Hi,

do you know an easy way to generate movies from OpenGL animation ?
Do you know where I could find examples ?

Thanks a lot

??? “OpenGL animation” ???
OpenGL doesn’t support any type of animations, it’s a low level API, you know.

You want to use animated textures?

Go to nehe.gamedev.net, there’s a tutorial on how to load an AVI format movie. Maybe it’ll help.

Hi,

in fact I do not know how to describe it. I am new in OpenGL world.

Just like you have a cube and you make a rotation on this cube… Then you want to generate a movie from this…

glReadPixels(…) at each frame and save the data in an appropriate format, i.e. bmp, tga or whatever. so you get frame01.bmp and so on. Use other software to create the movie. Or maybe look at something such as the quicktime libraries, which may do this sort of thing.
