| Description: The sphere_intersection_count attribute specifies the number of the intersection to use for the spherical surface model when the camera is outside the sphere. For example, specifying a value of 1 would indicate the first intersection with the sphere should be used (more useful for modeling hills or rocks), while a value of 2 would indicate the second intersection with the sphere should be used (more useful for modeling craters). In PDS3, this was overloaded as part of the SURFACE_MODEL_TYPE keyword. |
