Triangle without color Information
Many Triangles in a “*.tri” file, Each triangle have a leading string “Triangle”.

Then followed 3 lines are 3 points(vertex) of the triangle.
Each point here have 6 float point values: x,y,z,nx,ny,nz.
x,y,z are (x,y,z) of a point, nx,ny,nz are Normal vector of a point.

Triangle with color Information

It is almost the same of the first format. But there is one more line of colors: fr,fg,fb, br,bg,bb.

(fr,fg,fb) are the front side color (Red,Green,Blue) of triangle. (br,bg,bb) are the back side color (Red,Green,Blue) of triangle.
