Module Osg.State_attribute


module State_attribute: sig .. end
Base class for state attributes.
type t
osg::StateAttribute holder

type values =
| OFF
| ON
| OVERRIDE
| PROTECTED
| INHERIT
Values which can be used 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 Osg.State_set.set_attribute_and_modes.

Enumerator: * OFF means that associated GLMode and Override is disabled. * ON means that associated GLMode is enabled and Override is disabled. * OVERRIDE Overriding of GLMode's or StateAttributes is enabled, so that state below it is overridden. * PROTECTED Protecting of GLMode's or StateAttributes is enabled, so that state from above cannot override this and below state. * INHERIT means that GLMode or StateAttribute should be inherited from above.
