4 Major Enhencements

[Asnly1]

Here is a summary of the new features:

1. Matrix-Driven Camera Mode

• This new mode allows rendering a dataset (train/test) directly from a transforms.json file with same format in your original implementation.
• It automatically restores camera poses and intrinsics, making it possible to re-render scenes from existing camera trajectories.

2. Multi-Channel Data Export

• The rendering pipeline has been re-engineered to simultaneously export multiple data channels.
• Users can now enable checkboxes in the UI to export:
  • RGB (.png)
  • Instance Mask (.png)
  • Depth (.png and .exr)
  • Normals (.png and .exr)

3. Expanded Camera Paths for COS Mode

• The "Circle on Sphere" (COS) mode has been extended with more camera path options:
  • Spherical Spiral Trajectory: Smoothly covers both the upper and lower hemispheres.
  • Multi-Level Horizontal Orbits: Allows capturing images at several distinct height levels, simulating common drone capture patterns.

4. Workflow & Quality-of-Life Improvements

• Test Set Consistency: The transforms_test.json generated by SOF/TTC/COS modes can now reuse an existing matrix file, ensuring consistent test sets across different training data acquisitions.
• Enhanced Logging: Log files now include the full camera intrinsic matrix for easier debugging.
• Optional Dataset Compression: Users can choose to automatically compress the dataset into a .zip file and delete the raw image folders upon completion.
