Nvidia的GPU Gems3 引入并改进了texture-space diffusion,这个算法通过将3Dmesh展开为2D的纹理,然后在2D的纹理上进行blur(滤波),由于滤波的过程是加权平均,所以只要滤波核是根据剖面函数得来的,那么结果就等价于周围像素根据剖面函数进行次表面散射后对当前像素的贡献。 如果滤波前的纹理记录了物体表面接收到的光,那么经...
如图2ª2D diffusionº所示,扩散模型产生了不一致的纹理,并存在不连续的问题。 方法 第3.2节中提到的挑战促使我们提出一个从粗到细的纹理图像合成框架,即点-紫外扩散,如图4所示。首先,我们设计了一个三维点扩散模型来为网格表面上的一组采样点着色,如图4(顶部)所示。这个阶段利用3D拓扑来预测网格上的低频颜色,...
Much work has been done in the field of texture analysis and classification. While promising classification methods have been proposed, most of them rely on classical image analysis approaches. This paper presents a texture classification method based on diffusion in directed networks. First, an ...

Paint3D: Paint Anything 3D with Lighting-Less Texture Diffusion Models https://github.com/OpenTexture/Paint3D 近年来随着深度生成模型的发展,在自然语言生成、图像合成以及3D对象生成等领域都取得了很大进步。但是,大多数3D生成技术产生的3D物体表面都带有复杂的照明纹理,这与传统渲染管线如物理基础渲染不兼容。所...
Spatial confinement in nanoporous media affects the structure, thermodynamics and mobility of molecular soft matter often markedly. This article reviews thermodynamic equilibrium phenomena, such as physisorption, capillary condensation, crystallisation, self-diffusion, and structural phase transitions as well as...
总结:在线版的Stable Diffusion XL,生成比较好的贴图需要很多提示词,相较于材质贴图,这个网站体验并不算很好,好在功能比较多,大部分功能免费使用,可以配合其他AI网站使用。 「texturelab」 https://www.texturelab.xyz/# 材质纹理生成网站,通过英文提示词生成材质纹理,优点是生成速度快,积分给的比较多,缺点是只能生成...
手工质感的漫画风格 | 最开始的想法是,能不能把贞本义行的风格用stablediffusion弄出来? 众所周知,模型若要追求一种风格,最好的方法是直接上素材集训练,但本人懒狗一条,向来图方便直接融合画风相似的模型,最终,花了很多时间,没有理想结果,退而求其次靠一大堆提示词得到了一个自己还比较喜欢的风格。
An alternative explanation concerns temperature effects on dislocation slip. Texture development slows down at higher temperatures as less dislocation slip is needed because ofdiffusion processes. The higherthermal energyalso enables dislocations to participate in plastic relaxation, which promotes the developme...
