Oh dear... did I really jimp you? Well, jimb you instead!
Here's a version that has a save and load function for the settings and it's all on buttons... thinking of which...hmmm, I should probably make a button for turning on/off background as well. ...couldn't I have thought of that earlier.
Anyway, trackballs and spanish keyboards are currently waiting for a "donation" button on my website, but are eagerly bouncing up and down to come out! ;D ...nah, I'm kidding. I'll see that I make some nicer handling for everyone.
Kidding, again! ;D
Alright, I'll add that background toggle and look for some way to customize a few of the keyboard shortcuts.
i wonder if Dr Petter could add textures or picture projection into this. lt me see if i can clarify tis a little right now you have just lights with specular and subsurface scattering kind of. so the most you can do is some swet but simple light effects around a sphere what if you could load up either (or both) a 2d bitmap projection image that can be moved around the sphere but ALSO be affected by any lights in the scene, and on top of that load up a bumpmap image for giving the surface some texture as well a bit like painting a bump in paint mode (which never works right for me) but this bump is inherrent in the texture file. having the ability to mess around with several picture and bump images i think could make for some truly stunning texture files for sculptris.
It's a simple, but neat trick... A 3d geometry provides a 3d program with very simple surface information. One of such are so called "normals". They describe a vector in which a polygon is facing. To cover all directions in one single form you generate a sphere. It's surface shows into all directions over its body. You will find most of those directions in every complex shape, actually.
Now, instead of using those normals to calculate proper lighting, simply assign a color to each direction. In this case, it maps the image of a sphere instead of onto the screen onto normal directions. That's how that works. But I might be not too good in describing that.
