GetFeatureIdFromRaycastHit()

Int64 CesiumForUnity.CesiumPrimitiveFeatures.GetFeatureIdFromRaycastHit ( RaycastHit hitInfo, Int64 featureIdSetIndex = 0 )

inline

Gets the feature ID from the given raycast hit, assuming it has hit a glTF primitive component containing this CesiumPrimitiveFeatures.

A primitive may have multiple feature ID sets, so this allows a feature ID set to be specified by index. This value should index into the array of CesiumFeatureIdSets in the CesiumPrimitiveFeatures. If the specified feature ID set index is invalid, this returns -1.

Parameters

hitInfo	The raycast hit info.
featureIdSetIndex	The index of the target feature ID set.

Returns

The feature ID, or -1 if the specified feature ID set is invalid.

Definition at line 115 of file CesiumPrimitiveFeatures.cs.

GetFeatureIdFromTriangle()

Int64 CesiumForUnity.CesiumPrimitiveFeatures.GetFeatureIdFromTriangle ( int triangleIndex, Int64 featureIdSetIndex = 0 )

inline

Gets the feature ID associated with the given triangle, specified by index.

A primitive may have multiple feature ID sets, so this allows a feature ID set to be specified by index.This value should index into the array of CesiumFeatureIdSets in the CesiumPrimitiveFeatures. If the specified feature ID set index is invalid, this returns -1.

Parameters

triangleIndex	The index of the target triangle.
featureIdSetIndex	The index of the target feature ID set.

Returns

The feature ID, or -1 if the specified triangle or feature ID set is invalid.

Definition at line 88 of file CesiumPrimitiveFeatures.cs.

GetFeatureIdSetsOfType()

CesiumFeatureIdSet[] CesiumForUnity.CesiumPrimitiveFeatures.GetFeatureIdSetsOfType ( CesiumFeatureIdSetType type )

inline

Gets all the feature ID sets of the given type.

If the primitive has no sets of that type, the returned array will be empty.

Parameters

type	The desired feature ID set type.

Returns

An array of feature ID sets of the specified type, if any exist on the CesiumPrimitiveFeatures.

GetFirstVertexFromHitTriangle()

static int CesiumForUnity.CesiumPrimitiveFeatures.GetFirstVertexFromHitTriangle ( RaycastHit hitInfo )

inlinestatic

Given a successful raycast hit, finds the index of the first vertex from the hit triangle.

Parameters

hitInfo

The raycast hit.

Returns

The index of the first vertex on the triangle, or -1 if the hit was unsuccessful.
