Title: D3D equivalents for OpenGL
Post by: taj on February 10, 2008

Does anyone know what the equivalent D3D command of

glRecti(-1,-1,1,1);

would be? I'm hoping I dont have to use vertices but call some primitive instead...

Good question, taj.

I really do not know - had a search on the net. All I
found was the following thread saying what you do
not want to hear (using vertices) ...

Sorry. Didnt find anything else...

Thats interesting, I'll try it and see if it triggers the shaders to run.

I doubt it, but worth a try.  Otherwise it's probably necessary to draw an indexed primitive.  Look up DrawPrimitiveUP() which takes vertices as a parameter and doesn't need a vertex buffer.
