Hi, i wonder if there is something in this discussion
that might be related to the reason why when applying
a texture appearance to a sphere while running directx
install I am able to see lighting effects, however
with opengl I don't see the lights.
I saw that the discussion reffered to
new TexCoordGeneration ()
whereas my implementation, as follows maybe the newbie
approach, thoughts appreciated :)
Material material = new Material( white , white ,
white , white , shiny );
material.setLightingEnable( true );
Appearance app = new Appearance() ;
app.setMaterial( material ) ;
Texture2D tex = (Texture2D) new TextureLoader(
image_url, component ).getTexture();
tex.setMagFilter( Texture.FASTEST );
app.setTexture( tex );
TextureAttributes texAttr = new TextureAttributes();
texAttr.setTextureMode( TextureAttributes.MODULATE );
app.setTextureAttributes( texAttr );
int numSegments = 20;
Sphere sphere = new Sphere( radius,
Sphere.ENABLE_GEOMETRY_PICKING |
Sphere.GENERATE_NORMALS |
Sphere.GENERATE_TEXTURE_COORDS,
numSegments, app
);
