Glfw orthographic projection
WebAn introduction to matrices. Simply put, a matrix is an array of numbers with a predefined number of rows and colums. For instance, a 2x3 matrix can look like this : In 3D graphics we will mostly use 4x4 matrices. They will allow us to transform our (x,y,z,w) vertices. WebExample 3: Orthographic Projection (OGL03Orthographic.cpp) As mentioned, OpenGL support two type of projections: perspective and orthographic. In orthographic projection, an object appears to be the same size regardless of the depth. Orthographic is a special case of perspective projection, where the camera is placed very far away.
