The LightEditor provides all functionalities for creating
an manipulating all available light sources. Per default
the headlight is the only light source. It will be
automatically disabled if new light sources are
created. Three different light types are available :
Directional Light
A directional light has no origin. It is an
infinite light with one direction. It is
often used to simulate outdoor lighting
like sunlight,
Spotlight
A spotlight is the most common light source to light a scene. It is a directional
light with an origin and has a cone angle which defines the hard lit areas and a
penumbra angle which defines the soft lit areas.
Point Light
A Point light is a non direction light with a point as an origin. Light is emitted to
all directions.
Common parameters
Object
Name - Sets the name for the selected light
Type - Changes the light source type
Enabled - Enables light source or disables it.
Local lighting - Activating this feature provides light sources to function as a
local light. Only geometry inside the light source node will be lit. This enables
the user to set a more sophisticated lighting of the scene.
Visualization
Show all lights - Unhides all available light source geometries in the scene for
visual feedback and interactive transformation actions like scale, rotate and
translate.
Hide all lights - Hides all available light source geometries in the scene.
Color
Scale - Scales the light source geometry in the Scene for better visual
feedback.
Ambient - Defines the ambient color of a light. This is the color in the dark
areas of an object. This is usually the color where no light is received.
Diffuse - Diffuse color is the color of the light of a diffuse reflection (the type of
reflection that is characteristic of light reflected from a dull, non-shiny surface).
A diffuse color attribute specifies the 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.
Intensity - Changes the light intensity. Higher values result in brighter lighting.
Shadow
Intensity - Changes the intensity of casted Shadows.
