高光映射Specular light maps

通过光源照亮时,采用高反光材质的闪光对象会接收反射高光。When illuminated by a light source, shiny objects that use highly reflective materials receive specular highlights. 有时,相较于使用照明模块产生的反射高光,你可通过将高光映射应用至基元获取更精确的高光。Sometimes you can get more accurate highlights by applying specular light maps to primitives, rather than using the specular highlights produced by the lighting module.

将高光映射添加至基元纹理,然后进行调制(将结果乘以)RGB 光映射,以进行高光映射。To perform specular light mapping, add the specular light map to the primitive's texture, then modulate (multiply the result by) the RGB light map.
