finish sample Primitives

description

Currently the primitives sample is:
 
  • unfinished (the different tests needs to be implemented)
  • using the XNA framework (to ensure that it is working as expected first)

fixed in revision #18365.Problem with instanced primitives was in the shader: Starting with DX10 POSITION0 must be changed to SV_POSITION.

The sample is finished but there's still a rendering error in the instanced primitives part (even in XNA version).

The XNA version of the sample is finished now. I'll start to move to ANX now and implement the missing features.

DrawUserPrimitives is implemented

DrawUserIndexedPrimitives is implemented

DrawInstancedPrimitives is implemented.

The current version of BasicEffect is not complete. It does not render like it should and needs some work to complete this sample.

Viewport problem is fixed... Four of the five viewports are rendered now. The instanced one is still missing.

There are different problems with the Draw*Primitive methods. They should be analyzed seperately because there are paging effects.

I added some options to deactivate the different test cases by key press.

DrawPrimitives and DrawUserPrimitives looks like the culling is broken.
DrawIndexedPrimitives and DrawUserIndexedPrimitives have some issues: If one is deactivated, the other one is affected.
DeawInstancedPrimitives is currently not working.

DrawIndexedPrimitives and DrawUserIndexedPrimitives are fixed now (source revision #18149).

DrawPrimitives and DrawUserPrimitives are fixed now (source revision #18152).

Glatzemann wrote Sep 21, 2012 at 12:08 PM

fixed another issue with DrawIndexedPrimitives in source revision #18165.

Remaining issue: DrawInstancedPrimitives is not working...

I've analyzed the draw instanced primitives issue. There are several problems:
  • Multiple vertex buffer instances are not working
  • Merging of Vertex declaration when using multiple vertex buffers are not working
  • Mapping of Vertex declaration to input layout not working when using multiple vertex buffers
I'm currently debugging this issues...
