stackgl/glsl-specular-blinn-phong

This is a GLSL utility for calculating the specular weight component of the Blinn-Phong lighting model, commonly used in 3D graphics rendering. It provides a `blinnPhong` function that takes light direction, eye direction, surface normal, and shininess parameters to compute the specular power for realistic lighting effects. The library is designed for graphics developers working with GLSL shaders, particularly those using npm and glslify for shader module management.
