【発明の名称】テクスチャマッピング方法およびその装置
Document Type and Number:
Japanese Patent JP3107452
Kind Code:
B2
Abstract:
Intensities of light reflected from a surface of an object to be displayed are calculated as to values of an ambient light reflection component, a diffuse light reflection component, and a specular reflection component. Judgement is made as whether the calculated value of the specular reflection component exceed a predetermined value. Texture data are blended with a sum of the calculated ambient light reflection component value and the calculated diffuse light reflection component value. If it is judged that the calculated specular reflection component value exceeds the predetermined value, the specular reflection component value is added to the blended value of the texture data with the sum of the calculated ambient light reflection component value and the calculated diffuse light reflection component value.
