Re: [pygame] Dirty Rect Animation

Hello Yes I do dirty rect animation. If you read the code of the RenderUpdate (in pygame.sprite.Sprite.RenderUpdates) then you will see that this group does something like this: dirty = [ ] if old rect and new rect overlap: dirty_rect = old_rect.union(new_rect) dirty.append(dirty_rec

Re: [pygame] Dirty Rect Animation

I'm fairly certain that update does NOT merge incoming rects or do any other optomization on input. It iterates through all of the rects in the list and updates that portion of the screen. So you can optimize it considerably by merging rects where it makes sense, rather than sending a rect for

Re: [pygame] 3D sample code

You're right that you cant use any of the regular SDL drawing functions with OpenGL - or any other accelarated 3D API. You can work with 2D graphics in OpenGL though, by drawing texture quads. If you wrap that in a simplified interface, then the code doesn't look much different from what you are u
