osg.StateAttribute¶

class osg.StateAttribute¶

Represents: c++ class
Wraps: osg::StateAttribute
Bases: osg.Object

Base class for state attributes.

Methods:

:asTexture()¶

Fast alternative to dynamic_cast<> for determining if osg.StateAttribute is a osg.Texture.

Тип результата: osg.Texture

:getType()¶

Return the osg.StateAttribute.Type identifier of the attribute’s class type.

Тип результата: osg.StateAttribute.Type

:getMember()¶

Return the member identifier within the attribute’s class type. Used for light number/clip plane number etc.

Тип результата: unsigned

:getTypeMemberPair()¶: Return the TypeMemberPair that uniquely identifies this type member. In Lua returns two values: osg.StateAttribute.Type and corresponding value (unsiged number).

:isTextureAttribute()¶

Return true if osg.StateAttribute is a type which controls texturing and needs to be issued w.r.t to specific texture unit.

Тип результата: bool

:getParent(unsigned index)¶

Get a single parent of this StateAttribute.

Параметры: index (unsigned) – index of the parent to get.
Тип результата: osg.StateSet

:getNumParents()¶

Get the number of parents of this StateAttribute.

Тип результата: unsigned

:setShaderComponent(osg.ShaderComponent sc)¶

Параметры: sc (osg.ShaderComponent) –

:getShaderComponent()¶

Тип результата: osg.ShaderComponent

:setUpdateCallback(osg.StateAttributeCallback cb)¶

Set the UpdateCallback of type osg.StateAttributeCallback which allows users to attach customize the updating of an object during the update traversal.

Параметры: cb (osg.StateAttributeCallback) –

:getUpdateCallback()¶

Get the UpdateCallback of type osg.StateAttributeCallback.

Тип результата: osg.StateAttributeCallback

:setEventCallback(osg.StateAttributeCallback cb)¶

Set the EventCallback of type osg.StateAttributeCallback which allows users to attach customize the updating of an object during the Event traversal.

Параметры: cb (osg.StateAttributeCallback) –

:getEventCallback()¶

Get the EventCallback of type osg.StateAttributeCallback.

Тип результата: osg.StateAttributeCallback

:apply(osg.State state)¶

Apply the OpenGL state attributes. The render info for the current OpenGL context is passed in to allow the osg.StateAttribute to obtain details on the the current context and state.

Параметры: state (osg.State) –

:compileGLObjects(osg.State state)¶

Default to nothing to compile - all state is applied immediately.

Параметры: state (osg.State) –

:resizeGLObjectBuffers(unsigned maxSize)¶

Resize any per context GLObject buffers to specified size.

Параметры: maxSize (unsigned) –

:releaseGLObjects(osg.State state)¶

Release OpenGL objects in specified graphics context if osg.State object is passed, otherwise release OpenGL objects for all graphics context if osg.State object is nil.

Параметры: state (osg.State) –

:releaseGLObjects()
