Mixing OpenGL and normal SDL drawing functions

SDL Development
1

Hi,

i’d like to draw some 3D stuff using OpenGL and after that
add some things with SDL drawing functions.

Is this possible somehow? I already got the hint that i need
to draw in a texture and overlay that one.

Is this the only way?

Does it basically work like this:

  1. create an SDL_Surface with SDL_CreateRGBSurface()
  2. clear that Surface with SDL_FillRect()
  3. Draw into it
  4. glLoadIdentity(), glOrtho(0, w, 0, h, 0, 1)
  5. copy SDL_Surface with glDrawPixels() to screen

Can i save a screenshot of the result to a file?

Best regards,
Torsten.

we already discussed that last week (thread opengl+sdl);

here’s my suggestion:
draw 3d stuff as normal,
for 2d sprites: load the image as texture and draw it on a plain rectangle.

that’s it> Hi,
