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.
