Hello,

Is it possible to somehow use fillText() to place a text onto previously loaded texture?
I have a code like below:

function onStartClick( ) {
    if (changed == 0) {
        var material = new THREE.MeshBasicMaterial( { map: THREE.ImageUtils.loadTexture( 'TexPudelko_Changed.jpg' ) } );            
            //  material.fillText();
    changed = 1;
    }
}

It dynamically changes the texture of the object if user clicks on some div object.

But i would like to add a text on the defined position into this texture too.
Can I do that only with Three.JS and how if so?

Thanks for help.
PJ

Just create a normal canvas and do this:

var texture = new THREE.Texture( canvas );
texture.needsUpdate = true;

var material = new THREE.MeshBasicMaterial( { map: texture } );

Then for modifying the canvas, do this:

texture.image.getContext('2d').fillText(); // or directly use a context reference if you already have it
texture.needsUpdate = true;

I already did it in similar way several minutes after my post. Thank you anyway :)
