Method Details

onStartRender

SbEventHandler<SiRenderArea.RenderEventArg> onStartRender()

Returns the event handler that raises when a new render starts.

setClearPolicy

void setClearPolicy(SiRenderArea.ClearPolicies policy)

Defines the color buffer and depth buffer clear policy. See also setClearColor and setClearDepth.

Parameters:

policy - color buffer and depth buffer clear policy.

getSize

SbVec2i32 getSize()

See Also:

• setSize()

render

SiRenderArea.RenderStatus render()

Render the managed scene graph (see setSceneGraph). See RenderStatus documentation for details on the returned value.

setSceneGraph

void setSceneGraph(SoNode newScene)

Defines the scene graph which is managed here. This is the Open Inventor scene which will be traversed for rendering and event processing.

Parameters:

newScene - scene graph.

getSceneGraph

SoNode getSceneGraph()

See Also:

• setSceneGraph()

getClearDepth

float getClearDepth()

See Also:

• setClearDepth()

getClearColor

SbColorRGBA getClearColor()

See Also:

• setClearColor()

setClearDepth

void setClearDepth(float depth)

Defines the depth value used when the depth buffer is cleared. See also setClearPolicy.

Parameters:

depth - value used to clear the depth buffer.

getClearPolicy

SiRenderArea.ClearPolicies getClearPolicy()

See Also:

• setClearPolicy()

setSize

void setSize(SbVec2i32 size)

Defines the size to use for rendering.

setClearColor

void setClearColor(SbColorRGBA color)

Defines the RGBA value used when the color buffer is cleared. See also setClearPolicy.

Parameters:

color - RGBA value used to clear the color buffer.
