Declaration

#include <Goptical/Trace/Distribution>

namespace Goptical {
  namespace Trace {
    class Distribution;
  };
};

This class is a member of the Trace namespace.

This class describes distribution pattern and ray density used for light ray distribution over surfaces during light propagation.

Ray density is expressed as average number of rays along surface radius.

void set_radial_density(unsigned int count)
void set_scaling(double scaling)
void set_uniform_pattern()

Creates a distribution pattern with specified pattern, radial ray density and scaling.

The scaling ratio parameter may be used to avoid distributing rays too close to the surface edge.

Get distribution pattern

Get current radial density

get current scaling

Set distribution pattern

Set average number of ray to distribute on surface radius

Set scaling, Rays are distributed on surface but are kept away from surface edge if scaling is less than 1.0.

Ensure uniform 2d pattern suitable for spot diagram and image analysis is selected. Change to default pattern if not.
