Member Function Documentation

check()

bool coal::ContactPatchResult::check ( const ContactPatchRequest &  request ) const

inline

Return true if this ContactPatchResult is aligned with the ContactPatchRequest given as input.

Definition at line 931 of file coal/collision_data.h.

clear()

void coal::ContactPatchResult::clear ( )

inline

Clears the contact patch result.

Definition at line 910 of file coal/collision_data.h.

contactPatch()

ContactPatch& coal::ContactPatchResult::contactPatch ( const size_t  i )

inline

Getter for the i-th contact patch of the result.

Definition at line 896 of file coal/collision_data.h.

getContactPatch()

const ContactPatch& coal::ContactPatchResult::getContactPatch ( const size_t  i ) const

inline

Const getter for the i-th contact patch of the result.

Definition at line 882 of file coal/collision_data.h.

getUnusedContactPatch()

ContactPatchRef coal::ContactPatchResult::getUnusedContactPatch ( )

inline

Returns a new unused contact patch from the internal data vector.

Definition at line 862 of file coal/collision_data.h.

numContactPatches()

size_t coal::ContactPatchResult::numContactPatches ( ) const

inline

Number of contact patches in the result.

Definition at line 859 of file coal/collision_data.h.

operator==()

bool coal::ContactPatchResult::operator== ( const ContactPatchResult &  other ) const

inline

Whether two ContactPatchResult are identical or not.

Definition at line 948 of file coal/collision_data.h.

set()

void coal::ContactPatchResult::set ( const ContactPatchRequest &  request )

inline

Set up a ContactPatchResult from a ContactPatchRequest

Definition at line 919 of file coal/collision_data.h.

swapObjects()

void coal::ContactPatchResult::swapObjects ( )

inline

Member Data Documentation

m_contact_patches

ContactPatchRefVector coal::ContactPatchResult::m_contact_patches

protected

Vector of contact patches of the result.

Definition at line 842 of file coal/collision_data.h.

m_contact_patches_data

ContactPatchVector coal::ContactPatchResult::m_contact_patches_data

protected

Data container for the vector of contact patches.

Note

Contrary to CollisionResult or DistanceResult, which have a very small memory footprint, contact patches can contain relatively large polytopes. In order to reuse a ContactPatchResult while avoiding successive mallocs, we have a data container and a vector which points to the currently active patches in this data container.

Definition at line 834 of file coal/collision_data.h.

m_id_available_patch

size_t coal::ContactPatchResult::m_id_available_patch

protected

Contact patches in m_contact_patches_data can have two statuses: used or unused. This index tracks the first unused patch in the m_contact_patches_data vector.
