LightManager

Manage a set of lights that can cast hard and soft shadows.Soft Shadows is done using Variance Shadow Mapping (http://developer.download.nvidia.com/SDK/10.5/direct3d/Source/VarianceShadowMapping/Doc/VarianceShadowMapping.pdf)

Target: Sofa.GL.Component.Shader

namespace: sofa::gl::component::shader

parents:

  • VisualManager

Data

Name Description Default value
name object name unnamed
printLog if true, emits extra messages at runtime. 0
tags list of the subsets the object belongs to
bbox this object bounding box
componentState The state of the component among (Dirty, Valid, Undefined, Loading, Invalid). Undefined
listening if true, handle the events, otherwise ignore the events 0
enable Display the object or not 1
shadows Enable Shadow in the scene. (default=0) 0
softShadows If Shadows enabled, Enable Variance Soft Shadow in the scene. (default=0) 0
ambient Ambient lights contribution (Vec4f)(default=[0.0f,0.0f,0.0f,0.0f]) 0 0 0 1
debugDraw enable/disable drawing of lights shadow textures. (default=false) 0
Name Description Destination type name
context Graph Node containing this object (or BaseContext::getDefault() if no graph is used) BaseContext
slaves Sub-objects used internally by this object BaseObject
master nullptr for regular objects, or master object for which this object is one sub-objects BaseObject
