# fz_shdr_get_specular_factor

Description

This function can only be called inside the pixel callback function when implementing a plugin or script reflection shader. It retrieves the current value of the specular reflection parameter. This parameter must have been declared in the set_parameters callback function of the same shader via a call to fz_shdr_set_specular_parm().

Plugin Prototype

void fz_shdr_get_specular_factor(

double * | fval )

Parameters

fval [Result]

The current value of the specular reflection parameter.

Returns

none

Availability

5.0.0.0

Plugin Example

Typically, the specular factor is multiplied with the result of the specular illumination term to yield the final specular shading color. :
fz_shdr_get_specular_factor(&spec_factor); fz_shdr_get_specular_term(1.0 / roughness,&spec_col); spec_col *= spec_factor;
