Why shouldn't it be legal ? Geometry, Appearance, .. are NodeComponents, therefore the scenegraph only has references to them. there should be no problem to use two or more Shape3D's with one Geometry, Appearance, .. > Even with by-ref geometry my fear would be that Java3d > would have seperate display lists for each geometry array, even though it > is identical. First, I thought OpenGL implemetation is using VertexArrays when BY_REFERNCE is set ? Therefore the vertexData (not the vetexIndices) should be shared, if all vertex-arrays are set with the same data. Asuming that BY_COPYING indicates to use DisplayLists, I believe that each GeometryArray has a seperate DisplayList, but using the same Geometry in different Shape3Ds should be the same as drawing the same DisplayList more than one times.. regards -Michael Nischt ==========================================================================To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
