Summary

This PR implements preview image and video rendering features as specified in #5 and #6.

Changes Made

Preview Images (Issue #5 - \ USD)

  1. *New file:
    ender_preview_images.py*

    • Reads the PLY file to compute bounding box and centroid
    • Generates camera paths for top-down and angled views
    • Renders preview images using nerfstudio's
      s-render\ command
  2. *Modified:
    un.py*

    • Added preview rendering step after Gaussian Splat conversion
    • Implemented as best-effort operation (non-fatal if rendering fails)
  3. *Modified: \server/rust/runner/src/lib.rs*

    • Added logic to upload preview images as domain artifacts
    • Preview images uploaded with \data_type: splat_preview_image\

Preview Video (Issue #6 - \ USD)

  1. *New file:
    ender_preview_video.py*

    • Generates a 360° orbital camera path at 35° elevation
    • Renders frames using nerfstudio's
      s-render\ command
    • Encodes frames to MP4 using ffmpeg with web-friendly settings
  2. *Modified:
    un.py*

    • Added preview video rendering step after preview images
  3. *Modified: \server/rust/runner/src/lib.rs*

    • Added logic to upload preview video as domain artifact
  4. *Modified: \README.md*

    • Documented all new preview outputs

Output Files

\
{job_root_path}/refined/splatter/
├── preview_top.png # Top-down view preview
├── preview_angle.png # Angled 3/4 view preview
└── preview.mp4 # 360° orbital preview video (5 sec at 30fps)
\\

Technical Details

  • Preview Images: Two static views (top-down and angled 3/4)
  • Preview Video: 360° orbit at 35° elevation, 5 seconds (150 frames at 30fps)
  • Resolution: 1920x1080 (configurable)
  • Video Encoding: H.264 with CRF 23, web-friendly flags

Acceptance Criteria

  • Two preview images are rendered: top-down and angled 3/4 view
  • Preview video (MP4) is rendered with smooth orbital camera path
  • All outputs are saved to correct output directory
  • All outputs are uploaded to domain as artifacts
  • Preview rendering is best-effort (non-fatal)
  • README documentation updated

Bounty Claims

Please update the Docker file to include the newly added scripts and do an end-to-end test by building a Docker container and sending a rendering job to it. If successful, the previews should be uploaded to the Auki domain. Please download the generated files from the domain and attach them here. I'll review again after the fixes are uploaded and the PR is rebased.
