Hi,
I have a similar problem when i create an OSGTerrain node in a multithread
configuration. The crash occur in the init function of the GeometryTechnique
class. Note i use OSG 3.2.
To solve this problem, i made a small modification to OSG itself.
I replace the line
if (!_currentBufferData || !assumeMultiThreaded)
by
if (!_currentBufferData && !assumeMultiThreaded)
in the GeometryTechnique::init function.
I also replace the line
init(getDirtyMask(), false);
by
init(getDirtyMask(), true);
in the TerrainTile::traverse function.
With this modification, the currentBuffer is create in the Update traversal
(one thread) instead of the cull/draw traversal (multi-thread).
Maybe it's better to wait for OSG team approval before you made this
modification.
Cheers,
Sylvain
