Below is a demonstration for:

Contents

clear; close all; clc;

Syntax

[F,V,C]=import_obj(fileName);

Description

This function imports the geometry (faces and nodes0 contained in an OBJ file. All texture/material data is ignored.

Examples

defaultFolder = fileparts(fileparts(mfilename('fullpath')));
loadPath=fullfile(defaultFolder,'data','OBJ');

testCase=1;
switch testCase
    case 1
        modelName='gibbon.obj';
    case 2
        modelName='test.obj';
    case 3
        modelName='lego_figure.obj';
end
fileName=fullfile(loadPath,modelName);

objStruct=import_obj(fileName);

F=objStruct.F;
V=objStruct.V;
C=objStruct.C;
F_uv=objStruct.F_uv;
ij_M=objStruct.ij_M;
m=objStruct.m;

hf=cFigure;
subplot(2,2,1); hold on;
title('Texture image');
image(m);
axis tight; axis square;

subplot(2,2,3); hold on;
title('Geometry');
gpatch(F,V,'w','none');
axisGeom; camlight headlight;
drawnow;

hf=cFigure;

subplot(2,2,[2,4]); hold on;
hp=gpatch(F,V,C,'none');

axisGeom; %camlight headlight;
drawnow;

%Populate the animStruct

subdevMethod=2;

ns=[0 1 2 3];

nSteps=numel(ns); %Number of animation steps
animStruct.Time=linspace(0,1,nSteps); %Create the time vector
for q=1:1:nSteps

    [Fs,Vs,Fs_uv,ij_Ms]=subdevTexture(F,V,F_uv,ij_M,ns(q),subdevMethod);
    Cs=textureCoord2FaceColor(Fs_uv,ij_Ms,m,'face-center');

    %Set entries in animation structure
    animStruct.Handles{q}=[hp(1) hp(1) hp(1) hp(2) hp(2) hp(2)]; %Handles of objects to animate
    animStruct.Props{q}={'Faces','Vertices','FaceVertexCData','Faces','Vertices','FaceVertexCData'}; %Properties of objects to animate
    animStruct.Set{q}={Fs{1},Vs,Cs{1},Fs{2},Vs,Cs{2}}; %Property values for to set in order to animate
end

Viewing the animation. By calling anim8 a GUI is created in the specified figure. An anim8 scrollbar and buttons appear to interact with the animation. There is a play/stop button, a timing adjustment button, a bounce button, and an export gif button. Press the questionmark button to get help on these buttons.

Start anim8 gui

anim8(hf,animStruct);
