The fact that the camera moves and the projection matrix can either provide orthographic or perspective projections. The model matrix will describe translation, rotation, and other affine transformations for the model inside the world. A typical use case is to pass theĬlassical transformation matrices like model, view, and projection.įor the sake of simplicity, we only pass an identity matrix for each of the uniforms to the shaders, which will result in no transformation at all. These values are called uniforms and they are sent from the host during the render loop. Sometimes we need data that does not change during a draw call, i.e., all the vertices and fragments need to receive the same data. 1 if ( ! gladLoadGLLoader ( reinterpret_cast ( glfwGetProcAddress ))) 2 Ĭode listing 11: minimal fragment shader Uniforms
