Description" .PP The \fBSoVRMLCollision\fP class is used for collision detection with the avatar\&. \fBThe detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997)\&. It is copyright The Web3D Consortium, and is used by permission of the Consortium:\fP .br .br .PP .nf Collision { eventIn MFNode addChildren eventIn MFNode removeChildren exposedField MFNode children [] exposedField SFBool collide TRUE field SFVec3f bboxCenter 0 0 0 # (-,) field SFVec3f bboxSize -1 -1 -1 # (0,) or -1,-1,-1 field SFNode proxy NULL eventOut SFTime collideTime } .fi .PP .PP The Collision node is a grouping node that specifies the collision detection properties for its children (and their descendants), specifies surrogate objects that replace its children during collision detection, and sends events signalling that a collision has occurred between the avatar and the Collision node's geometry or surrogate\&. By default, all geometric nodes in the scene are collidable with the viewer except IndexedLineSet, PointSet, and Text\&. Browsers shall detect geometric collisions between the avatar (see \fBSoVRMLNavigationInfo\fP) and the scene's geometry and prevent the avatar from 'entering' the geometry\&. See 4\&.13\&.4, Collision detection and terrain following (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.13.4), for general information on collision detection\&. .PP If there are no Collision nodes specified in a VRML file, browsers shall detect collisions between the avatar and all objects during navigation\&. .PP Subclause 4\&.6\&.5, Grouping and children nodes (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.5), contains a description of the children, addChildren, and removeChildren fields and eventIns\&. .PP The Collision node's collide field enables and disables collision detection\&. If collide is set to FALSE, the children and all descendants of the Collision node shall not be checked for collision, even though they are drawn\&. This includes any descendent Collision nodes that have collide set to TRUE (i\&.e\&., setting collide to FALSE turns collision off for every node below it)\&. .PP Collision nodes with the collide field set to TRUE detect the nearest collision with their descendent geometry (or proxies)\&. When the nearest collision is detected, the collided Collision node sends the time of the collision through its collideTime eventOut\&. If a Collision node contains a child, descendant, or proxy (see below) that is a Collision node, and both Collision nodes detect that a collision has occurred, both send a collideTime event at the same time\&. A collideTime event shall be generated if the avatar is colliding with collidable geometry when the Collision node is read from a VRML file or inserted into the transformation hierarchy\&. .PP The bboxCenter and bboxSize fields specify a bounding box that encloses the Collision node's children\&. This is a hint that may be used for optimization purposes\&. The results are undefined if the specified bounding box is smaller than the actual bounding box of the children at any time\&. A default bboxSize value, (-1, -1, -1), implies that the bounding box is not specified and if needed shall be calculated by the browser\&. More details on the bboxCenter and bboxSize fields can be found in 4\&.6\&.4, Bounding boxes\&. (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.4), .PP The collision proxy, defined in the proxy field, is any legal children node as described in 4\&.6\&.5, Grouping and children nodes, (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.5), that is used as a substitute for the Collision node's children during collision detection\&. The proxy is used strictly for collision detection; it is not drawn\&. If the value of the collide field is TRUE and the proxy field is non-NULL, the proxy field defines the scene on which collision detection is performed\&. If the proxy value is NULL, collision detection is performed against the children of the Collision node\&. If proxy is specified, any descendent children of the Collision node are ignored during collision detection\&. If children is empty, collide is TRUE, and proxy is specified, collision detection is performed against the proxy but nothing is displayed\&. In this manner, invisible collision objects may be supported\&. .PP The collideTime eventOut generates an event specifying the time when the avatar (see \fBSoVRMLNavigationInfo\fP) makes contact with the collidable children or proxy of the Collision node\&. An ideal implementation computes the exact time of collision\&. Implementations may approximate the ideal by sampling the positions of collidable objects and the user\&. The \fBSoVRMLNavigationInfo\fP node contains additional information for parameters that control the avatar size\&. .SH "Constructor & Destructor Documentation" .PP .SS "SoVRMLCollision::SoVRMLCollision (void )" Constructor\&. .SS "SoVRMLCollision::SoVRMLCollision (int numchildren)" Constructor\&. \fInumchildren\fP is the expected number of children\&. .SS "SoVRMLCollision::~SoVRMLCollision ()\fR [protected]\fP, \fR [virtual]\fP" Destructor\&. .SH "Member Function Documentation" .PP .SS "\fBSoType\fP SoVRMLCollision::getClassTypeId (void )\fR [static]\fP" This static method returns the \fBSoType\fP object associated with objects of this class\&. .SS "\fBSoType\fP SoVRMLCollision::getTypeId (void ) const\fR [virtual]\fP" Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&.
