WebIn the last post we went over how to do 3D but that 3D didn't have any perspective. It was using what's called an "orthographic" view which has its uses but it's generally not what people want when they say "3D". Instead we need to add perspective. Just what is perspective? It's basically the feature that things that are further away appear ... Web20 de jul. de 2024 · When switching from ortho to perspective, glm calls glm::radians(fov) for its parameter and you switch zNear > 0.0f and zFar > zNear. Your parameter for aspect ratio might be off also due to the final result not being float. Also, OpenGL uses the glm::orthoLH and glm::perspectiveLH prototypes, which are default.
