Image Description, by
I am currently working on my own 3D Engine that runs under Direct3D. At the
moment I am working on my Lighting Engine. The screenshots shows one of my nice
effects I have built into it. If a face is set to no shadow casting and a ray runs
through during processing the lightmaps, my routine gets the pixel of the texture at
that intersection point and the light ray then get's the color of that texel. That
works very fine as you can see in the image above. I am just modeling a Scene with
a lot of these windows (a church or something like that). In order to get the
lightmaps impressive with these FX, they have to be quite big. The ground lightmap
is 128x128 pixels and the lightmap is blurred after it is created.
