OpenGL and 2d

SDL Development
#1

With any 3d game it is very common for there to be 2d information boxes
splatted on top. Is it better to use OpenGL or SDL for these?

Using OpenGL seems limited in terms of the size of the box and the
number. How many textures can OpenGL support?

By using SDL I mean using SDL surfaces and blitting them on top. Does
this method have any problems? Any problems with speed?

Thanks,
Adam.

hrm, just over 4 billion, but I think your memory will be all gone
long before :slight_smile:

most games just use a texture as a ‘billboard’, some hw won’t let you
do a 2d blit over a 3d context…
