  • 3D model rendering method and apparatus and terminal device
    Patent number: 9916676
    Abstract: The present application discloses a 3D model rendering method and apparatus and a terminal device. The method includes calculating, in a diffuse reflection illumination situation simulated by hardware, dot product operation results of a light vector and a normal line vector of each vertex on a surface of a 3D model, converting the dot product operation results of each vertex to corresponding UV coordinate values, then drawing, according to a preset correspondence between UV coordinate values and a color value of a 3D model basic texture after receiving light, a gradient map having a color value corresponding to the UV coordinate values of the each vertex, and covering the surface of the 3D model with the gradient map.
