However all that seems to happen is that the color I've specified for the Shape3D object is displayed purely i.e. no shading at all just 100% the same color all over the object. The only effect the light seems to be having is direction i.e. you can only see the shape at all when one surface is pointing down the way. I've tried both AmbientLight and DirectionalLight and they are both having no effect.

Any idea how I can realize it? I'm asking because the Base64-class I found on sourceforge needs a serializable-Object to encode it - or an array of byte. But Texture isn't serializable - BufferedImage neither. And how can I get an Array of byte of the image? I appreciate any answer. greets Gilberthttp://www.sagewire.org/3d-java/Encode-the-image-of-texture-with-Base64-53672.aspxrss@sagewire.orgMon, 20 Mar 2006 21:01:02 GMThttp://www.sagewire.org/3d-java/how-to-stop-interpolator-53669.aspxi created a Interpolator like this:PositionInterpolator moveDuck = new PositionInterpolator(duckAlpha,duckMovXfmGrp,axis,-30.0f,30.0f); it is a duck moving from -30.0f to 30.0f.

OpenGL via JAVA bindings, like Jogl, currently under development... 3.
