The sample uses the vertex format D3DFVF_LVERTEX, which indicates the vertices are pre-lit (they do not have DX apply lighting to them), but are untransformed. In otherwords the vertices use a set color and the vertices are in model coordinates. The 3 vertices for the triangle have diffuse colors of red, green, and blue.
So I have 2 questions:
1) Why is the triangle black? Shouldn't the format of the vertex just make the color of these vertices red, green, and blue. I expected a blended triangle.
2) Do the World, View, and Projection matrices have default values? SetTransform is NEVER called in this example.
Can someone please tell me what I am missing here? I am a newbie to D3D, and this one has me stumped.
