[SDL] Performance with 2D graphics and no OpenGL

[Edward Byard]

Hey Tom

No point using OpenGL for 2D applications, IMHO. SDL is more than capable, and also there is the SDL_gfx library which can rotate and scale (rotozoom) your surfaces.
Not great for real-time application but just cache the data.

Subject: [SDL] Performance with 2D graphics and no OpenGL

Hello,

 

I am writing a really simple little demo that is entirely 2D, but has a bunch of sprites that need to be scaled and rotated fairly often. I am writing it in vanilla SDL without any OpenGL, but now that I am about half way through I am beginning to worry whether this will affect the performance of my application too much. Would using OpenGL be a better option in this case? I am not really looking forward to learning how to figure out all this stuff in OpenGL and re-write a whole lot of code, so if it is the best option to use OpenGL if anyone could point me in the right direction to find some good resources that deal with OpenGL and SDL for 2D applications I apprecaite it. If, on the other hand, using regular SDL should be okay for this application, then please let me know. Thank you!
