Detailed Description

Pick task context params.

This contains task params that can't come from the scene delegate (like resolution mode and pick location, that might be resolved late), as well as the picking collection and the output hit vector. 'pickTarget': The target of the pick operation, which may influence the data filled in the HdxPickHit(s). The available options are: HdxPickTokens->pickPrimsAndInstances HdxPickTokens->pickFaces HdxPickTokens->pickEdges HdxPickTokens->pickPoints HdxPickTokens->pickPointsAndInstances

'resolveMode': Dictates the resolution of which hit(s) are returned in 'outHits'. The available options are:

  1. HdxPickTokens->resolveNearestToCamera : Returns the hit whose position is nearest to the camera
  2. HdxPickTokens->resolveNearestToCenter : Returns the hit whose position is nearest to center of the pick location/region.
  3. HdxPickTokens->resolveUnique : Returns the unique hits, by hashing the relevant member fields of HdxPickHit. The 'pickTarget' influences this operation. For e.g., the subprim indices are ignored when the pickTarget is pickPrimsAndInstances.
  4. HdxPickTokens->resolveAll: Returns all the hits for the pick location or region. The number of hits returned depends on the resolution used and may have duplicates.
  5. HdxPickTokens->resolveDeep: Returns the unique hits not only of visible geometry but also of all the geometry hiding behind. The 'pickTarget' influences this operation. For e.g., the subprim indices are ignored when the pickTarget is pickPrimsAndInstances.
