Solid textures, comprising 3D particles embedded in a matrix in a regular or semiregular pattern, are common in natural and man-made materials, such as brickwork, stone walls, plant cells in a leaf, etc. We present a novel technique for synthesizing such textures, starting from 2D image exemplars which provide cross-sections of the desired volume texture. The shapes and colors of typical particles embedded in the structure are estimated from their 2D cross-sections. Particle positions in the texture images are also used to guide spatial placement of the 3D particles during synthesis of the 3D texture. Our experiments demonstrate that our algorithm can produce higher quality structures than previous approaches; they are both compatible with the input images, and have a plausible 3D nature.
固体纹理由嵌入在规则或半规则图案中的基质中的 3D 颗粒组成,在天然和人造材料中很常见,例如砖砌体、石墙、叶片中的植物细胞等。我们提出了一种从 2D 图像范例开始合成这种纹理的新方法,这些范例提供了所需体积纹理的横截面。从其 2D 横截面中估计嵌入结构中的典型颗粒的形状和颜色。纹理图像中的颗粒位置也用于在合成 3D 纹理时指导 3D 颗粒的空间放置。我们的实验表明,我们的算法可以生成比以前的方法质量更高的结构;它们既与输入图像兼容,又具有合理的 3D 性质。
