how can you create a CompressedGeometry from a Primitive? my problem is that i wanted to save a shape created by the user from primitives to a file. i found that CompressionStream can accept Shape3D and output a CompressedGeometry but as i understand, only the material diffuse colors are kept (if

Hello, I would like to use the CompressedGeometry class and utilities, but I am a bit concerned about the following statement taken from The Java 3D API Specification's Appendix B "Java 3D uses a compressed geometry format that allows 3D geometry to be represented in an order of magnitude le

hi,   CompressedGeometry in the API doc talks much about improving download speed across networks but when i try to use CompressGeometry in an Applet, a Security Violation occurs.  Is the CompressedGeometryFile using a similar object to the File object (which i know causes all kinds of secur

Dear Jack, you are right, Java 3D doesn't rescale the coordinates of the compressed geometry. You have to do this by hand. Notice, that since Java 3D 1.2 there are two Point3Ds called upperBound and lowerBound in the CompressedGeometryHeader, which you can use to store the original scale of your

2000-09-25 Thread Jack Pien
hi,   i'm trying to save a J3D scene graph into a number of CompressedGeometryFile's.  i noticed that the CompressedGeometry clamps coordinates between (-1,1) probably as part of the compression algorithm.  but when i try to reconstruct my new scene graph using CompressGeometryFile object, J
