What is MVPaint
MVPaint is a 3D texture generation framework jointly launched by Tencent PCG, Shanghai AI LAB, Nanyang Technological University S-Lab, and Tsinghua University. It is based on synchronized multi-view diffusion technology to achieve high-resolution, seamless, and multi-view consistent 3D texture generation. MVPaint includes three core modules: Synchronized Multi-view Generation (SMG) used for initializing textures, Spatially-aware 3D Inpainting (S3I) used for filling unobserved regions, and UV Refinement (UVR) used for improving texture quality in UV space. MVPaint significantly improves the texture generation effect of 3D models and reduces local discontinuities and multi-view inconsistency issues.
Main Features of MVPaint
- Synchronized Multi-view Generation:Simultaneously generates images from multiple viewpoints, providing preliminary textures for the 3D model.
- Spatially-aware 3D Inpainting: Specially designed texturing for regions not observed in multi-view generation, ensuring complete texture coverage of the 3D model.
- UV Refinement (UVR): Includes super-resolution processing in UV space and a spatially-aware seam smoothing algorithm, improving texture quality after UV unwrapping and correcting discontinuities caused by UV unwrapping.
- Multi-view Consistency: MVPaint emphasizes maintaining consistency in textures generated from different viewpoints, reducing inconsistency issues caused by viewpoint changes.
- High-resolution Texture Generation: Generates high-resolution and seamless textures, improving the visual quality of 3D models.
Technical Principles of MVPaint
- Control-based T2MV Model: Uses a control-based model to generate multi-view images from text descriptions, which is part of Synchronized Multi-view Generation (SMG).
- Image-to-Image Model (I2I): Together with the control-based multi-view model, the I2I model is used for initializing 3D textures.
- 3D Point Cloud Inpainting: In UV space, based on 3D point cloud inpainting technology, it fills unobserved regions and is the core of Spatially-aware 3D Inpainting (S3I).
- UV Space Super-resolution: In the UVR module, super-resolution processing is performed on the UV map to increase texture details.
- Spatially-aware Seam Smoothing: In UV space, MVPaint detects seams and applies a 3D-aware smoothing algorithm to correct texture discontinuities caused by UV unwrapping.
- Multi-view Consistency Preservation: Throughout the texture generation process, MVPaint ensures texture consistency across different viewpoints based on synchronized multi-view generation and subsequent processing steps.
