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 LOD { exposedField MFNode level [] field SFVec3f center 0 0 0 # (-,) field MFFloat range [] # (0,) } .fi .PP .PP The LOD node specifies various levels of detail or complexity for a given object, and provides hints allowing browsers to automatically choose the appropriate version of the object based on the distance from the user\&. The level field contains a list of nodes that represent the same object or objects at varying levels of detail, ordered from highest level of detail to the lowest level of detail\&. The range field specifies the ideal distances at which to switch between the levels\&. Subclause 4\&.6\&.5, Grouping and children nodes (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.5), contains details on the types of nodes that are legal values for level\&. .PP The center field is a translation offset in the local coordinate system that specifies the centre of the LOD node for distance calculations\&. .PP The number of nodes in the level field shall exceed the number of values in the range field by one (i\&.e\&., N+1 level values for N range values)\&. The range field contains monotonic increasing values that shall be greater than zero\&. In order to calculate which level to display, first the distance is calculated from the viewer's location, transformed into the local coordinate system of the LOD node (including any scaling transformations), to the center point of the LOD node\&. Then, the LOD node evaluates the step function L(d) to choose a level for a given value of d (where d is the distance from the viewer position to the centre of the LOD node)\&. Let n ranges, R0, R1, R2, \&.\&.\&., Rn-1, partition the domain (0, +infinity) into n+1 subintervals given by (0, R0), [R0, R1)\&.\&.\&. , [Rn-1, +infinity)\&. Also, let n levels L0, L1, L2, \&.\&.\&., Ln-1 be the values of the step function function L(d)\&. The level node, L(d), for a given distance d is defined as follows: .PP .PP .nf L(d) = L0, if d < R0, = Li+1, if Ri <= d < Ri+1, for -1 < i < n-1, = Ln-1, if d >= Rn-1\&. .fi .PP .PP Specifying too few levels will result in the last level being used repeatedly for the lowest levels of detail\&. If more levels than ranges are specified, the extra levels are ignored\&. An empty range field is an exception to this rule\&. This case is a hint to the browser that it may choose a level automatically to maintain a constant display rate\&. Each value in the range field shall be greater than the previous value\&. .PP LOD nodes are evaluated top-down in the scene graph\&. Only the descendants of the currently selected level are rendered\&. All nodes under an LOD node continue to receive and send events regardless of which LOD node's level is active\&. For example, if an active TimeSensor node is contained within an inactive level of an LOD node, the TimeSensor node sends events regardless of the LOD node's state\&. .SH "Constructor & Destructor Documentation" .PP .SS "SoVRMLLOD::SoVRMLLOD (\fBvoid\fP)" Constructor\&. .SS "SoVRMLLOD::SoVRMLLOD (int levels)" Constructor\&. \fIlevels\fP is the expected number of levels\&. .SS "SoVRMLLOD::~SoVRMLLOD ()\fC [protected]\fP, \fC [virtual]\fP" Destructor\&. .SH "Member Function Documentation" .PP .SS "\fBSoType\fP SoVRMLLOD::getClassTypeId (\fBvoid\fP)\fC [static]\fP" This static method returns the \fBSoType\fP object associated with objects of this class\&. .br .SS "\fBSoType\fP SoVRMLLOD::getTypeId (\fBvoid\fP) const\fC [virtual]\fP" Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&.
