ViewportInfoGetBoundingBoxDepth Method

Gets near and far clipping distances of a bounding box. This function ignores the current value of the viewport's near and far settings. If the viewport is a perspective projection, the 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 intersects the infinite view region with the bounding box and returns the near and far distances of the projection.

Syntax
Copy
public bool GetBoundingBoxDepth(
	BoundingBox bbox,
	out double nearDistance,
	out double farDistance
)

Parameters

bbox
Type: Rhino.GeometryBoundingBox
The bounding box to sample.
nearDistance
Type: SystemDouble
Near distance of the box. This value can be zero or negative when the camera location is inside box.
farDistance
Type: SystemDouble
Far distance of the box. This value can be equal to near_dist, zero or negative when the camera location is in front of the bounding box.

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 intersect the view frustum.
