No it doesn't do anything to work with retina displays right now. It's on my todo list but not too close to the top at the moment.
Hi,
If you are using a custom NSView and NSOpenGLContext, it shouldn't be too hard to make it work for retina, you would want to set :
Then you want to save your backing store scaling :
Then you can use it to adapt your opengl viewport accordingly :
That should be sufficient to benefit for the high res on retina displays (ie there should be no need to modify your rendering code)
Hope that helps !
If you are using a custom NSView and NSOpenGLContext, it shouldn't be too hard to make it work for retina, you would want to set :
1 | [view setWantsBestResolutionOpenGLSurface:YES]; |
Then you want to save your backing store scaling :
1 2 3 4 5 | NSRect bounds = [view bounds]; NSRect backingBounds = [view convertRectToBacking:bounds]; float scaleX = backingBounds.size.width/bounds.size.width; float scaleY = backingBounds.size.height/bounds.size.height; |
Then you can use it to adapt your opengl viewport accordingly :
1 | glViewport(0, 0, width*scaleX, height*scaleY); |
That should be sufficient to benefit for the high res on retina displays (ie there should be no need to modify your rendering code)
Hope that helps !
That does help a lot! I'll bump it to the top of the list.
