标题： ProcTex: Consistent and Interactive Text-to-texture Synthesis for Procedural Models

摘要： 最近在二维图像扩散模型方面的进展推动了文本引导的纹理合成的重大进步，使得可以从任意文本提示中生成逼真、高质量的纹理。 然而，当前方法通常专注于合成单个静态三维物体的纹理，并难以处理整个形状家族，例如由程序化程序生成的形状。 将现有方法直接应用于每个程序化形状会过于缓慢，无法支持以交互速率探索不同的参数设置，同时也会导致程序化形状之间的纹理不一致。 为此，我们引入了ProcTex，这是首个为程序化三维模型设计的文本到纹理系统。 ProcTex实现了形状家族的一致且实时的文本引导纹理合成，能够无缝集成到程序化模型的交互设计流程中。 为了确保一致性，我们的核心方法是为程序化参数的一种设置生成纹理，然后通过一个纹理迁移阶段将纹理应用到其他参数设置上。 我们还开发了几种技术，包括用于实时纹理迁移的新颖UV位移网络，用于支持从离散程序化参数中进行结构变化的重新纹理管道，以及用于局部外观编辑的部分级UV纹理图生成。 在一系列多样化的职业程序化模型上的大量实验验证了ProcTex在生成高质量、视觉一致的纹理的同时支持实时交互应用的能力。 显示英文摘要

摘要： Recent advancement in 2D image diffusion models has driven significant progress in text-guided texture synthesis, enabling realistic, high-quality texture generation from arbitrary text prompts. However, current methods usually focus on synthesizing texture for single static 3D objects, and struggle to handle entire families of shapes, such as those produced by procedural programs. Applying existing methods naively to each procedural shape is too slow to support exploring different parameter settings at interactive rates, and also results in inconsistent textures across the procedural shapes. To this end, we introduce ProcTex, the first text-to-texture system designed for procedural 3D models. ProcTex enables consistent and real-time text-guided texture synthesis for families of shapes, which integrates seamlessly with the interactive design flow of procedural models. To ensure consistency, our core approach is to generate texture for the shape produced by one setting of the procedural parameters, followed by a texture transfer stage to apply the texture to other parameter settings. We also develop several techniques, including a novel UV displacement network for real-time texture transfer, the retexturing pipeline to support structural changes from discrete procedural parameters, and part-level UV texture map generation for local appearance editing. Extensive experiments on a diverse set of professional procedural models validate ProcTex's ability to produce high-quality, visually consistent textures while supporting real-time, interactive applications.
