Hi everyoneI need to create a grid in GEM in which i can control each node independently. I tried using [curve3d] but the transposition of one node affects its neighbors (as this object is intended to work). What i need is something that would be capable of creating some sort of histogram, where each node can take a Z value independently.  I guess that if i use [curve] and use the resolution equal to the number of nodes i could achieve the effect, but i would be dealing with many independent entinties and would have to duplicate them to achieve the orthogonality of the mesh.

Try [gf/gl] from GridFlow. It can integrate well and it's message-based instead of object-based, which means that making custom geos such as what you want can be done by sending some simple messages, without need for [repeat] nor complicated nets of [GEMglVertex3f] objects with lots of [+] and [-] and [*] around.

First, you send a "begin quads" message and then a number of "vertex $1 $2 $3" messages using [until] or [for] or [foreach] or whatever other means of looping you have. No need to care for routing what comes of [gemhead], you don't need it (just convert it to a bang using [b]). Don't forget to send an "end" message at the end of the shape.
