texture projection vs a texture map

[thorsnuts]

Hello...

I was wondering what the difference between texture map and texture projection.

The reason I ask is I don't know when its appropriate to use either one for a specific reason. Usually I just apply a material and the use render tree to create the map automatically when I use a texture like fractal or whatever...

I just want to know what I doing when Im doing it. that's all...

thanks for the time

Had to look it up first...

A texture_projection is the UVs themselves, which often have an operator attached that generates them --- that operator in turn can have a texture_support object as an input that serves as a UI widget for controlling the operator (projection direction scale etc...).

A texture_map is a texture_projection plus an attached image that you can use to drive some parameters like push height in the push operator. Only parameters that are 'per point' can be driven by a texture_map. With local subdivsion+push operator you can create a displacement map preview like that.
