Point Light
The point light is an omnidirectional light source that emits the same amount of light in all directions, producing hard shadows. The point light represents an infinitely small point in space and can be used as the simplest light model, for example, to simulate a light bulb or a star that illuminates the scene uniformly.
The intensity of the point light can be measured in Watts or Lumens. For details of the intensity controls, see the Common Physical Light Properties section.
Tip
Point lights are not possible in physics, due to their infinitesimally small size. Being a physically based renderer, AMD Radeon ProRender creates a very small sphere light with its center at the point light location. If you wish to add softness for your point light, consider a Sphere light.
