Public Member Functions | |
| Diffuse (const Color &c, float r=0.0f, float t=0.0f, float n=1.0f) | |
| Constructs a diffuse (Lambertian) material with color c, and (optionally) reflectivity r and transparency t, and index of refraction n. | |
| virtual | ~Diffuse () |
| Destructor. | |
| Color | getBRDF (const Intersection &is, const Vector &L) |
| Returns the BRDF at the intersection is for the light direction L. | |
| virtual float | getReflectivity (const Intersection &is) const |
| Returns the reflectivity of the material in the range [0,1] at the intersection, where 0 means not reflective at all, and 1 gives a perfect mirror. | |
| virtual void | setReflectivity (float r) |
| Sets the reflectivity of the material. | |
| virtual float | getTransparency (const Intersection &is) const |
| Returns the transparency of the material in the range [0,1] at the intersection, where 0 is fully opaque, and 1 is fully transparent. | |
| virtual void | setTransparency (float t) |
| Sets the transparency of the material. | |
| virtual float | getIndexOfRefraction () const |
| Returns the index of refraction for the material. | |
| virtual void | setIndexOfRefraction (float n) |
| Sets the index of refraction. Empty space is 1, denser materials higher. | |
Protected Attributes | |
| Color | mDiffColor |
| The diffuse color. | |
| float | mReflectivity |
| The reflectivity of the material. | |
| float | mTransparency |
| The transparency of the material. | |
| float | mRefractionIndex |
| Index of refraction for the material. | |
Only the normal and light vector are used in the evaluation of the BRDF, hence the viewing direction does not matter.
