GraphicsContext3D

public class GraphicsContext3D extends Object (Code)

A GraphicsContext3D object is used for immediate mode rendering into a 3D canvas. It is created by, and associated with, a specific Canvas3D object. A GraphicsContext3D defines methods to set 3D graphics state and draw 3D geometric primitives. There are no public constructors of GraphicsContext3D. An application obtains a 3D graphics context object from the Canvas3D object that the application wishes to render into by using the getGraphicsContext3D method. A new graphics context is created if one does not already exist. A new GraphicsContext3D initializes its state variables to the following defaults:

Background object: null
Fog object: null
ModelClip object: null
Appearance object: null
List of Light objects: empty
high-res coordinate: (0, 0, 0)
modelTransform: identity
AuralAttributes object: null
List of Sound objects: empty
buffer override: false
front buffer rendering: false
stereo mode: STEREO_BOTH

Note that the drawing methods in this class are not necessarily executed immediately. They may be buffered up for future execution. Applications must call the flush(boolean) method to ensure that the rendering actually happens. The flush method is implicitly called in the following cases:

The readRaster method calls flush(true)
The Canvas3D.swap method calls flush(true)
The Java 3D renderer calls flush(true) prior to swapping the buffer for a double buffered on-screen Canvas3D
The Java 3D renderer calls flush(true) prior to copying into the off-screen buffer of an off-screen Canvas3D
The Java 3D renderer calls flush(false) after calling the preRender, renderField, postRender, and postSwap Canvas3D callback methods.

A single-buffered, pure-immediate mode application must explicitly call flush to ensure that the graphics will be rendered to the Canvas3D.

This means that the application may modify individual appearance attributes by using the appropriate methods on the Appearance object. If the Appearance object is null, default values will be used for all appearance attributes - it is as if an Appearance node were created using the default constructor. Parameters: appearance - the new Appearance object exception: IllegalSharingException - if the specified appearance refersto an ImageComponent2D that is being used by a Canvas3D asan off-screen buffer.

The Background node must not be part of a live scene graph, nor may it subsequently be made part of a live scene graph-an IllegalSharingException is thrown in such cases. If the Background object is null, the default background color of black (0,0,0) is used to clear the canvas prior to rendering a new frame. The Background node's application region is ignored for immediate-mode rendering. Parameters: background - the new Background object exception: IllegalSharingException - if the Background nodeis part of or is subsequently made part of a live scene graph. exception: IllegalSharingException - if the specified background noderefers to an ImageComponent2D that is being used by a Canvas3D asan off-screen buffer.

setBufferOverride
public void setBufferOverride(boolean bufferOverride)(Code)
	Sets a flag that specifies whether the double buffering and stereo mode from the Canvas3D are overridden. When set to true, this attribute enables the `frontBufferRendering` and `stereoMode` attributes. Parameters: bufferOverride - the new buffer override flag See Also: GraphicsContext3D.setFrontBufferRendering See Also: GraphicsContext3D.setStereoMode since: Java 3D 1.2

setFog
public void setFog(Fog fog)(Code)
	Sets the current Fog to the specified Fog leaf node object. The graphics context stores a reference to the specified Fog node. This means that the application may modify the fog attributes using the appropriate methods on the Fog node object. The Fog node must not be part of a live scene graph, nor may it subsequently be made part of a live scene graph-an IllegalSharingException is thrown in such cases. If the Fog object is null, fog is disabled. Both the region of influence and the hierarchical scope of the Fog node are ignored for immediate-mode rendering. Parameters: fog - the new Fog object exception: IllegalSharingException - if the Fog nodeis part of or is subsequently made part of a live scene graph.

setFrontBufferRendering
public void setFrontBufferRendering(boolean frontBufferRendering)(Code)
	Sets a flag that enables or disables immediate mode rendering into the front buffer of a double buffered Canvas3D. This attribute is only used when the `bufferOverride` flag is enabled. Note that this attribute has no effect if double buffering is disabled or is not available on the Canvas3D. Parameters: frontBufferRendering - the new front buffer rendering flag See Also: GraphicsContext3D.setBufferOverride since: Java 3D 1.2

setHiRes
public void setHiRes(int[] x, int[] y, int[] z)(Code)
	Sets the HiRes coordinate of this context to the location specified by the parameters provided. The parameters x, y, and z are arrays of eight 32-bit integers that specify the high-resolution coordinates point. Parameters: x - an eight element array specifying the x position Parameters: y - an eight element array specifying the y position Parameters: z - an eight element array specifying the z position See Also: HiResCoord

setHiRes
public void setHiRes(HiResCoord hiRes)(Code)
	Sets the HiRes coordinate of this context to the location specified by the HiRes argument. Parameters: hiRes - the HiRes coordinate specifying the a new location

setLight
public void setLight(Light light, int index)(Code)
	Replaces the specified light with the light provided. The graphics context stores a reference to each light object in the list of lights. This means that the application may modify the light attributes for any of the lights using the appropriate methods on that Light node object. None of the Light nodes in the list of lights may be part of a live scene graph, nor may they subsequently be made part of a live scene graph - an IllegalSharingException is thrown in such cases. Parameters: light - the new light Parameters: index - which light to replace exception: IllegalSharingException - if the Light nodeis part of or is subsequently made part of a live scene graph. exception: NullPointerException - if the Light object is null.

setModelClip
public void setModelClip(ModelClip modelClip)(Code)
	Sets the current ModelClip leaf node to the specified object. The graphics context stores a reference to the specified ModelClip node. This means that the application may modify the model clipping attributes using the appropriate methods on the ModelClip node object. The ModelClip node must not be part of a live scene graph, nor may it subsequently be made part of a live scene graph-an IllegalSharingException is thrown in such cases. If the ModelClip object is null, model clipping is disabled. Both the region of influence and the hierarchical scope of the ModelClip node are ignored for immediate-mode rendering. Parameters: modelClip - the new ModelClip node exception: IllegalSharingException - if the ModelClip nodeis part of or is subsequently made part of a live scene graph. since: Java 3D 1.2

setModelTransform
public void setModelTransform(Transform3D t)(Code)
	Sets the current model transform to a copy of the specified transform. A BadTransformException is thrown if an attempt is made to specify an illegal Transform3D. Parameters: t - the new model transform exception: BadTransformException - if the transform is not affine.

setSound
public void setSound(Sound sound, int index)(Code)
	Replaces the specified sound with the sound provided. The graphics context stores a reference to each sound object in the list of sounds. This means that the application may modify the sound attributes for any of the sounds by using the appropriate methods on that Sound node object. Parameters: sound - the new sound Parameters: index - which sound to replace exception: IllegalSharingException - if the Sound nodeis part of or is subsequently made part of a live scene graph. exception: NullPointerException - if the Sound object is null.

setStereoMode

public void setStereoMode(int stereoMode)(Code)

Sets the stereo mode for immediate mode rendering. The parameter specifies which stereo buffer or buffers is rendered into. This attribute is only used when the bufferOverride flag is enabled.

STEREO_LEFT specifies that rendering is done into the left eye.
STEREO_RIGHT specifies that rendering is done into the right eye.
STEREO_BOTH specifies that rendering is done into both eyes. This is the default.

Note that this attribute has no effect if stereo is disabled or is not available on the Canvas3D.
Parameters:
  stereoMode - the new stereo mode
See Also:   GraphicsContext3D.setBufferOverride

   Java 3D 1.2
