read textures


Anybody knows how can I read pixels from a texture that is on a texture name array?

Now, I read directly from the frame buffer to update the texture when I render it, but I don´t want to do this because I want to read a texture that is already in my textures array. The image that I read from the frame buffer is modified and I don´t want that image.

Please help meeee


If I do glGetTexImage, my aplication stops

Then start your debugger and look why.
If you’re sure it’s not your fault, try a new graphics driver from your graphics card vendor.
If it still doesn’t, work file a bug to the developer relation department of that vendor.
