[JAVA3D] appearance problem

[Madeti, Henu S. (UMR-Student)]

 

        Hey all,

        I’m having a problem with the appearance of a shape3d. I created a shape3d 
from a triangular array, which I obtained from object file geometry info. Now when I 
set appearance for this shape3d they do not work. Please help me out. I guess it’s 
the lighting problem which I have it enabled. Textureattributes work fine but not the 
lighting effects.

        Here is the piece of code

         

        TriangleArray ta1 = new TriangleArray (

                     2709,

                     TriangleArray.COORDINATES

                 );

         

        ta1.setCoordinates(0, coo1);

         s = new Shape3D(ta1);

         

        Material m = new Material();

            Appearance a = new Appearance();

         

         //texturing takes place fine

        Texture tex = new TextureLoader(texImage, this).getTexture();

                    a.setTexture(tex);

                    TextureAttributes texAttr = new TextureAttributes();

                    texAttr.setTextureMode(TextureAttributes.MODULATE);

                    a.setTextureAttributes(texAttr);

                    a.setTexCoordGeneration( new 
TexCoordGeneration(TexCoordGeneration.OBJECT_LINEAR , 
TexCoordGeneration.TEXTURE_COORDINATE_3) );

         

         //culling takes effect too

        PolygonAttributes pa = new PolygonAttributes();

                    pa.setCullFace(PolygonAttributes.CULL_NONE);

                    a.setPolygonAttributes(pa);

         

        //appearance does not take effect

         m.setAmbientColor(1.0f, 1.0f, 1.0f);

        m.setDiffuseColor(1.0f, 1.0f, 1.0f);

         

                     m.setSpecularColor(0.3f, 0.3f, 0.3f);

         

                    m.setLightingEnable(true);

                    m.setShininess(100.0f);

            a.setMaterial(m);

        s.setAppearance(a);

         

        objTrans.addChild(s);

         

        thanks

        venu
