Specular and Diffuse Reflection - Definition, Differences

WebWhen enabled, textures will stream in based on what is visible on screen. The texture streamer increases and decreases the resolution of visible textures, allowing for visual quality where it matters while managing available memory more efficiently. Use DXT5 Normal Maps. Defines whether to use DXT5 for normal maps. WebSimple Illumination Model Surfaces in real world environments receive light in 3 ways: 1. sources such as the sun or a lit candle 2. through transparent objects such as water or a glass vase 3. diffused from other … WebAs the angle between the view (V) and the reflected light (R) decreases, you will get more specularity. The clever thing about Phong's equation was that it gave a neat way to calculate the specular intensity 'bump' around the light reflection vector (R). The larger the exponential power (n) the smaller and more intense the specular intensity bump. burnout ingles
