Required methods
pub fn compute_aabb(&self, position: &Isometry<f32>) -> AABB<f32>
[src]
Computes the AABB of this shape.
pub fn mass_properties(&self, density: f32) -> MassProperties
[src]
Compute the mass-properties of this shape given its uniform density.
pub fn shape_type(&self) -> ShapeType
[src]
Gets the type tag of this shape.
Implementations
impl dyn Shape
[src]
pub fn is<__T: Shape>(&self) -> bool
[src]
Returns true if the trait object wraps an object of type __T
.
pub fn downcast<__T: Shape>(self: Box<Self>) -> Result<Box<__T>, Box<Self>>
[src]
Returns a boxed object from a boxed trait object if the underlying object is of type
__T
. Returns the original boxed trait if it isn't.
pub fn downcast_rc<__T: Shape>(self: Rc<Self>) -> Result<Rc<__T>, Rc<Self>>
[src]
Returns an Rc
-ed object from an Rc
-ed trait object if the underlying object is of
type __T
. Returns the original Rc
-ed trait if it isn't.
pub fn downcast_ref<__T: Shape>(&self) -> Option<&__T>
[src]
Returns a reference to the object within the trait object if it is of type __T
, or
None
if it isn't.
pub fn downcast_mut<__T: Shape>(&mut self) -> Option<&mut __T>
[src]
Returns a mutable reference to the object within the trait object if it is of type
__T
, or None
if it isn't.
pub fn downcast_arc<__T: Shape>(self: Arc<Self>) -> Result<Arc<__T>, Arc<Self>> where
__T: Any + Send + Sync,
[src]
__T: Any + Send + Sync,
Returns an Arc
-ed object from an Arc
-ed trait object if the underlying object is of
type __T
. Returns the original Arc
-ed trait if it isn't.

pub fn as_heightfield(&self) -> Option<&HeightField>
[src]
Converts this abstract shape to a heightfield, if it is one.
