Syntax

[domNode]=amfStruct2xml(amf,fileName,optionStruct);

Description

This function provides the basis for coding AMF files.

Example:

Create example mesh

[F,V]=geoSphere(2,50); %Faces and vertices
c=[1 0 0]; %RGB Color

volume1_Name='sphere';
material1_Name='sphere material';

cFigure;
title('Model to export to AMF')
gpatch(F,V,c);
axisGeom; camlight headlight;
drawnow;

Define file name

defaultFolder = fileparts(fileparts(mfilename('fullpath')));
savePath=fullfile(defaultFolder,'data','temp');
fileName=fullfile(savePath,'tempModel.amf');

Create AMF structure

% Define AMF units and version
amf.ATTR.unit='mm'; %Set units
amf.ATTR.version='1.1'; %Set AMF version

% Add optional metadata here
amf.metadata{1}.ATTR.type='name';
amf.metadata{1}.VAL='Sphere mesh';

amf.metadata{2}.ATTR.type='author';
amf.metadata{2}.VAL='GIBBON';

% object definition

%-> vertices
amf.object{1}.ATTR.id=1;
for q=1:1:size(V,1) %Loop over all vertices
    amf.object{1}.mesh.vertices.vertex{q}.coordinates.x=V(q,1);
    amf.object{1}.mesh.vertices.vertex{q}.coordinates.y=V(q,2);
    amf.object{1}.mesh.vertices.vertex{q}.coordinates.z=V(q,3);
end

%-> volume -> triangle
amf.object{1}.mesh.volume{1}.ATTR.materialid=1;
amf.object{1}.mesh.volume{1}.metadata{1}.ATTR.type='name';
amf.object{1}.mesh.volume{1}.metadata{1}.VAL=volume1_Name;

for q=1:1:size(F,1) %Loop over all triangles (note zero indexing hence -1)
    amf.object{1}.mesh.volume{1}.triangle{q}.v1=F(q,1)-1;
    amf.object{1}.mesh.volume{1}.triangle{q}.v2=F(q,2)-1;
    amf.object{1}.mesh.volume{1}.triangle{q}.v3=F(q,3)-1;
end

% material
amf.material{1}.ATTR.id=1;
amf.material{1}.metadata.ATTR.type='name';
amf.material{1}.metadata.VAL=material1_Name;
amf.material{1}.color.r=c(1);
amf.material{1}.color.g=c(2);
amf.material{1}.color.b=c(3);

Export xml

amfStruct2xml(amf,fileName);

zip file

[pathName,fileNameClean,c]=fileparts(fileName);
zipName=fullfile(pathName,[fileNameClean,'.zip']);
zip(zipName,fileName);
movefile(zipName,fileName);
