I have two problems, the first is, that I’am a beginner in OpenGL and I have to learn it for my diploma thesis as physicist!
My tasks are to improve a programm, written in C++ and OpenGL, that reads measured data and simulate a watersurface of this data. The program also use the glut-library to create a window.
The problem is, that I have to implement a possibility to write each frame of the animation in an bmp- or tiff-… file, so one can build a avi or something else of this images with a suitable other program!
My question is: is there anybody who can tell me a way to solve this problem or can give me information that can be useful for me, to write each rendered image of my glutwindow into an bitmap-file for example.
Sorry for my bad english and thanks for any help!
