solved Dynamic Texture as GUI Image

[Pryme8]

Is it possible to pass a texture, a dynamic texture, or even better a material to a GUI button?

I know I could convert the texture to an image, but I was hoping to skip a step.

texture.update()
            
            /*-- Create Image --*/
            var canvas = document.createElement('canvas')
            canvas.width = size.x, canvas.height = size.y
            
            var tCtx = canvas.getContext('2d')
            var iDat = ctx.getImageData(0,0,size.x, size.y)
        
            tCtx.putImageData(iDat, 0,0)
            
            var image = new Image()
            image.id = "GUI-Image"
            image.src = canvas.toDataURL()
            
            texture.rawImage = image;


Is what I am doing right now.

Ideally I would want to be able to assign a rtt, to a Image on a button on the GUI.  With the intent of raymarching some GUI elements but using the GUI's structure to organize and deal with mouse interaction.

GUI is canvas based so there is no webgl involved. So no material or texture.

So you need to read pixels (texture.readPixels) and use that to draw in your canvas. Should not be a problem if you don't that too much as it involves GPU->CPU memory transfer

thanks what I was kinda thinking!
