Losing my mind...


« Posted 2004-07-22 15:46:49 »

Hi,

I'm having problems with applying a transparent texture over  the top of another, the effect I want is as follows:

Base Texture  +   Texture Overlay (with alpha)  =   Desired result

I've tried what seems like every combination of TextureAttributes and various modes but no luck, surely this can be done? Here's the code I'm using

TextureUnitState tu0 = new TextureUnitState((Texture2D) TextureLoader.tf.getMinMapTexture("floor.jpg"), null, null);
TextureUnitState tu1 = new TextureUnitState((Texture2D) TextureLoader.tf.getMinMapTexture("test.png"), null, null);
TextureAttributes ta0 = new TextureAttributes();
ta0.setTextureMode(TextureAttributes.MODULATE);            // Mode needs changing???
tu0.setTextureAttributes(ta0);
TextureAttributes ta1 = new TextureAttributes();      // Mode needs changing???
ta1.setTextureMode(TextureAttributes.BLEND);
tu1.setTextureAttributes(ta1);

// ????
// Some combination of setCombineAlphaMode and setCombineRgbMode here ????
// The modes are not clearly documented which const values of TextureAttributes apply to each method?
// ????
 
// is order in the array important?
appearance.setTextureUnitState(new TextureUnitState [] {tu0, tu1});


Can anybody help? or at least explain the setCombineAlphaMode and setCombineRgbMode methods

Thanks....

Ben

Hi,

I suggest to check

http://oss.sgi.com/projects/ogl-sample/registry/EXT/texture_env_combine.txt

as starting point.

OK, this one is too low level maybe... but this is original source - the rest is just interpretations of this one.
