Relational Anatomical Supervision for Accurate 3D Multi-Chamber Cardiac Mesh Reconstruction
Chenyu Zhang, Yihao Luo, Lei Zhu +3
Accurate reconstruction of multi-chamber cardiac anatomy from medical images is a cornerstone for patient-specific modeling, physiological simulation, and interventional planning.…
Faithful Contouring: Near-Lossless 3D Voxel Representation Free from Iso-surface
Yihao Luo, Xianglong He, Chuanyu Pan +7
Accurate and efficient voxelized representations of 3D meshes are the foundation of 3D reconstruction and generation. However, existing representations based on iso-surface heavily…
Sparc3D: Sparse Representation and Construction for High-Resolution 3D Shapes Modeling
Zhihao Li, Yufei Wang, Heliang Zheng +2
High-fidelity 3D object synthesis remains significantly more challenging than 2D image generation due to the unstructured nature of mesh data and the cubic complexity of dense volu…
MeshAnything V2: Artist-Created Mesh Generation With Adjacent Mesh Tokenization
Yiwen Chen, Yikai Wang, Yihao Luo +5
Meshes are the de facto 3D representation in the industry but are labor-intensive to produce. Recently, a line of research has focused on autoregressively generating meshes. This a…
Differentiable Voxelization and Mesh Morphing
Yihao Luo, Yikai Wang, Zhengrui Xiang +3
In this paper, we propose the differentiable voxelization of 3D meshes via the winding number and solid angles. The proposed approach achieves fast, flexible, and accurate voxeliza…
