I like to learn about BSP rendering

I like to understand the basics of BSP tree rendering. I am looking to the doom source code also to understand the simplest form from the beginning. Maybe i can write a win32 program with drawing pixels and lines to see how it works. I dont know how the doom code works just by looking at it, i cant even find the part where they draw a pixel. Also intrested in how to implement your own BSP tree in dirextX, how do i use the vertexbuffer for that ? Do you need to replace all vertices from the vertex buffer for every frame ?, aint that slow ? I need if for unlimited lights, in the fixed pipeline i have only 8 light sources available. I also dont understand how you make your own pipeline ?, how does it work in combination with a video card ?, i dont wanto code asm or shader language or something : C++ only, is it possible ? Anyone has undestandable info about the simplest BSP tree or non fixed pipeline ? thanks
