GLMode is the value used in glEnable/glDisable(mode).
|
|
GLModeValue is used to specified whether an mode is enabled (ON) or disabled (OFF). GLMoveValue is also used to specify the override behavior of modes from parent to children. See enum Value description for more details. |
|
Override is used to specified the override behavior of StateAttributes from from parent to children. See enum Value description for more details. |
|
Type identifier to differentiate between different state types.
|
|
Values of StateAttribute::Type used to aid identification of different StateAttribute subclasses. Each subclass defines it own value in the virtual Type getType() method. When extending the osg's StateAttribute's simply define your own Type value which is unique, using the StateAttribute::Type enum as a guide of what values to use. If your new subclass needs to override a standard StateAttriubte then simple use that types value.
|
|
list values which can be used in to set either GLModeValues or OverrideValues. When using in conjunction with GLModeValues all Values have meaning. When using in conjection with StateAttribute OverrideValue only OFF,OVERRIDE and INHERIT are meaningful. However, they are useful when using GLModeValue and OverrideValue in conjunction with each other as when using StateSet::setAttributeAndModes(..).
