Emission Angle: The angle between the surface normal vector at the intersection point and the vector from the intersection point to the observer (usually the spacecraft). The emission angle varies from 0 degrees when the observer is viewing the sub-spacecraft point (nadir viewing) to 90 degrees when the intercept is tangent to the surface of the target body. Thus, higher values of emission angle indicate more oblique viewing of the target.

Parameters

◆ intersectSurface() [1/3]

bool Isis::DemShape::intersectSurface	(	std::vector< double >	observerPos,
		std::vector< double >	lookDirection
	)

virtual

Find the intersection point with the DEM.

TIDBIT: From the code below we have historically tested to see if we can first intersect the ellipsoid. If not then we assumed that we could not intersect the DEM. This of course isn't always true as the DEM could be above the surface of the ellipsoid. For most images we really wouldn't notice. It has recently (Aug 2011) come into play trying to intersect images containing a limb and spiceinit'ed with a DEM (e.g., Vesta and soon Mercury). This implies that info at the limb will not always be computed. In the future we may want to do a better job handling this special case.

Parameters

observerPos
lookDirection

Returns: bool Indicates whether the intersection was found.

Compute surface intersection with optional occlusion check.

This method sets the surface point at the given latitude, longitude. The derived model is called to get the radius at that location to complete the accuracy of the surface point, them the derived method is called to complete the intersection.

◆ isDEM()

bool Isis::DemShape::isDEM ( ) const

◆ isVisibleFrom()

bool Isis::ShapeModel::isVisibleFrom	(	const std::vector< double >	observerPos,
		const std::vector< double >	lookDirection
	)

virtualinherited

Default occulsion implementation.

This method is originally copied from Sensor::SetLocalGround(bool backCheck). This version checks for the emission angle from the observer to be less than or equal to 90 degrees.

It is recommended that models derived from this base class reimplement this method if a more robust, efficent test can be made.

Note this implementation does not handle occlusion!

Parameters

observerPos	Position of the observer in body fixed coordinates
