Release Type:
Beta
Version:

Release Notes
This update to GLTools adds in a Grid Generator and Renderer. Unlike the GLSL Grid patch, you are free to modify the vertexes on the generated grid directly. It's a little difficult to understand at first, so I'll probably make a demo composition shortly.
Installation InstructionsPlace the plugin file in 
A set of patches for drawing GL primitives and modifying the GL environment. Source code is available on GitHub. CreditsLogo by @usefuldesign.au. Known issues

Here's a demo composition and screenshot.

the U and V coordinates may get messed up in the demo composition (and may get messed up in normal usage too?) -- I'll try to fix that.
I'm thinking about making the structure generator save its state too, so you can continue editing it at a later time. How do y'all feel about this?
State saving is overkill....
Thank you so much, now I can have a quad display of my grid, and it still works within my displacement shader...
These Patches are very promising. I have some problem with point selection. Perhaps I don't understand how it works : I can select a point with mouse (left clic) ...but the point does not stay at his new place when I release the left button (I have a wacom tablet and losed the original apple mouse, perhaps a bug with this... )
yanomano.
You have to trigger the "Commit Changes" input for the modification to stick. It's a weird interface, but it was the best I could do at the time :) This allows you to see how a modification would look, without committing to it (free undo, in a weird way)
In my demo composition, commit is tied to a right-mouse click which my not be possible with a tablet... maybe bind it to a keyboard key?
