Roto Node curves colors #31

Closed blackearth2014 closed 10 years ago

blackearth2014 commented 10 years ago

Can the roto node curves have colors for the their closed splines instead of using the constant node to apply colors and its outline. When Autodesk Combustion was active, they had a operator feature called G_Buffer_Builder that allow you to draw curve splines around objects in the scene. These curves could be shaded a range of greyscale to generate a fake z-depth pass. Once all the curves were painted, you could then apply the G-Buffer operator to simulated depth of field. When you add a the blur node, it would be nice if the blur node can generate these types of shallow depths of field effects. Photoshop has a lens blur effect that can do the same thing. In Gimp it is called focus blur.

Also it makes it easier to identify what you have previously rotoed without have to type the names for every curve.

Attached is the process of how I do it in GIMP. I think a lens blur node, or bokek blur, or defocus node would be a welcome addition.

I think there are already OpenFX plug-ins doing this kind of thing

Thanks for the link. The OpenFX plugin cost more that the other API platform plugins. Why is that?

MrKepzie commented 10 years ago

I have no idea. We're not connected in any way to the developers of these plugins.

Can the curves still get individual closed spline colors in following after the next update.

When you say closed spline colors, do you mean like shape layers in After Effects? http://sketchpetstudios.files.wordpress.com/2013/10/screen-shot-2013-11-04-at-10-48-01.png

Yes. Sorry I was using some 3D open source program forum term.

Here you go, roto shapes now have custom colours that can be blended together with compositing operators: https://github.com/MrKepzie/Natron/commit/abad16cbcfc8b7eafc3563e49c4de7569832030a
