KD-Tree...[5804:100000]
KD-Tree Build Time = 0.078817s
+ Nodes = 3437
+ Leafs = 1719
Intersection Time = 2.00325s
Triangles Checks = 186
Intersection Time <osg> = 27.5296s
Total Bench Time: 29.6118s
How and where should i implement this feature to test with normal OSG
rendering. Vertex Array change to complex objects ?
