Rendering directly on texture

SDL Development
1

Hi,
I was wondering what were the different SDL or GL functions I should
read about in the manuals in order to make a direct render into a texture.

I mean, I would like to draw an OpenGL scene in a texture instead of
the frame buffer. In a 256x256 texture for example…

Thanks in advance!

I think this tutorial shows how to render to the framebuffer and then
copy the pixels to a texture, which is slow… I’d need to take a
texture as a framebuffer.
