ahhhhh, i do believe that the bumpmapping and shadow mapping are 100% bug free, woooty

That's a pretty nifty approach, but have you worked out how to shade sprites to match the environment (with the shadows)?
Sorry to keep asking dumb questions, but you work fascinates me... I've always been a big fan of software rendering for some weird reason.

You can sample one point or a radius around the sprite's center position and use that to light the entire sprite... that's one of the most accurate ways to do it for sprites. Games like Chrono Cross did that (even though their environments were the reverse - models on 2D backdrops), and it works okay.
Anyway, good work so far. Looks pretty nice. It might be worthwhile to look into writing a custom app to do the shadow casting instead of integrating it into the editor; that way it can run in a seperate thread in the background while you do something else. That, and it will cut down on the editor's size and RAM usage, and you can enable extra processor optimization settings in your compiler. (Unless you're using QB for this, in which case, port the shadow casting to C++ :p)
Also, offhand, how much extra ram does the shadow map/shadow maps use up? And does it hurt performance too much, or is it composited onto the poly textures at load/process time?

that sounds like a good idea with the sprites. i need to try to find the processor thing in msvc, the map editor with 500 polies uses ~16meg ram, and all the lighting is written to the poly's texture to save space, and so the base engine drawing method did not need to be changed and ran at the same speed

By "processor thing", do you, by any chance, mean the optimizations? In both VS .NET and VS6 they're in Project Options, which you can access from the project menu (in VS6), or by right-clicking the project in the project browser and selecting "Project options" (in VS .NET).

You know CVS is more than just a way to release things to the rest of the team right? It would be nice to see intermediate updates and it makes you point out each change you made in the process. It also allows the rest a view on what is going on, and stay more involved.
Now that we've used CVS for BBRpg intensively, I'm using it for websites and school projects as well. I do this in a local CVS tree stored in /cvs/root, but that can be accessed from anywhere by anyone with SSH access to my laptop. It's just that much convenient for many reasons.

Not to mention the fact that it provides a nice mechanism for backing up data. You'd literally have to delete the whole $CVSROOT tree in order to loose anything.

For lighting the sprites you could check if the sprite is infront or behind the light source and lighten it or dim it depending on the normal of the plane to the light vector - err that would look kind of dumb, if the sprite was right next the light source sideways the sprite could be very dark.
How about just using the test; infront or back then lighten or darken with the intensity? Sorry if this was already mentioned, I didn't read all the posts....

Don't feel bad. I don't even know how to rotate a single point in 3-D space.

Heh... funny :)
That principle is the backbone behind ALL 3D animation, not just camera rotation.
