ViewportInfo.GetPointDepth Method

ViewportInfoGetPointDepth Method

Gets the clipping distance of a point. This function ignores the current value of the viewport's near and far settings. If the viewport is a perspective projection, then it intersects the semi infinite frustum volume with the bounding box and returns the near and far distances of the intersection. If the viewport is a parallel projection, it instersects the infinte view region with the bounding box and returns the near and far distances of the projection.

	point As Point3d,
	<OutAttribute> ByRef distance As Double
) As Boolean

Parameters

point
Type: Rhino.GeometryPoint3d
A point to measure.
distance
Type: SystemDouble
distance of the point (can be < 0)

Return Value

Type: Boolean
true if the bounding box intersects the view frustum and near_dist/far_dist were set. false if the bounding box does not intesect the view frustum.
