Tracing Geometry with an Alpha Channel? I have not used a forum before to get an answer for a technical question, so bear with me.
also, my spelling is pretty bad :)
ok so,
I have an alpha channel for a logo that I want to animate. I want the logo to have depth. as in not just the flat image plane but extruded.

is there a way to cut out the logo from the image plane using the alpha image to manipulate the geometry?
ideally, there would be a way to have a blender automatically place edges around the edge of the logo so that I can just delete the parts that aren't needed.

any solutions???
For a logo trace it in a vector drawing program and export it as SVG.
No need to deal with alpha or pixels.
