Detailed Description

Linear scaling algorithm implementation This Scaling algorithm implements basic linear scaling.

Objects in the scene are scaled by the scale factor indicated; neither object size or distance from the camera is used.

Calculate the XR scale factor.

This is the method can be overridden to change to a different method. This version will scale based on the distance of the object from the eyepoint, its size, and the scale factor parameter in the cull visitor parameters set.

Parameters

[in]	info	is the cull visitor parameters object, which contains the current XR scale factor setting, as well as other potentially useful information for a scaling algorithm.
[in]	camera	is the current cull or intersector camera, from which the eyepoint can be found, as well as the viewport, model view and projection matrices, if desired.
[in]	position	is the position of the object to be scaled
[in]	modelRadius	is the bounding radius of the object to be scaled
[in]	objectElementId	is the element ID of the object being scaled, if it exists - check first for (DtUniqueID)0.

Returns

the amount to scale the object
