Still digging into the source of the
outofmemoryerrors, but since I increased the heap to 128 it happens less
frequently. But what happens if you specify a 128MB heap size on a machine
with less than 128MB? (Realizing that's not neccessarily a question for this
group).

I just tried this on my Dell 8000 with a Geforce2Go 2, and it returned
a max degree of 2.0. So, maybe it is the driver you are using.

Hi Artur,
When you are *retrieving* the IndexedGeometryArray from the
GeometryInfo, are you specifying the flag "USE_COORD_INDEX_ONLY"
as a parameter to geomInfo.getIndexedGeometryArray( flag..) ?
IIRC, it also takes other flags such as NIO, ByRef, etc.
If you're already aware of it, then please
I believe it's due to the floating point precision, so 1.0 and 0.99 are
essentially the same thing. Because of the inherent inaccuracy in representing an
infinite number of real values in a 32-bit number, these type of round-off errors are
common.
For example, when doing an equals com
Is this possible to force GeometryInfo to output IndexedGeometryArray
with USE_COORDINATE_INDEX_ONLY set ? I can use it to give only single
array of indices to GeometryInfo, they are processed correctly, but on
creation of IndexedGeometryArray this state seems to be lost.
It seems that

It is being worked on within the JDK groups. I don't have a

this way.

In the meantime, as the bug seems to be in the auto computation

in vertexFormat = foo.getVertexFormat();
if( (vertexFormat & GeometryArray.BY_REFERENCE) ==

..query a GeometryArrayobject to find out if it is BY_REFERENCE or not?
I thought getVertexFormat() should work but the vertex format is input as a bitmask
i.e.
GeometryArray.COORDINATES | GeometryArray.NORMALS | GeometryArray.BY_REFERENCE
How can I get just the BY_REFERENCE bit?

There are different "1.0" versions. CVS does not have a concept of 1.0.
