WebOct 25, 2024 · Solved! Here's what I did: Changed glm::mat4 view = camera.GetViewMatrix(); -> glm::mat4 view(1.0f); For projection, I used glm::ortho() instead of glm::perspective() Web1 Answer. Sorted by: 16. For anyone interested in the issue, it was with: ortho = glm::ortho (0, width, height, 0, 0, 1000); Where the arguments are supplied as integers, not floats. Therefore the integer division applied within glm::ortho was creating an incorrect orthographic projection matrix. Share.
