id | Name | DataType | PartType | Default | ValueType | Description |
---|---|---|---|---|---|---|
alpha | SFBool | inputOutput | TRUE | If FALSE, the alpha color component is removed. | ||
background | MFString | inputOutput | Names of background objects that should be used on this viewarea. If no name is given, the currently bound background is used. If more than one name is given, the first valid backgound is used | |||
blue | SFBool | inputOutput | TRUE | If FALSE, the blue color component is removed. | ||
description | SFString | inputOutput | Textual description of this viewarea | |||
displayFilter | MFNode | inputOutput | DisplayFilter | Holds all optional display filter nodes | ||
enabled | SFBool | inputOutput | TRUE | If FALSE, rendering is disabled | ||
environment | MFString | inputOutput | Names of environment objects that should be used on this viewarea. If no name is given, the currently bound background is used. If more than one name is given, the first valid environment is used | |||
fog | MFString | inputOutput | Names of fog bindable objects that should be used on this viewarea. If no name is given, the currently bound fog is used. If more than one name is given, the first valid fog is used | |||
foreground | MFString | inputOutput | Names of foreground objects that should be used on this viewarea. If no name is given, the currently bound foreground is used. If more than one name is given, the first valid foreground is used | |||
grabFile | SFString | inputOutput | frame%04d.png | Filename that should be used to save grabed images. A sequence number can be used with the sprintf %d operator. | ||
grabFrames | SFInt32 | inputOutput | 0 | If value positive, 'value' rendered images are grabed and written into a file given by grabFile, if value=-1, grabbing is always done, if 0, it is disabled. | ||
green | SFBool | inputOutput | TRUE | If FALSE, the green color component is removed. | ||
inMessageCount | SFInt32 | outputOnly | number of inMessages processed | |||
keyPress | SFInt32 | inputOutput | 0 | Key press event output | ||
keyRelease | SFInt32 | inputOutput | 0 | Key release event output | ||
leftBuffer | SFBool | inputOutput | TRUE | If TRUE, rendering is done to the view buffer for the left eye | ||
logFeature | MFString | inputOutput | state, child, parent, route, eventIn, eventOut | controls the logging of changes, state: log state changes (e.g. live), child: log child add/remove, parent: log parent add/remove, route: log route add/remove; eventIn: log receiving of events, eventOut: log sending of events: guiView, runtime system should create node-view, guiEdit: runtime system should create node-editeverything: log everything | ||
lowerLeft | SFVec2f | inputOutput | 0 0 | Lower left corner of the viewarea. Values less or equal then 1 are treated as relative values. If values are greater then 1, the values are treated as number of pixels | ||
maxIds | SFInt32 | inputOutput | -1 | maximum number of visible objects ids that are send over network | ||
message | SFString | outputOnly | Message to be processed. Valid messages are: toggleFullScreen toggleHeadlight toggleGlobalShadow nextShadowMode toggleLazyInteractionEvalution toggleDrawVolume toggleCullFrustum toggleCullOcclusion nextDrawMode pointDrawMode lineDrawMode fillDrawMode nextInfoScreen firstView lastView nextView prevView resetViewPosition showAll walkNav flyNav freeFlyNav examineNav lookatNav noneNav forward backward left right exportBackendASC exportBackendBIN exit | |||
metadata | SFNode | inputOutput | MetadataObject | container for payload metadata inside MetadataSet element | ||
modifier | MFNode | initializeOnly | ViewModifier | Modifiers are used to add additional features to the viewing matrix. This is used for tiled displays or other complex projections. | ||
mouseMove | SFVec2f | inputOutput | 0 0 | Mouse move event. Gives the position of the mouse in 2D window space | ||
mouseOver | SFBool | inputOnly | FALSE | Emits true, if mouse points to a pointing sensor | ||
mousePress | SFInt32 | inputOutput | 0 | Mouse button press event output | ||
mouseRelease | SFInt32 | inputOutput | 0 | Mouse button release event output | ||
navigator | SFNode | inputOutput | Navigator | Navigator object used for user interaction | ||
objectIds | MFString | inputOutput | Object IDs (DEFed names) of visible objects, sorted by visibility. Does respect maxIds and visibilityThreshold, i.e. objects that are sorted out by these mechanisms will not appear here. | |||
objectVisibilities | MFDouble | inputOutput | [0, 1] | Relative visibility (in [0,1]) of i-th object in objectIds. | ||
outMessageCount | SFInt32 | outputOnly | number of outMessages processed | |||
rayTracingEnabled | SFBool | initializeOnly | TRUE | enable ray tracing. If false, the default (rasterization) renderer is used. | ||
red | SFBool | inputOutput | TRUE | If FALSE, the red color component is removed. | ||
rightBuffer | SFBool | inputOutput | TRUE | If TRUE, rendering is done to the view buffer for the right eye | ||
statisticLevel | SFInt32 | inputOutput | 0 | Statistics level | ||
targetTextures | MFNode | inputOutput | SingleTexture | The textures to render to. Hint: Use a SolidTexture. First entry is the output buffer (the displayed image), specialized nodes may expose additional buffers. | ||
toneMappingParameters | MFFloat | initializeOnly | 0 | tone mapping parameters. | ||
toneMappingType | SFString | initializeOnly | NONE | tone mapping algorithm to be used. Can be NONE, SIGMOID, REINHARD_NONLINEAR. | ||

upperRight | SFVec2f | inputOutput | 1 1 | Upper right corner of the viewarea. Values less or equal then 1 are treated as relative values. If values are greater then 1, the values are treated as number of pixels | ||
useClientCamera | SFBool | inputOutput | true | if true, camera of connected client is used | ||
user | MFString | inputOutput | Names of user bindable objects that should be used on this viewarea. If no name is given, the currently bound user is used. If more than one name is given, the first valid user is used | |||
view | MFString | inputOutput | Names of viewpoint objects that should be used on this viewarea. If no name is given, the currently bound viewpoint is used. If more than one name is given, the first valid viewpoint is used. | |||
visibilityThreshold | SFFloat | inputOutput | 0 | [0, 1] | Objects are considered to be visible if they cover a fraction of the screen greater than this value |
