Opengl rotate

Web9 de jul. de 2024 · Solution 1. You need to multiply your Model matrix. Because that is where model position, scaling and rotation should be (that's why it's called the model matrix). Note that to convert from degrees to radians, use glm::radians (degrees) That takes the Model matrix and applies rotation on top of all the operations that are already in there. Web2 de jan. de 2024 · OpenGL enables the programmer to perform three basic ModelView transformations or combinations thereof on the ModelView matrix, rotation, translation (movement in a straight line through space), and scale (changing the size of an object in each of the three dimensions independently).
