Reimplemented from OdGiIntersectionsCalculator.

◆ getCalcDistance()

bool OdGiCollisionDetector::getCalcDistance ( ) const
inline

Checks whether collision detection calculates collision distance.

Returns
true if collision detection calculates collision distance, false otherwise.

Definition at line 320 of file GiIntersectionsCalculator.h.

◆ getCheckAll()

bool OdGiCollisionDetector::getCheckAll ( ) const
inline

Checks whether collision detection checks all faces instead of detecting the first collision.

Returns
true if collision detection checks all faces, false otherwise.

Definition at line 333 of file GiIntersectionsCalculator.h.

◆ getClearance()

double OdGiCollisionDetector::getClearance ( ) const
inline

Retrieves a distance for the clearance mode when objects that are "too close" are detected as intersections.

Definition at line 307 of file GiIntersectionsCalculator.h.

◆ getCollisionDistance()

bool OdGiCollisionDetector::getCollisionDistance ( OdInt64  collisionIndex,
double &  result 
) const

Retrieves a collision distance at the specified index.

Parameters
collisionIndex[in] Index of a collision for which to get the distance.
result[out] Receives collision distance.
Returns
true if collision distance is sucessfully received. This method returns false if index exceeds the size of vector with collisions or if collision at the specified index is not detected.

◆ isClearance()

bool OdGiCollisionDetector::isClearance ( ) const
inline

Checks whether clearance mode for detecting collisions is enabled. This method detects collisions between intersectiong, touching and objects that are "too close".

Returns

Definition at line 326 of file GiIntersectionsCalculator.h.

◆ setClearance()

void OdGiCollisionDetector::setClearance ( double  cl)
inline

Specifies a distance for the clearance mode when objects that are "too close" are detected as intersections.

Parameters
cl[in] Clearance distance. Object which have less distance than this value are considered collided in the clearance mode.
