Hey Chris,

On the topic of vertex arrays and how to deal with all that data... I just had an idea for a vertex array controller. Basically its a grid of values, or pixels. (This could be implimented in tcl/tk, or in openGL, but GLUT sounds like a problem). The creation arguments are the width and height of the grid, perhaps also how big it apears in the patch, or whatever. You can change the values of the pixels by clicking and dragging up and down (just like a number box) or perhaps you could draw one pixel at at time. There would also be objects to load image-files into these grids, which the can be controlling the vertex array. It would be very nice to use pix_ data in these controllers, and very interesting if you could load live video, QTs into them. These arrays would be storing 3D data, so you would have to use multiple layers/channels to get really complex stuff going.

The seed idea I guess is to control a vertex array with the values in a small (maybe) pix_ buffer. then you can control the vertex array via pix_ objects, and maybe also do some hand control as well.... (via the vertex array controller object) Of course we would need a fast gui... Maybe the controller would have to be openGL itself.. (but then what about the mouse positions? SDL gives GL wrapping and mouse position data and it is cross-platform...

Anyhow there is the creative moment of the day.

It should be possible with the vertex_array stuff. I just saw a demo of Luxology's forthcoming 'modo' and it converted free hand drawing into tubes. While GEM might not do anything that fancy very soon, a similar idea could be made into an object. Each new point input into the object would be a new vertex and jumping between points would result in more minear structures. It would be easy to use this with something like Yves' grid object. I'm not sure about getting position info from the gemwin and having it consistant across platforms without using GLUT for everything.

Hmmm, sounds good Yves!

I wonder if anyone has done something similar for Gem? I would like to draw masks over video in realtime. So this pen tool should include an algo to fill in the object being drawn...

Any thoughts?

Thanks Ben

hi,

0.12.8 added pdp_pen : a free hand drawing object ( on request from patrick )

cheers, sevy
