PI-VR - VRED Professional 4.2 - PI-VR GmbH

Shadow:
Intensity: Changes the intensity of casted Shadows.
Shadow Quality:
Sets the shadow quality for interactive visual feedback and for final render
quality.
This parameter works only in raytracing mode.
Important: Setting this parameter to high values, increases calculation
time.
Shadow Map Resolution:
Sets the quality for OpenGL shadow maps. Higher values increase the quality.
Position/Direction:
Use Camera: Sets the Light position and direction to the current camera
position snd direction.
Create: Creates a new light source. Three different types are available:
- Directional Light
- Spot Light
- Point Light
Delete: deletes the selected light source
Rename: The user have the possibility to rename light sources.
Change Type: Converts existing light sources to different light source types.
Light specific parameters:
Spotlight:
Cone Angle: It is the angle, in degrees, from one edge of the light's beam to the
opposite edge.
Penumbra Angle: The Penumbra Angle controls the falloff, in degrees, of the
edges of the beam. This can be a positive or negative value.
If it's positive, the falloff will occur from the edge of the light determined by the
cone angle, outward by the penumbra angle. Therefore, if the Cone Angle is set
to 30° and the Penumbra Angle is set to 5°, the light has a total angle of 40° (30
+ 5 + 5 - that is 5 degrees on each side). The beams falloff would begin at 30
degrees and would fall off to an intensity of 0 at 40 degrees.
Light Attenuation: Sets the Falloff of the light intensity.
Three values are available:
- Off (Light intensity of light is constant in relation to the distance
of light)
- Linear (Light intensity decreases linear in relation to the
distance of light)
- Quadratic (Light intensity decreases quadratic in relation to the
distance of light)
Area Light:
Use realistic Falloff: Sets the Falloff behavior of an area light to quadratic.
Size: Sets the area light size in mm. The Bigger the light, the brighter. Sets the
shape to a rectangular area light.
Pointlight:
Light Attenuation: Sets the Falloff of the light intensity.
Three values are available:
