STL File Reader

STLREAD imports geometry from a binary stereolithography (STL) file into MATLAB.

File Information

In addition to the STLREAD import function, this submission also includes a small demo that loads an STL model of a human femur bone.

FV = STLREAD(FILENAME) imports triangular faces from the binary STL file
indicated by FILENAME, and returns the patch struct FV, with fields 'faces'
and 'vertices'.

[F,V] = STLREAD(FILENAME) returns the faces F and vertices V separately.

[F,V,N] = STLREAD(FILENAME) also returns the face normal vectors.

The faces and vertices are arranged in the format used by the PATCH plot

This function is for binary STLs only, and will cause problems when used with ascii STL. The conditional statement against reading ascii STLs is commented out.

what is meant by faces and vertices?

I want to generate a 3D-array out of my STL-files.. is there a way?

Memory expensive, the script quickly crash because the computer is out of memory. The script extract about a billion points from my STL files. From my calculation, I would need about 100 Gb of ram......

Does someone have a solution for this problem?

Thanks for your submittal. What units is the model in once I've read the stl file with Matlab. I am using NextEngine's 3D scanner and they are telling me that the units are defined by the reader utility.

Very nice and useful.

I have re-written this function to be much faster.

Very useful for binary filesl but do not support ascii format

very useful!

can the vertices and faces be arranged such that they can be used with surf??

textures cannot be applied to patch objects. surf is more useful.
