This may either be procedural textures ( some metal ) , i . e . textures that are created by a mathematical formula , images , or environment maps to create the impression of reflections and refractions 這可能是程序紋理(某些金屬)即通過數(shù)學(xué)公式創(chuàng)建的紋理,圖片或者環(huán)境映射來制造對反射和折射的效果。
Antialiasing in two - dimensional texture mappings is also discussed including a modified summed - area table algorithm . three - dimensional texture mappings are summarized including several procedural texture functions and fourier synthesis techniques 在三維紋理方面,重點分析了幾種常用的過程紋理函數(shù)與fourier紋理合成技術(shù),并對傳統(tǒng)的木紋函數(shù)進(jìn)行了改進(jìn)。
