FortGL

3D software rendering in pure Fortran.

Features so far...

• Reads .obj and simple .ply file formats
• Bresenham's line algorithm
• Rasterisation of triangles
• User defined shaders
• Movable camera and perspective view
• Wireframe render of triangles
• Texture mapping
• Native output in ppm (with any format available through imagemagick)

Requirements

• Only tested on:
• gfortran 5.4.1+
• ifort 17.04+
• pgi 17.4-0 (requires changing all error stops to stops and remove call execute_command_lines)
• ImageMagick v 6.8.9-9
• Ubuntu 16.04 LTS

ToDo

• Fix wireframe render to use Nivida's solid wireframe render method
• Normal mapping
• Fix .obj for more than order 3 (i.e. more than just triangles)
• More file formats (.stl for model input, and image output formats)
