Sys::SourcePoint class reference
[Core module]

This class is a member of the Sys namespace.

This class implement a point light source. The source can either be infinitely far away with a direction vector, or located at a given position but without direction.

A ray is generated for each defined spectrum line for each distribution pattern point on target surface.

Default wavelen list contains a single 550nm entry.

• void set_mode(SourceInfinityMode mode)
• void set_position(const Math::Vector3 &pos)

Create a point source with given mode. A direction vector must be provided when source is in infinity mode. If not in infinity mode, a position vector must be provided instead.

Set point source mode to infinity and adjust source direction vector

Change current point source infinity mode

This function shadows the set_position function defined in the Element base class.

Set point source mode to positioned and adjust source position vector
