Hi!
I would:
1 Read your data into a Vec3Darray - as doubles
2 Decide upon a local origin - "best" may be the centroid of your data, but
the first point is somewhat quicker to find.
3 Subtract the local origin from all the points in your array - they are
now still doubles, but each is a much smal
Hello, Chris
Thanks a lot for your help and correction of my English. Once you
build these libraries, please send them to me via first_...@21cn.com

As Robert says, this isn't the osgEarth forum, and "demand" is a poor
translation into English. I think "request" is the word you should be using.
I might be able to help you obtain the GDAL+GEOS libraries, but I haven't
successfully made a 64-bit build of them yet, so you may have to wait a bit.
Sorry Robert,
I demand GEOS libraries here because they are dependency libraries
for OSGEarth.

Hi Glen,
Please use an appropriate forum for GEOS support. The OSG doesn't have
anything to do with GEOS so it's not an appropriate plase to go demanding
libs for.
Robert.
This might be related to an issue that I'm currently having. It seems that
during the transition from 3.0 to 3.2, binding per primitive was deprecated,
but the STL format binds its normal vectors per primitive. To deal with this,
there was an ad hoc addition to the STL plugin where the normals o
Hi, Robert
Thanks for your advice! I finally got back to this issue, and did as you
recommended. I loaded a few of the STL files in the osgviewer application, and
it had similar strange coloring problems (as seen in the attachment).
As you recommended, I looked at the change in the source code

Hi Peter,
thank you for the fast reply.
I need some clarifications about question 1.
In my application I will use the "picked" point to calculate, and then show,
the arclength of a path, i.e. the length of the path from start to the picked
point. So I would not need to show coordinates to the us

Hello Gianni,
2) line geometry is infinitely thin. To create an exact intersection with
another line in floating point precision is like winning the lottery. You
will want to use PolytopeIntersector to intersect with non-polygonal
geometry instead.

Hi All,
I'm trying to handle mouse movements to show some informations to the user.
I have basically two questions.
1) Lookig at "osgkeyboardmouse.cpp" example found the following code:
Code:
if (_useWindowCoordinates)
{
// use window coordinates

Hello All,
I met a problem in building GEOS project based on 64-bit Windows. If
anyone has GEOS static and dynamic libraries, please send them via Email.
Thanks a lot
