How to Draw polygon index in Direct3D
Author
Hi guys !!
I have a problem in D3D.
because my BSP engine is use this two function to draw polygon :
////////////////////////////////////////////////////////////
glBindTexture(GL_TEXTURE_2D, m_textures[pFace->textureID]);
glDrawArrays(GL_TRIANGLE_FAN, pFace->startVertIndex, pFace->numOfVerts);
////////////////////////////////////////////////////////////
But I want to how what function in Direct3D is same to this
thanks
DrawIndexedPrimitive(), except that you will need a vertex buffer and index buffer. Drawing faces one at a time is absolutely horrible for performance so you should group sets of faces into vertex/index buffers and make a single call per set. A given call should render atleast 200 triangles, optimally thousands on the latest hardware. Also lookup CreateVertexBuffer() and CreateIndexBuffer(). The docs explain this stuff pretty clearly.

Thanks ,How about DrawPrimitive,
because I need to render a BSP map in direct3D
the face is different in every frame.
