It would be amazing if you used multi-pass lighting and etc. techniques I know very little about to allow more than 8 lights at one time.
The rough idea, as I've read it, is that you render the scene with the first 8 GL lights, then with the next set, then the next, and keep going until all lights are rendered.
... There's probably a better way to render large numbers of lights. Thus why I'm asking you, the much more skilled-with-OpenGL developer, to look into the possibilities.

Adding pan movement to the orbit camera would be nice addition. Panning would move the "look at" target and therefore rotations would still orbit around the new location. Smooth in and out movement using mouse click+drag in addition to wheel wheel steps would also be a nice addition. Perhaps right mouse which really isn't used for anything new here could be used to smoothly move in and out. Hold RMB+move mouse up moves in and down zooms out or something like that. You could also use the middle mouse button instead of the right mouse button for movement.

The in/out movement is separate from zooming which affects the FOV. I am not suggesting a zoom feature here.

Hi. I quite like this, having removed the ppsm shader call to get it to work on my laptop - would be nice if it dealt with this more gracefully..

Anyway, I noticed the camera mouse delta update code suffers from gimball lock (though it's all quaternion based.. I thought it would be ok).. so I've implemented an arcball-like solution on top of what's there. It's only a couple of methods on the camera class.. seems to work ok.. would you like it?

I've got it running inside a opentk GLControl, which was also a little fiddly. Might be nice to sort out that and include a demo..

Hello,

How change texture on OBJ or md5 meshs?
Changing Mesh.textureMaterial or Object.textureMaterial does not work.
After loading and instancing mesh on scene *_.texture Material *_always NULL.

Hello
Instead of use of the static OBJ, is support of the Autodesk FBX format planned?

I was looking for a way to change an SSObjectMesh's texture while the program is running. My attempt at it was:

myObjectMesh.textureMaterial = new SSTextureMaterial (myNewTexture);

However, this doesn't seem to do anything -- I'm guessing I'm misunderstanding how SimpleScene handles this, looking for any suggestions! Thanks.

        SSAssetManager.AddAssetArchive(new SSAssetArchiveHandler_FileSystem("./Assets"));
            SSAssetManager.AddAssetArchive(new SSAssetArchiveHandler_FileSystem("../../Assets"));

            }

open in visual studio. Compile all. Fine.
GDiviaAGGTest works fine
But all TestBench fails at this stage
=> throw new Exception

I do like the shadowmaps, models are bright on the lighted side, however the darker sides are pitch-black. Even if I set lighted to true on the object I don't see a difference. In older versions the shadowmap wasn't as advanced but models could be rendered with flat lighting and no shadows. I looked around the entire project but could not find a way to recreate this, disabling the shadow map simply renders the object black.

Thanks for your excellent IcoSphereCreator. After generate this MeshGeometry3D object

1. Is there any to find out which triangle a vector is inside?
2. Is there anyway to generate a MeshGeometry3D object where the elevation angle must be larger than a certain angle?

The first if statement in the following code snippet (in file ssBVH_Node.cs)

           // perform the best rotation...            
            if (bestRot.rot != Rot.NONE) {
                // if the best rotation is no-rotation... we check our parents anyhow..                
                if (parent != null) { 
                    // but only do it some random percentage of the time.
                    if ((DateTime.Now.Ticks % 100) < 2) {
                        bvh.refitNodes.Add(parent); 
                    }
                }                
            } else {
                // ...
            } 

should be replace by the following line of code???

if (bestRot.rot == Rot.NONE) {
