[possible bug] touch message for jit.phys.picker with ortho camera
Oct 13 2015 | 11:06 pm
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.

- Oct 19 2015 | 4:31 pmhi spa, can you provide a simple patch demonstrating this?
- Oct 20 2015 | 1:00 amHere it is. By the way, could we get 'output_positions' even if dynamics=0? and for touch too?I think i remenber that screenraytest has the same problem...

- Oct 24 2015 | 2:52 amThanks for looking at it. 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
