add MSVC compiler support, make it default for Windows new header file simd.h for SSE abstraction and helpers add mselect pseudo instruction for common or(and(...), andnot(...)) replace many SSE intrinsics with new names new MemoryPool class (mempool.h) for faster KdNode allocation remove setMaxDepth() from Octree and KdTree, make max_depth const, it should be defined in constructor and never changed, change after building tree would cause error in traversal modify DefaultSampler to generate nice 2x2 packets of samples for packet tracing optimize Box and BBox::intersect_packet add precomputed invdir attribute to RayPacket scons build system: check for pthread library on Windows check for SDL generate include/config.h with variables detected by scons configuration move auxiliary files to build/ add sanity checks add writable operator[] to Vector

Container Usage

    18

---------------

    19

(Container|Octree|KdTree) top;

    20

scene.setTop(top)  // top object in hierarchy

    21

top.optimize()     // build optimization structure

    22

    23

Rework camera

    24

-------------

    25

Sampler - generate points in screen plane

    26

Camera - transform point from sampler to a ray
