Rendering a scene
Author
Hey guys, I'm having problems rendering a supposedly simple scene. I just want to draw three quads to the screen using DirectX9 in C++ and all I'm seeing is a black screen (which means that the Clear call is working). Can someone take a look at the code and tell me why I'm not seeing anything (maybe the vertices are being drawn or transformed off the screen, maybe I'm not drawing the vertex streams right, who knows).
I don't see a view matrix created anywhere. You need to make one using D3DXMatrixLookAtLH(&view,&eye,&at,&up); Then once you've done that, you need to make your viewProj matrix using D3DXMatrixMultiply(&viewProj,&view,&proj); Then set the correct matrices (I know you need to set D3DTS_WORLD like you do, but I don't remember about view and projection matrices. I usually use shaders so I'm not used to this). See if that helps.
