Mesh design

Hi all, i'm designing an api independent mesh and want to know what you think about it. a mesh has different primitivegroups. Each primitivegroup contains a bunch of primitives and a stateChange.A stateChange represent all the changes in the graphical pipeline according to a default set. A stateChange contains a material, renderstates, and textureStages. Each textureStage contains a texture,textureStates and samplerstates. All primitive groups are send to a renderQueu. The queu will sort the primitivegroups acoording to the same stateChange thx in advance [edited by - freaker13 on March 24, 2004 10:55:12 AM] [edited by - freaker13 on March 24, 2004 11:37:37 AM]
