I want to set the “camera” of opengl, the GL_PROJECTION_MATRIX, just the same way as my real camera is viewing the scene. I use gluperspective to set the internal parameters, and discovered already the meaning of this and the way to set it explicitely.
But then is the translation and rotation. I know those transformation according to the main axis, and to set a model on a position it is then first setting the translation with gltranslate and then multiply this with the rotation matrix. But what do I have to do to set the GL_PROJECTION coorect? does the rotation has to come before the translation, or is an inverse, transpose of the matrix necessary.
