标题： Poxel: Voxel Reconstruction for 3D Printing

摘要： 最近在3D重建方面的进展，特别是通过神经渲染方法如神经辐射场（NeRF）和Plenoxel，已经实现了高质量的3D可视化。 然而，这些方法是为数字环境优化的，并使用视图依赖的颜色模型（RGB）和2D splatting技术，这在物理3D打印中效果不佳。 本文介绍了“Poxel”，即可打印体素，是一种针对光聚合喷射3D打印优化的基于体素的3D重建框架，该框架使用CMYKWCl颜色模型，可以生成高分辨率、全彩色的3D模型。 我们的框架通过消除视图依赖性并将数字RGB颜色空间转换为适用于多材料喷射的物理CMYKWCl颜色空间，直接输出可打印的体素网格。 所提出的系统在打印模型中实现了更好的保真度和质量，符合物理3D物体的要求。 显示英文摘要

摘要： Recent advancements in 3D reconstruction, especially through neural rendering approaches like Neural Radiance Fields (NeRF) and Plenoxel, have led to high-quality 3D visualizations. However, these methods are optimized for digital environments and employ view-dependent color models (RGB) and 2D splatting techniques, which do not translate well to physical 3D printing. This paper introduces "Poxel", which stands for Printable-Voxel, a voxel-based 3D reconstruction framework optimized for photopolymer jetting 3D printing, which allows for high-resolution, full-color 3D models using a CMYKWCl color model. Our framework directly outputs printable voxel grids by removing view-dependency and converting the digital RGB color space to a physical CMYKWCl color space suitable for multi-material jetting. The proposed system achieves better fidelity and quality in printed models, aligning with the requirements of physical 3D objects.
