It seems that the touch message got Y inverted when ortho=1 or 2 for the camera.

Directly picking in the window works correctly.

but sending the same coordinates with touch is Y inverted.

I know there's in OpenGL something about the inverted matrix transform with ortho view.

I suppose it's not considered with the touch message.

Well after some experiments, it seems that touch messge is buggy also with a 'normal' camera.

The vertical position of a touch is offseted.

This offset becomes biggger the wider the camera angle. ???

Strangely, horizontal position does not seems affected.

Check the forums for something like " world to screen "

hi spa, can you provide a simple patch demonstrating this?

By the way, could we get 'output_positions' even if dynamics=0?

I think i remenber that screenraytest has the same problem...

Here it is.

and for touch too?

yeah, i can see some issues here. thanks for the patch, i'll see what i can do to fix this.

It becomes a "big" problem when using nested compositions with jit.gl.node.

The offsets adds... particularly with rotation of ctx.

I'm develloping a multitouch app and it makes impossible to use jit.gl.node. :(

Do you imagine solving it soon, or should I just work around it?

Thanks for looking at it.
