Test data to load a boundary curve for FST Laplace solver
region of interest support
refactor ortho matrix setup to ISDrawable
ROI support
ROI support
Laplace filter for solving homogeneous boundary value problems. It has issues solving large buffers. It may be an issue with insufficient dynamic range of half floats. I will do more tests to confirm there isn't an issue with the underlying RFT.
Stub for absolute value drawable
This is not used anywhere yet. Vectorized 2 point, first stage butterfly. The assembly output is not of high quality. Use this as a prototype to create clean assembly code by hand.
Ignore Pods direction, invoke pod install at the command line to get the dependencies.
Added opencv as dependency.
Added ROI support.
Support types for ROI support.
Check pbuffer creation status. Moved glFinish into the pipeline. The glFinish is required for consistent access to a pbuffer.
I don't know the source of the problem. But, a texture dimension below 64 pixels cause problems with certain code paths. Sometimes they work, sometimes not.
Size for ROI
Remap drawable and tuple type.
Added 2D indexer. These are actually prefered as 1D indexers don't handle ROI easily.
Added a 2 tuple macro
Check framebuffer status
Set pbuffer boundary for solving boundary value problems. Has cubic interpolation capabilities for filling large buffers with lower resolution boundary curves
