you dont do glFlush in the SDL example,
that could be the problem.

gotten stuck in your mailfilter, if so please just ignore them

Subject: [SDL] GLUT works while SDL does not

I’ve ran into some problems using SDL 1.1.7+OpenGL under Windows… I got
this snippet of code that works when I’m using GLUT, but which only
displays
a blank screen when I replace GLUT with SDL. If anyone is interested in
looking at the minimal error-inducing program (actually an example from
the
red book), here are the two URLs:

http://www.iki.fi/~troezen/misc/drawf_sdl.cpp
http://www.iki.fi/~troezen/misc/drawf_glut.cpp

Something obvious might have slipped my mind… Anyway thanks.

Yep. Add a call to InitGL(100, 100); after SDL_SetVideoMode();

Obvious enough :slight_smile:

Thanks
