CityPaint 使用 2D 扩散模型进行城市级 3D 纹理处理

研究人员开发了 CityPaint,一个旨在为虚拟现实和城市数字孪生等应用生成高保真、城市级 3D 纹理的新框架。与以往在 3D 训练数据稀缺方面遇到困难的方法不同,CityPaint 利用了丰富的 2D 图像数据和 2D 扩散模型。该系统集成了几何先验和生成能力,采用新颖的相机烘焙策略进行迭代纹理投影,并通过解耦的精炼机制分别优化地形和建筑纹理。实验表明,CityPaint 能够生成具有精细局部细节的全局一致纹理,在视觉质量和一致性方面优于现有基线。 AI

影响 这项研究可以提高游戏和虚拟现实应用中 3D 环境创建的真实感和效率。
