[Papervision3D] Smart Textures

[Arne Strout]

I have been fiddling around with the best way to implement textures which have a bit more brain to them.Currently Face3D supports bitmap and color textures, but supports no callback based texture method.What I'm proposing is this:Modify Face3D to add a line in which there is a flag based callback to the Material object passing the Face3D object before any rendition of the texture / color for the face is done.This allows, for example, the texture to change it's color based on the location of the Face, or perhaps to create a gradient fill (Garoud / Z lighting? anyone?)This would also allow for distance fog, but I'm not going to get into the logic for that just yet.Any thoughts?Would the extra IF statement be too much weight?I'm thinking something along the lines of:if(material.smart){material.prepare(this)} // Where smart is a boolean property of MaterialObject3Dbefore the line (line 269):         if( texture )        {If this modification could be added I could start building some fun material choices without having to modify the current engine.-Arne G Strout
