How can I have users change textures in acrobat 3d and Reader question tia sal2

Question

I'm trying to have users in Acrobat reader change textures of a box which I made in acrobat 3d
how can I do this?
Example
I made three textures for a box and I would like the user to have the ability to change the textures if they choose. How can I do this? Any examples?
Can I have a user select the textures or the layers from a photoshop file in Acrobat 3d?

Yo ratboy,
You can do this. In order to map the images, they must be attached as a 3D resource. (There is a free plugin for this; search the forum for "Attach3DResource.api"). Once the images are attached, you can use the 3D Javascript API to map them to the meshes you desire.
For one doc, I attached 25 images in this manner. I then used the script below to create a bunch of empty meshes, and then apply the images to said meshes.
Hope this helps!
//3D javascript ========================================
//create 25 procedural meshes ======
var leftEdge = -180;
var horizontalOffset = leftEdge;
var verticalOffset = 0;
var myMesh = new Array();
var myVector = new Array();
for ( i=0; i<25; i++ ) { myMesh[i] = scene.createSquareMesh(64, 48, "myMesh" + i); myVector[i] = new Vector3( horizontalOffset, verticalOffset, 0 ); myMesh[i].transform.translateInPlace(myVector[i]); horizontalOffset += 74; if ( horizontalOffset > 180 )
horizontalOffset = leftEdge;
verticalOffset += 58;
//create image array and resource objs ============
var myImageResources = new Array();
var myImageFiles = new Array("8d91.jpg",
"ad2e.jpg",
"barnpond.jpg",
"Beach01.jpg",
"Beach04.jpg",
"Beach05.jpg",

//create resource objs
for ( i=0; i<25; i++ ) { myImageResources[i] = new Resource("pdf://" + myImageFiles[i]); }
//load images on meshes with handler ============
var myImageObjs = new Array();
var myImageMats = new Array();
myRenderer = new RenderEventHandler();
myRenderer.onEvent = function(renderEvent)
for ( i=0; i<25; i++ ) { //create image from resource myImageObjs[i] = new Image(myImageResources[i]); console.println("Image = " + i);
//add image to model
myImageMats[i] = myMesh[i].material;
myImageMats[i].diffuseTexture.setImage(myImageObjs[i]);
//remove handler
runtime.removeEventHandler(myRenderer);
runtime.addEventHandler(myRenderer);
//cause a recalculation of the scenegraph.
scene.update();
console.println("Call scene.update()");
console.println("Created 25 Square meshes: (64, 48, 'myMeshN')");
