Jonathan, Thank you for your additional input. I am still trying to decide exactly how to proceed.
Steve -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Jonathan Egstad Sent: Wednesday, May 11, 2011 11:21 AM To: Nuke plug-in development discussion Subject: Re: [Nuke-dev] Bezier / Roto example code To soften Wouter's message - the Bezier node in Nuke has two parts, the node panel Knob UI which is tied to support code in Nuke itself, and the bezier rasterizer which is not and just uses DDImage. The Bezier Node's panel UI does have some customizations that requires the Qt toolkit (specifically the shape knob), but not all of the UI requires Qt. The popup menu gui in the Viewer is directly supported in DDImage so you can write custom Knob types that handle that level of UI plus arbitrary pickable OpenGL. Some of the custom node panel Qt stuff could be moved to knobs added to a Viewer strip in order to avoid Qt. The bezier rasterizer itself is straightforward and doesn't depend on any external libraries. It's unfortunate that the bezier support structures are not included in DDImage so they could be reused in other nodes and parts of the rasterizer embedded in DDImage for the same reason. Regardless of the method used to create the underlying bezier curve, DDImage itself should be able to rasterize a curve. This is one of the reasons why there's a general Render class in DDImage, though it never got extended to the point where it could rasterize non-polygonal primitives besides Points. Curves and Text were on the list... Wouter, my understanding is that the Qt license is supposed to be opened up in 6.3 to allow developers to write custom knobs that contain Qt widgets - is this not the case? If it is then it seems that the Bezier code falls into that category. -jonathan On May 11, 2011, at 10:37 AM, Wouter Klouwen wrote: > On 11/05/2011 17:49, Steven Booth wrote: > >> First, I really don't think that modifying the current RotoPaint node >> is feasible [..] the RP node was never designed [..] Making changes >> to it would imply [..] investment > > Very little is likely to change for 6.3 but there are plans for after that. > >> However, I would think that customizing and extending the old 'Bezier' node >> would be relatively easy, if the code was available, as it is for many of >> the other basic nodes. > > The old Bezier node is integrated into Nuke, the source of this Node > being available to you would be quite useless as you wouldn't be able > to compile it.
