How to get all coordinate
What steps will reproduce the problem?
1. I have a obj file exported from blender,How to get all the
vertexBuffer,indexBuffer,texCoordBuffer,texCoordIndexBuffer.
2. I have attached the obj file.
3.
What is the expected output? What do you see instead?
What version of the product are you using? On what operating system?
Please provide any additional information below.

First of all, you should get the obj file loaded in the viewer. When done, the
content of the obj file are wrapped in a Scene object, which can be obtained
via the viewer.getScene()
method(http://jsc3d.googlecode.com/svn/trunk/jsc3d/docs/symbols/JSC3D.Viewer.htm
l#getScene).
An obj model might be parsed to multiple meshes, you can get this mesh array
using scene.getChildren()
method(http://jsc3d.googlecode.com/svn/trunk/jsc3d/docs/symbols/JSC3D.Scene.html
#getChildren).
Now that you have all the mesh objects, the primitive data are merely plain
properties of these meshes which can be accessed at your will:
mesh.vertexBuffer
mesh.indexBuffer
mesh.texCoordBuffer
mesh.texCoordIndexBuffer
...

Thanks for reply,but viewer.getScene() returning null,please check the coding
below,is anything wrong?
var canvas = document.getElementById('cv');
var viewer = new JSC3D.Viewer(canvas);
viewer.setParameter('SceneUrl', 'bank/female02.obj');
viewer.setParameter('InitRotationX', 0);
viewer.setParameter('InitRotationY', 0);
viewer.setParameter('InitRotationZ', 0);
viewer.setParameter('MipMapping', 'on');
viewer.setParameter('Renderer', 'webgl');
viewer.init();
viewer.update();
var scene = viewer.getScene();
alert(scene);

The loading is asynchronous. So you should override the
viewer.onloadingcomplete(http://jsc3d.googlecode.com/svn/trunk/jsc3d/docs/symbol
s/JSC3D.Viewer.html#onloadingcomplete) with a callback function and wrap your
code in it like this:
var viewer = ...
...
viewer.init();
viewer.update();
viewer.onloadingcomplete = function() {
// This will be executed immediately as the loading is done.
var scene = viewer.getScene();
console.info(scene);
...
};

Ok thanks for your reply,can u please tell me how to load multiple obj file?

This discussion http://code.google.com/p/jsc3d/issues/detail?id=52 provides a
good example for how to load multiple models into a single scene.
Please be aware that mutiple models from different sources can be used in a
scene only if they share the same model space. Otherwise there will be a mess.

How to Change texture of a mesh on a button click?
Original comment by [email protected] on 25 Jul 2014 at 10:07
First, get the clicked mesh via mouse event handlers. Then invoke
mesh.setTexture()
method(http://jsc3d.googlecode.com/svn/trunk/jsc3d/docs/symbols/JSC3D.Mesh.html#
setTexture) passing in a new texture object to replace the old one. Finally,
call viewer.update() to notify the viewer the scene has changed and update
display. The programming interface of JSC3D.Texture is documented here
http://jsc3d.googlecode.com/svn/trunk/jsc3d/docs/symbols/JSC3D.Texture.html.

How to change vertexbuffer of a mesh on a button click?
Original comment by [email protected] on 30 Jul 2014 at 10:46
Don't change vertexBuffer of an existing mesh. Create a new mesh with the given
vertices and use it to replace the old one.
