It is possibile to create a texture (to use on a element in a canvas) from the getImageData array of another canvas (in the same html page)? maybe without three.js? Thanks a lot
Thats the point of getImageData, getting an image to manipulate it and then draw on any canvas.
imageData = someContext.getImageData(0, 0, canvasWidth, canvasHeight);
anotherContext.putImageData(imageData, 0, 0);
doing things like: http://jsfiddle.net/jaibuu/myRGr/
If you don't intend to do pixel manipulation, you should only use drawImage(), without getImageData/putImageData which are slower though.
