Plenoxels: Radiance Fields without Neural Networks

Abstract: We introduce Plenoxels (plenoptic voxels), a system for photorealistic view synthesis. Plenoxels represent a scene as a sparse 3D grid with spherical harmonics. This representation can be optimized from calibrated images via gradient methods and regularization without any neural components. On standard, benchmark tasks, Plenoxels are optimized two orders of magnitude faster than Neural Radiance Fields with no loss in visual quality.

• The paper outlines a structured process for author rebuttal submissions that addresses reviewer comments without introducing new experimental results.
• It specifies strict formatting guidelines, including a one-page, two-column layout with defined margins and font sizes, to ensure clarity and consistency.
• The document emphasizes maintaining author anonymity and factual accuracy to streamline the review process and uphold academic integrity.

Guidelines for Author Rebuttal Submission

This document provides guidelines for authors on how to properly prepare and submit a rebuttal to reviewers' comments after receiving reviews for their submitted papers. The rebuttal process, as outlined, is a structured and standardized method followed in many academic conferences, such as CVPR.

Purpose of Rebuttal

The primary objective of the author rebuttal is to address factual errors, clarify concerns raised by reviewers, and provide additional information if requested by the reviewers. Importantly, the rebuttal is not intended to introduce new contributions that were not present in the original paper submission. Authors can include figures, graphs, or proofs to better support their responses if necessary.

Key Guidelines

There are several specific formatting and content guidelines authors must adhere to when preparing a rebuttal:

1. Length and Format:
   • The rebuttal must be limited to one page.
   • Content should be presented in two columns with defined margins.
   • Text should utilize 10-point Times Roman font for the main body and 9-point for figures and tables.
2. Content Restrictions:
   • No new contributions such as theorems, algorithms, or experimental results should be added unless specifically requested by reviewers.
   • Authors should not perform or report new experiments unless explicitly asked to do so.
3. Anonymity and Citation:
   • The rebuttal must maintain the anonymity of the authors.
   • No external links that reveal the author identity are allowed.
   • References should be included in a 9-point font and cited appropriately within the text.

Practical Implications

The rebuttal process is designed to streamline the review process, ensuring that responses are concise and purely focused on addressing reviewers' specific queries and factual inaccuracies. This limits the potential burden on reviewers and maintains the integrity and feasibility of the review process.

The restriction against adding new experiments or contributions helps to prevent scope creep and ensures that all substantive contributions are evaluated within the main submission, maintaining a fair and standardized evaluation process for all papers.

Theoretical Implications

From a theoretical standpoint, the rebuttal guidelines emphasize clarity and focus in scholarly communication. By adhering to these guidelines, the process fosters a disciplined approach to academic discourse, where authors must clearly justify and elucidate their original contributions without introducing extraneous variables post-submission.

Future Considerations in AI Research

In the field of AI research, precise guidelines for rebuttal submissions will continue to play a crucial role in managing the increasing volume of submissions to leading conferences. As methodologies and technologies evolve, it is conceivable that further refinements in rebuttal processes could include more interactive and dynamic forms of feedback, perhaps leveraging AI tools for preliminary rebuttal evaluations.

Moreover, the constraints on introducing new results during the rebuttal phase underscore the importance of comprehensive initial submissions. This may drive researchers to adopt more rigorous and exhaustive validation and documentation practices when preparing their initial manuscripts.

Conclusion

The document succinctly outlines a structured approach for preparing and submitting author rebuttals in response to paper reviews. By enforcing a set of well-defined formatting and content rules, it aims to make the review and rebuttal process as effective and efficient as possible, ensuring that responses are strictly focused on addressing reviewers’ comments. These guidelines not only facilitate a smoother review process but also uphold high standards of scholarly communication in the field of computer science.
