Hi,
ok this is definitely strange. This is what my draw implementation looks like
now:
Code:
osg::State& state = *renderInfo.getState();
state.setVertexPointer( 3, GL_FLOAT ,0, &(*verts)[0] );
state.setColorPointer( 3 , GL_FLOAT ,0 , &(*colors)[0] );
for ( size_t i = 0; i < active->size(); ++i )
{
if ( (*active)[i] )
{
state.glDrawArraysInstanced( GL_LINE_STRIP, (*startIndexes)[i],
(*pointsPerLine)[i], 1);
}
}
state.disableVertexPointer();
state.disableColorPointer();
It works if I only render a few lines, like 2000 or sometimes even up to 35k.
More than that it always crashes in the glDrawArrays call, the point at which
the crash occurs is pretty random. Since i tripple checked all my arrays ten
times, the only thing i can think of now is that something changes the OpenGL
state, thus invalidating the vertex pointer. Now is there a way to check on
that guess and if it's the case to prevent it somehow?
Thank you!
Cheers,
Otto
