JérômeM,

You can use a JavaScript to change many aspects of the material properties (including textures) at runtime such as scale, rotation, offset, etc.

Specifically what did you have in mind?

I can create 3D pdf file (i'm not using Acrobat 3D or other Adobe products, it's my own software) and I'm looking for a solution to change the texture with javascript.

Could you give me an example or a document which could help me ?

thx a lot.

HI Grayson,
In your attach3dresource website. Step 10. Select the menu item: Advanced > 3D > Attach Resource to 3D Annotation.

3D is not an option under the Advanced Menu tool. I have the API in the correct location - any thoughts to get it to be visable?
Thanx
Garry

Hi Grayson, When I work through your example - it works like your demo - however your demo has a bump map included, even when I include that file the bump map does not appear in the final Acro 3D. Any ideas?

PS: Are you sure we can't talk you into publishing a cool Acro 3D tutorials? I purchased the Acrobat 3D classroom in a Book - to have the book spend 80% of it's time telling about the interface icons and limited time on the cool parts.
gazzzz

I'm actually in the process of developing tutorials right now. They'll be going up on my site this week. Check http://www.graysonlang.com/acrobat3d/ later on.

This weekend I was busy working with the Wii remote. I'm attempting to write a plug-in to have it manipulate 3D objects in Acrobat. That will also be posted as a tutorial.

Hello grayson,
I wanted to thank you for that tutorial you wrote.
Now I´m able to assign maps which normally get lost during importing procedures(without any knowledge of javascript btw).
Regards, chuck

Is there any example of how to set a texture of 3DModel through Javascript?

I tried following but I always get "Resource is not defined" error:

// Create a new Resource with the file's URI as the argument
modelResource = new Resource( "pdf://sphere.u3d" );

// use Scene method "addModel" with Resource as an argument,
// returns top level node from loaded 3D file
model = scene.addModel( modelResource );

// Create a new Resource with the file's URI as the argument
imageResource = new Resource( "pdf://grid.jpg" );

// use the Image constructor with the Resource as an argument,
image = new Image( imageResource );

// set the loaded 3D model's diffuse texture to the image
model.material.diffuseTexture.setImage( image );

// loading of resources can be inlined if they are only used once
bump = new Image( new Resource( "pdf://knurl.jpg" ) );

// set the loaded 3D model's bump texture to the image
model.material.bumpTexture.setImage( bump );

I have the same problem, i cant change the material texture of my 3D object.

I see in the documentation JS 3D that this function setImage is deprecated

here is my code above, I want to change the texture of the mesh material which is called "ground"

txResource = new Resource("pdf://toto.jpg");

txImage = new Image(txResource);

mshMatl = scene.meshes.getByName("ground").material;

mshMatl.diffuseTexture.setImage(txImage);

anynody know how to change the material texture by a file ressource ?

thanks

regards

Simply set the old image object to be equal to the new one. In the context of your 3D scene:

var _mat = scene.meshes.getByName( 'ground' ).material;

var _tex = new Image( new Resource( 'pdf://tot.jpg' ) );

_mat.diffuseTexture.image = _tex;

Hi

thanks for your response

Unfortunately this does not work

i have integrated the picture toto.jpg in the pdf resource file

and I have integrated this code into a file. js :

var _mat = scene.meshes.getByName( "ground" ).material;

var _tex = new Image( new Resource( "pdf://toto.jpg" ) );

_mat.diffuseTexture.image = _tex;

in the console debug appear on line 3 (_mat.diffuseTexture.image = _tex;) :

"Code: 45(0x2d): Object is invalid"

I specify that this 3D mesh ground contains an textural material already existing in the U3D file

an idea about this problem please ?

thanks for your help

There's nothing wrong with the code in your last reply. Without seeing the file, all I can assume is that the names you're using are wrong. Does the node 'ground' exist in the model tree?
