hello,

i'm working on a project and need some advice. in the gem_movie.pd, the example has the movie file textured onto the <cube> object...in a version of the same project i'm working on, i used the <square> object onto which my file is textured. However, ideally, i'd like the movie to retain its shape. in the current version i'm working on, i have the <pix_movie> object connected to a <polygon> with an argument of <4>. the x y z coordinates are assigned so that z = 0. the problem is that when i render, i can't get anything to show up on the screen. what am i doing wrong? i'm including the video section of the program. any help is greatly appreciated.

i think the way you are treating coordinates is a little bit confused... in your demo you create a window that is sized 600*400 PIXELS. then you are using these numbers (600, 400) as arguments for your polygon, which will definitely produce something you don't want (ever tried tor create a square with a dimension of 600 ? - a little bit huge...i will mostly use sizes of 1 to 4) when you change the points of your polygon to range below 10 (scale it by 1/200 that's 3 for 600, 2 for 400) you will (hopefully, though i am not very sure) get what you want

also, is there a way to create a CASE like statement in pd? i'm using <moses> at the moment, and it seems awfully clunky.

that was bothering me too, but i do think there are elegant solutions using relational-operators (in the case of an exact "case" just use "==") and "select"
