6.1 Scene» Spot Light A Spot Light is the most common light source to light a scene. It emitslight within a cone that is defined by two angles: a cone angle which defines hardlit areas and a penumbra angle which defines soft lit areas.» Point Light A Point Light emits light from a given position uniformly to all directions.» Properties» Name: Sets the name for the selected light.» Type: Changes the light source type.» Local Lighting: Activating this feature provides light sources to function as a locallight. Only geometry inside the light source node will be lit. This enables the userto set a more sophisticated lighting of the scene.» Enabled: If checked, the light source is active and emits light, if not checked, thelight source is inactive and doesn’t emit any light.» Intensity: Changes the light intensity. Higher values result in brighter lighting.» Ambient: Defines a light’s ambient color. This is the color in dark areas of anobject. This is usually the color where no light is received.» Diffuse: Diffuse color is the color of light of a diffuse reflection (characteristic forlight reflected from a dull, non-shiny surface). A diffuse color attribute specifiesthe color of the light diffusely reflected by the objects to which it is assigned.» Specular: Specular color is the color of the light on shiny surfaces.» Use Temperature: Enables or disables the Temperature value.» Temperature: Changes the color temperature.» Spotlight and Pointlight specific parameters:• Light Attenuation: Sets the falloff of the light intensity. Three values areavailable:· None: Light intensity of light is constant in relation to the distance of light.87
