Algorithm to fill triangle
if it helps a bit here is my ancient C++ source for triangle in VCL/GDI: //————————————————————————— class gfx_main { public: Graphics::TBitmap *bmp; int **pyx,xs,ys; gfx_main(); ~gfx_main(); void resize(int _xs=-1,int _ys=-1); void troj(int x0,int y0,int x1,int y1,int x2,int y2,int col); // this is filled triangle void _troj_line(int *pl,int *pr,int x0,int y0,int x1,int y1); // this is … Read more
