New nodes:
- Cubemap (3x2) → Equirectangular: Convert cubemap atlases back to equirectangular
- Equirectangular Mirror/Flip: Horizontal/vertical flip with proper spherical wrapping
- Equirectangular Resize: Smart resize with 2:1 aspect ratio preservation
- Equirectangular Rotate (Preset): Quick preset rotations (front, back, left, right, up, down)
- Cubemap Faces Extract: Export all 6 cube faces as separate images
Improvements:
- Enhanced tooltips for better user guidance across all new nodes
- Updated README with comprehensive documentation of new features
- Added processing methods to EquirectangularProcessor module
Technical details:
- Cubemap-to-equirectangular uses face sampling with bilinear interpolation
- Mirror/flip operations use numpy flip operations for efficiency
- Resize maintains standard 2:1 equirectangular aspect ratio by default
- Preset rotations map to common viewing angles with offset adjustments
- All nodes support batch processing and multiple interpolation methods
- Embed rotation/crop/interp controls in Equirectangular Processor node (optional inputs, defaults)
- Add node/param tooltips and node descriptions across all nodes
- Rewrite README with updated usage, node overview, and installation notes
- Include tests/run_node_smoke_tests.py for local sanity checks
- Add crop_to_square function that crops width to match original image height
- Create dedicated EquirectangularCropSquare node for square cropping
- Add crop_to_square option to combined processor node
- Change default pitch rotation from 0° to -65° across all nodes
- Square crop takes precedence over 180° crop when both are enabled
- Perfect for creating square images at original height resolution
