java.lang.Object com.imsl.chart.AbstractChartNode com.imsl.chart3d.ChartNode3D com.imsl.chart3d.PointLight
A point light source.
A point light source is at a fixed point in space and radiates light equally in all directions away from the light source. The light's position is defined by the attribute "Position".
The light's position is in a coordinate system in which the default viewport is the cube [-1,1] by [-1,1] by [-1,1].
