Members detail

Base()

Material base constuctor. Set material temperature to 20.

virtual ~Base()

No documentation available

virtual Io::Rgb get_color() const

Get material color and alpha

virtual double get_extinction_coef(double wavelen) const

Get extinction coefficient. Subclasses _must_ provide this function or the get_internal_transmittance() function.

virtual double get_internal_transmittance(double wavelen, double thickness) const

Get material internal transmittance for thickness in mm. Subclasses _must_ provide this function or the get_extinction_coef() function.

double get_internal_transmittance(double wavelen) const

Get material internal transmittance for 1mm thickness.

virtual double get_normal_reflectance(const Base *from, double wavelen) const

Get reflectance at normal incidence

virtual double get_normal_transmittance(const Base *from, double wavelen) const

Get transmittance at normal incidence

virtual double get_refractive_index(double wavelen) const = 0;

Get material absolute refractive index at specified wavelen in nm.

double get_refractive_index(double wavelen, const Base &env) const

Get material relative refractive index in given medium at specified wavelen in nm.

virtual double get_temperature() const

Get material temperature in celcius

virtual bool is_opaque() const = 0;

Return true if material must be considered opaque for ray tracing

virtual bool is_reflecting() const = 0;

Return true if material may reflect most of the light and must be considered as a mirror when ignoring ray intensity computation during ray tracing.

void set_temperature(double temp)

Set material temperature in celcius
