projection matrix (e.g. glm::ortho, glm::perspective or glm::frustum) turns the right handed system to a left handed system and mirrors the Z-axis. That means, if you use a (typical) projection matrix (and no other transformations), then the vertex coordinates are equal to the view space coordinates.

The perspective projection matrix generates 4D homogeneous coordinates. You cannot use a 3x3 matrix and generate a 4D vector from it. Hi Alfonse Reinheart, Thanks for the reply.
