<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I need to blob track a point of light in a video and use it to draw<br>
freehand in the GEM window, possibly mixed with previously-recorded<br>
video clips. I'd also like to connect the adjacent points with lines<br>
so that the drawing is continuous.<br>
<br>
I'm still pretty new to GEM, but I'm working on getting my head around<br>
all the render order and buffering ideas, I'm just not sure what the<br>
best approach is. I've tried using gemframebuffer going to a pix_snap,<br>
but it takes up 100% CPU, so I figure there's got to be a better way.<br>
Is there some sort of way I can just keep appending vertices to a list<br>
and use something like [curve]?<br>
<br>
Thanks,<br>
