Enum ncollide2d::world::GeometricQueryType
[−]
[src]
pub enum GeometricQueryType<N: Real> { Contacts(N, N), Proximity(N), }
The kind of query a CollisionObject may be involved on.
The following queries are executed for a given pair of GeometricQueryType
associated with two
collision objects:
- Contacts + Contacts = exact contact point coputation.
- Contacts + Proximity = proximity test only.
- Proximity + Proximity = proximity test only.
Variants
Contacts(N, N)
This objects can respond to both contact point computation and proximity queries.
Proximity(N)
This object can respond to proximity tests only.
Methods
impl<N: Real> GeometricQueryType<N>
[src]
pub fn query_limit(&self) -> N
[src]
The numerical distance limit of relevance for this query.
If two objects are separated by a distance greater than the sum of their respective
query_limit
, the corresponding query will not by performed. For proximity queries,
non-intersecting object closer than a distance equal to the sum of their query_limit
will
be reported as Proximity::WithinMargin
.
pub fn contact_queries_to_prediction(
self,
other: Self
) -> Option<ContactPrediction<N>>
[src]
self,
other: Self
) -> Option<ContactPrediction<N>>
Given two contact query types, returns the corresponding contact prediction parameters.
Returns None
if any of self
or other
is not a GeometricQueryType::Contacts
.
pub fn is_contacts_query(&self) -> bool
[src]
Returns true
if this is a contacts query type.
pub fn is_proximity_query(&self) -> bool
[src]
Returns true
if this is a proximity query type.
