scaleByDistance

Gets or sets near and far scaling properties of a Billboard based on the billboard's distance from the camera. A billboard's scale will interpolate between the NearFarScalar.nearValue and NearFarScalar.farValue while the camera distance falls within the lower and upper bounds of the specified NearFarScalar.near and NearFarScalar.far. Outside of these ranges the billboard's scale remains clamped to the nearest bound. If undefined, scaleByDistance will be disabled.

// Example 1.
// Set a billboard's scaleByDistance to scale by 1.5 when the
// camera is 1500 meters from the billboard and disappear as
// the camera distance approaches 8.0e6 meters.
b.scaleByDistance = new NearFarScalar(1.5e2, 1.5, 8.0e6, 0.0);

// Example 2.
// disable scaling by distance
b.scaleByDistance = undefined;
