How to calculate the inverse of a 4*4 opengl transform matrix

WebFor the purposes of this tutorial, I'm going to try to avoid picking a coordinate system, so that it will be equally useful for both OpenGL and DirectX programmers. We'll call the rotation matrix for the X axis matRotationX, the rotation matrix for the Y axis matRotationY, and the rotation matrix for the Z axis matRotationZ. WebOpenGL fixed pipeline provides 4 different types of matrices (GL_MODELVIEW, GL_PROJECTION, GL_TEXTURE and GL_COLOR) and transformation routines for these matrices; glLoadIdentity(), glTranslatef(), glRotatef(), glScalef(), glMultMatrixf(), glFrustum()and glOrtho().
