STL File Reader

by

 

11 Dec 2008 (Updated )

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

File Information
Description

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
object.

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?

i think this gives wrong faces? Please confirm.

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.

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.
