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
• m_image.h
• m_raster.h
• m_dist.h
• 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)

Asm.js demos

• m_raster
• m_voronoi
• m_raytracing
