Modeling Colors: Emmisive, diffuse ... Created 16 years ago2008-11-21 16:20:54 UTC by Tetsu0

Hey guys. I got an application fo my iphone called iTracer.
It's a free 3-D modeling application, and i have a couple questions regarding render properties for an object.

In the Material options, there's different categories such as:
Colors:
-Emissive
-Diffuse
-Specular
-Specular power

Parameters:
-Reflectivity
-Opacity
-refraction index
-Fresnel reflectivity
-Fresnal power.

I was just wondering what those do.
As i've tried to mess around with different options but i can't see any noticeable difference what i render, and i don't know what causes what.

Those are only for in-program effects. Milkshape has those 4 too.

Emissive: The color and magnitude of which specified areas of the model are self-illuminated. If its cranked up all the way, the model won't have any shading.

Diffuse: In Milkshape, its the transparency level. But I think its different for a lot of modelling software. The "diffuse map" is the base texture without bump maps or specular maps applied, so I would guess it has something to do with textures. If you don't have any applied, you should apply a test texture to see.

Specular: How light is reflected and refracted when it hits the model. You can do a lot of things with specular, but usually its used for things like "phong gloss".

yeah. This isnt a texture based program, it's all color based.
so each of the 3 color controls has it's own palette to adjust
