xNormal

xNormal from Santiago Orgaz is a free application to generate normal / ambient occlusion / displacement maps. It can also project the texture of the highpoly model into the lowpoly mesh ( complete texture transfer, even with different topologies ).
It includes an interactive 3D viewer with multiple mesh and textures format support, shaders and realtime soft shadows / glow effect.
xNormal comes with some useful tools like height map - normal map - cavity map - occlusion - tangent/object space and spherical harmonics tools. All these computations are done using multicore/multithreading, distributed/parallel rendering, ray tracing and advanced GPGPU techniques.

xNormal is available for Windows.
