import_STL

Below is a demonstration of the features of the import_STL function

Contents

Syntax

[stlStruct] = import_STL(fileName);

Description

Use import_STL to import binary or txt type STL files.

Examples

clear; close all; clc;

Plot settings

fontSize=25;

Set path and file name

%Set main folder
defaultFolder = fileparts(fileparts(mfilename('fullpath')));
pathName=fullfile(defaultFolder,'data','STL');

%File name for STL
fileName=fullfile(pathName,'femur.stl');

Import a txt type STL file as patch data

[stlStruct] = import_STL(fileName);

Access the data from the STL struct

F=stlStruct.solidFaces{1}; %Faces
V=stlStruct.solidVertices{1}; %Vertices

In STL files nodes are not shared between triangles. Therefore the need to be merged with they are intended to be shared.

[F,V]=mergeVertices(F,V); % Merging nodes

Plotting the model

cFigure;
title('Imported patch data from STL','fontSize',25);
gpatch(F,V,'g');
axisGeom;
camlight('headlight');
lighting phong; axis off;
drawnow;

Import a binary type STL file as patch data

fileName=fullfile(pathName,'femur_bin.stl');
[stlStruct] = import_STL(fileName);

Access the data from the STL struct

F=stlStruct.solidFaces{1}; %Faces
V=stlStruct.solidVertices{1}; %Vertices

Merge nodes

[F,V]=mergeVertices(F,V); % Merging nodes

Plotting the model

cFigure;
title('Imported patch data from STL','fontSize',fontSize);
gpatch(F,V,'g');
axisGeom;
camlight('headlight');
lighting phong; axis off;
drawnow;
