Mikkelsen + * Version: 1.0 + * + * The files mikktspace.h and mikktspace.c are designed to be + * stand-alone files and it is important that they are kept this way. + * Not having dependencies on structures/classes/libraries specific + * to the program, in which they are used, allows them to be copied + * and used as is into any tool, program or plugin. + * The code is designed to consistently generate the same + * tangent spaces, for a given mesh, in any tool in which it is used. + * This is done by performing an internal welding step and subsequently an order-independent evaluation + * of tangent space for meshes consisting of triangles and quads. + * This means faces can be received in any order and the same is true for + * the order of vertices of each face. The generated result will not be affected + * by such reordering. Additionally, whether degenerate (vertices or texture coordinates) + * primitives are present or not will not affect the generated results either. + * Once tangent space calculation is done the vertices of degenerate primitives will simply + * inherit tangent space from neighboring non degenerate primitives. + * The analysis behind this implementation can be found in my master's thesis + * which is available for download --> http://image.diku.dk/projects/media/morten.mikkelsen.08.pdf + * Note that though the tangent spaces at the vertices are generated in an order-independent way, + * by this implementation, the interpolated tangent space is still affected by which diagonal is + * chosen to split each quad.

The normal map sampler must likewise use the +// interpolated and "unnormalized" tangent, bitangent and vertex normal to be compliant with the pixel shader. +// sampler does (exact inverse of pixel shader): +// float3 row0 = cross(vB, vN); +// float3 row1 = cross(vN, vT); +// float3 row2 = cross(vT, vB); +// float fSign = dot(vT, row0)<0 ? -1 : 1; +// vNt = normalize( fSign * float3(dot(vNout,row0), dot(vNout,row1), dot(vNout,row2)) ); +// where vNout is the sampled normal in some chosen 3D space. +// +// Should you choose to reconstruct the bitangent in the pixel shader instead +// of the vertex shader, as explained earlier, then be sure to do this in the normal map sampler also. +// Finally, beware of quad triangulations. If the normal map sampler doesn't use the same triangulation of +// quads as your renderer then problems will occur since the interpolated tangent spaces will differ +// eventhough the vertex level tangent spaces match. This can be solved either by triangulating before +// sampling/exporting or by using the order-independent choice of diagonal for splitting quads suggested earlier. +// However, this must be used both by the sampler and your tools/rendering pipeline. + +#ifdef __cplusplus +} +#endif + +#endif diff --git a/mons_3d/external/mikktspace/src/mikktspace.c b/mons_3d/external/mikktspace/src/mikktspace.c new file mode 100644 index 0000000..0342ae0 --- /dev/null +++ b/mons_3d/external/mikktspace/src/mikktspace.c @@ -0,0 +1,1899 @@ +/** \file mikktspace/mikktspace.c + * \ingroup mikktspace + */ +/** + * Copyright (C) 2011 by Morten S.
