formZ SDK | 5.0 API Reference | Project | Modeling | Rendering | Shaders
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 ambient 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_ambient_parm().
Plugin Prototype
void fz_shdr_get_ambient_factor(
double * | fval ) |
Parameters
fval [Result]
The current value of the ambient reflection parameter.
Returns
none
Availability
5.0.0.0
Plugin Example
Typically, the ambient factor is multiplied with the
result of the ambient illumination term to yield the final
ambient shading color. :
fz_shdr_get_ambient_factor(&ambt_factor);
fz_shdr_get_ambient_term(&ambt_col);
ambt_col *= ambt_factor;
