Read surface mesh in STL binary format.

The STL format is a mesh format that is often used for 3D printing, it stores geometry information. It is known as stereolithography format. A binary and an ASCII version exist. This function reads the binary version.

Usage

read.fs.surface.stl.bin(filepath, digits = 6L)

Arguments

filepath

full path to surface mesh file in STL format.

digits

the precision (number of digits after decimal separator) to use when determining whether two x,y,z coords define the same vertex. This is used when the polygon soup is turned into an indexed mesh.

Value

an fs.surface instance.

Note

The STL format does not use indices into a vertex list to define faces, instead it repeats vertex coords in each face ('polygon soup').
