fz_shdr_get_diffuse_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 diffuse 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_diffuse_parm().

Plugin Prototype

void fz_shdr_get_diffuse_factor(

double *

fval )

Parameters

fval [Result]

The current value of the diffuse reflection parameter.

Returns

none

Availability

5.0.0.0

Plugin Example

Typically, the diffuse factor is multiplied with the result of the diffuse illumination term to yield the final diffuse shading color. :
fz_shdr_get_diffuse_factor(&diff_factor); fz_shdr_get_diffuse_term(&diff_col); diff_col *= diff_factor;
