hi there,

i got access violation errors when rendering scenes requiring photon
mapping. i'm wondering if this is a known bug and if there is any
solution.
i tried the binary on the CD, it works fine. but the one i compiled
from the source code posted on the web page is always problematic.

i'm using visual studio 2005 under windows xp.

thank you.

Hey,

The problem is actually in core/kdtree.h. Change line 96 from
	std::nth_element(&buildNodes[start], &buildNodes[splitPos],
		&buildNodes[end], CompareNode<NodeData>(splitAxis));
to
	std::nth_element(buildNodes.begin() + start, buildNodes.begin() + splitPos,
		buildNodes.begin() + end, CompareNode<NodeData>(splitAxis));

Cheers!
