   Rendering sprites without sorting?
  Hello,From my understanding, I''ve to disable depth test and sort the sprites based on the z distance before rendering them. Is it possible to render them correctly without sorting? Because my model contains sprites and I don''t want to sort all polygons... Thanks. 
  You only have to sort the polygons that are in the view frustum, which should not be a huge number.  Otherwise you will be spending more time drawing than sorting anyway. ;  Thanks. Hopes the frame rate won't drop much  [edited by - mannam on August 6, 2003 1:28:14 AM];  You also don''t need to do sorting if you do only additive blending or only subtractive blending or only multiplicative blending.   ;  And you don''t need to disable depth testing and sort the polygons if you use alpha testing instead of alpha blending for your sprites.Geezzz. I really hope that NeHe changes his masking tutorial to include aplha testing as another option. I can''t remember the amount of times i''ve written a similar reply to this one.

GL. ;  I can render my model corretly now. Thanks all!
