Introduction​

Postshot is a tool for creating Radiance Fields, including NeRFs and Gaussian Splats. It is designed to be a user-friendly solution for generating high-quality 3D representations from images.

Documentation for Methodology​

To ensure your work aligns with the Berkeley Protocol and the Guide for Judges, use the following points to document your use of Postshot.

Methodology: How to document Postshot

In Your Method Section​

Guidance: Describe the purpose, the tool version, and the input data.

  • Investigative Objective: To generate a Radiance Field representation (NeRF/Gaussian Splat) for novel view synthesis and visualization.
  • Software Version: Postshot [Version] (e.g., 0.5).
  • Input Data: Derived from [Video/Image Set Name] (Source Hash: [First 6 digits]).

In Your Decision Log​

Guidance: Record the specific procedural parameters and integrity checks.

  • Specific Settings: Model Type (Gaussian Splatting/NeRF), Training Iterations ([Number]), Resolution ([Width]x[Height]).
  • Assumptions: Assumed consistent lighting throughout the capture and a static scene.
  • Integrity Check: Verified that analysis was performed on a working copy, not the original evidence file.
  • Date Performed: [YYYY-MM-DD].

Verification & Mitigation​

Guidance: How did you mitigate bias or verify accuracy?

  • Verification: Visually compared generated novel views against original source images for artifacts or hallucinations.
  • Bias Mitigation: Ensured training data covered a wide range of angles to prevent overfitting to specific viewpoints.

Common Limitations​

  • May generate visual artifacts ("floaters") in areas with few observations.
  • Does not produce a topologically clean mesh by default; geometry is implicit or point-based.

Example Methodology Statement​

"To visualize the environment from novel angles, Postshot (v0.5) was used to train a Gaussian Splat model from the input video [Hash: D4E5F6]. The model was trained for [X] iterations assuming a static scene. The resulting visualization was verified against source frames to ensure no significant visual artifacts were introduced."
