Maratis Tiny C library

======================



is a collection of small and efficient math and image processing routines written in ANSI C with no dependencies.



The library is divided in independent single files (stb style):

- [m_math.h](https://github.com/anael-seghezzi/Maratis-Tiny-C-library/blob/master/include/m_math.h)

- [m_image.h](https://github.com/anael-seghezzi/Maratis-Tiny-C-library/blob/master/include/m_image.h)

- [m_raster.h](https://github.com/anael-seghezzi/Maratis-Tiny-C-library/blob/master/include/m_raster.h)

- [m_dist.h](https://github.com/anael-seghezzi/Maratis-Tiny-C-library/blob/master/include/m_dist.h)

- [m_path_finding.h](https://github.com/anael-seghezzi/Maratis-Tiny-C-library/blob/master/include/m_path_finding.h)



Math

----



* vector manipulation

* interpolation (cubic, catmullrom)

* quaternion (basics, slerp...)

* matrix (projection, transformation...)

* random number generator

* 2d routines

* 3d routines

  * voxeliser (tri-box overlap)

  * raytracing (sphere, plane, box, triangle)



Image manipulation

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



* ubyte, ushort, int, half, float...

* copy, conversions, mirror, reframe, rotate...

* filters (convolution, gaussian blur, sobel, harris)

* resizing, pyrdown

* morphology (floodfill, dilate, erode, thinning...)

* corner detection (harris, non-maxima suppression)



Rasterization

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



* triangle with interpolation (perspective correct)

* basic line, circle and polygon



Distance map

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



* distance transform and voronoi



Path finding

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



* path finding on regular grid (floodfill-based)
