I'm trying to draw a small circle in a pwindow using gl.sketch. My 

pwdindow is 1000x750. My desktop resoultion is 1920x1200.

1 - To draw in the bottom-right corner, i have to send "moveto 1.1 

2 - How do i convert the mouse x y from the mouse/mouseidle function of 

a pwindow (it seems to be in pixels) to something i could use with the 

moveto message ? In other words, what is the screentoworld mechanism out 

Sorry to ask so basic questions, but i've been only a few times into 

XP SP2 / MaxMSP 4.6.3 / Jitter 1.6.3 (i guess, because it's the last zip 

i got on my desktop, but version infos on jit mxe's says 1.5.3.79...)

see screentoworld and worldtoscreen messages to jit.gl.render.

also experiment with enabling @ortho for the gl.render for "flat" rendering

with no z depth if you dont need it

Have you tried different scales for the pwindow, maybe only square ones have the full -1. to 1. range for XY. Or maybe they all have that, unless you set some flag (interp? not sure).

--2 - How do i convert the mouse x y from the mouse/mouseidle function of a pwindow (it seems to be in pixels) to something i could use with the moveto message ? In other words, what is the screentoworld mechanism out there ?

Seems like if it's static and only XY, you could just figure out the right scale object command for the pixels--> GL conversion.

Not totally sure about all this, just experimenting... :)

That was some good info and helped clear things up, thanks!
