I've made a GUI prototype fuse to propose some ideas, some clearly inspired by Nuke's corner pin. The Fuse doesn't transform an image (currently I'm lacking the OpenCL skills to implement a speedy image transformation) but draws some rectangles instead so you can play around with it. Some things I'd like to see in a corner pin can't be done by Fuses. But it's just a semi-finished idea for a tool anyways.
- The tool allows you to define source corners so you don't need to use the icky perspective positioner
- Allows you to easily define a reference frame for a four-corner-track by copying from destination to source coordinates and vice versa
- Fine-tuning offset sliders allow you to tweak the track or adjust it for the second eye in a stereo project. This is something Fusion's current corner positioner has already and I wouldn't want to miss it.
There are two versions of this fuse now. Both have 5x subsampling in CPU and OpenCL.
v1.0 is for Fusion 6.31 and up. It fully supports DoD and RoI.
v0.95 has partial DoD support for earlier versions of Fusion (you need at least Fusion 6.2 build 897). The input DoD is kept/transformed, but the Fuse will always request the full upstream image and clip what's outside its borders.
