hi all,

i'm using the vex ring to create some pattern, please see the follows, http://farm3.static.flickr.com/2411/2048808743_293ab165b1_o.jpg [farm3.static.flickr.com]
however, i want to make the ring size varies in a gradation from small to
large. any expressions to use for the vex at the ring size input?

also, if i want to flip the image 90 degree or 45 degree, what vex shall i
use??

thanks.

cheers herman

hello again Herman,

To get the rings to go from small to large, bring in the global variables vop and plug the x value into the dotsize parameter.
This should give u rings that get larger from left to right.
To give you more control, just add a multiplier.

hi tim, great it works!! many thanks!

so how do we rotate the images/objects?

say i use the strips, the default is vertical, how to rotate into horizontal?

appreciate ur prompt answer again!

cheers herman

There's a transform node in cops that allows you to tranasform the image. Just put this at the end of your network and you can rotate till your hearts content.

hi tim,

thanks again for the reply, i'm under vex/cop filter/ cos i want to transform at there… i tried with the transform node there before but seem not to work, there is only from/to in that node.
my procedure as such-

ring(amount)>float to vector>(from)transform(in)>output (r,g,b)

attached is the image for your review.

many thanks.

cheers herman
