No, it isn't impossible. I didn't work on that topic anymore. I will try to get my handy on it during the christmas days. I will convert the bumpmapping code to use vertex-attributes instead of the second texture unit's texture coordinates. Then the geometry isn't forced to have 3-dim-texture-coords anymore.

The current code would require you to replace the existing 2-dim-texture-coordinates by 3-dim ones (where the third coord is 0). But I guess, you can wait until I converted the code .

That's fine.  Thanks  .

It is possible now. Though I haven't managed to get the GLSL bumpmapping to work, the old Assembly shaders do work. And since we now have support for different texture-coodinates sizes on the same geometry, we can use the current bump-mapping factory.

You just have to call the shape.setBumpMappingEnabled( true, bumpMapTex ) method, and everything should be done automatically.

Thank you!

I just have tested your new changes on the BumpMappingTest: that's great !

But i have two remarks :

- The test BumpMappingTest2 is broken because some ressources missing:

Code:

java.io.FileNotFoundException: \space\workspace\xith-tk\test-resources\shader\shader.bump.vertex.glsl (Le chemin d'accès spécifié est introuvable)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:106)

at org.xith3d.effects.GLSLBumpMappingFactory.getVertexProgram(GLSLBumpMappingFactory.java:75)

- When i add an HUD, and if bumpmapping is enabled there's some strange HUD rendering results.
For example i have just added an HUD with one button, and one image on the test "BumpMappingTest" with this :

Code:

    private HUD createHUD(Canvas3D canvas, OperationScheduler opSched){
HUD hud = new HUD(canvas, opSched);

hud.addWidget(new Button(100f, 25f, "test"),10f,10f );
hud.addWidgetCentered(new Image(100f, 100f, "lena.dds"));
return hud;
    }

and this

Code:

        env.addHUD(createHUD(canvas, this.getOperationScheduler()), this.getInputManager());

And, depending on the light position, the HUD widgets are lighted or not.
But if the bumpmapping is disabled like this

Code:

torus.setBumpMappingEnabled( false, "normalmap.bmp" );

the widgets are OK

Sorry to be so annoying with all my bugs, i'm just learning how Xith works

Well, the BumpMappingTest2 is my personal testcase to work on GLSL bump mapping. So I didn't link to the jared shader files, but absolutely on my filesystem. When the test is working I will put the shader files back into the jar and this problem will be gone.

Good to know. I will check that.

You're not annoying. Actually I love good feedback.

I have finished the GLSLBumpMappingFactory, which is now used by default. It works and looks just great. Check it out...

Very nice rendering and job.
Moreover you resolved the HUD problem in the same time..

You're the bumpmaps's king, Marvin

No, that bug wasn't solved. It just didn't appear, since the AssemblyShaders weren't used. Now it is fixed .
