Compressed geometry has no user defined texture coordinates associated
with it. The only way to do texture mapping with compressed geometry
is to use texture coordinate generation.

Hi,
Can anyone tell me how to add texture data in the while using the
CompressedGeometry.
It's very easy to add texture data in the TriangleArray class.
But when i use texture coordintate loaded GeometryInfo to make
CompressedGeometry,
java3d fails to apply textures.
Can you tell me where am
I am also thinking of putting a CompressedGeometry into a JavaSpace. But for
an Entry's data to be stored, its data members must be declared public. I am
wondering how to get around this issue.
Could a CompressedGeometryFile be written onto a StringBuffer, or some
similar idea?

Hi All,
I am wondering how can I send a CompressedGeometry
object across the network. The CompressedGeometry
class does not support Serializable interface.
Thanks.

Wouldn't it be simpler to explain it as something like "round off
error"? (perhaps not technically accurate but it should be easy for most
people to understand).
Imagine "compressing" doubles to floats, the fine precision is lost but
the rough number is the same (and uses half the storage).

Hello again-
I'm trying to get CompressedGeometry to work. I can save a single piece of
geometry to a file, and then load it back in. Everything is great except
the coordinates have been scaled and translated into [-1,-1,-1] to [1,1,1].
I am assuming that I'm doing something wrong. Any ideas o

Hi folks,
I want to build a server application, that sends a set of
IndexedTriangleArrays to an applet. To minimize the amount of data, I
tried to use a compressed geometry build by the
com.sun.j3d.utils.compression classes. But I faced a lot of problems.
First, it seems, that the normals or nor
