Attributes to control how a Mesh is made into a collider.
Can be applied to only a USDGeomMesh in addition to its PhysicsCollisionAPI.
For any described attribute Fallback Value or Allowed Values below that are text/tokens, the actual token is published and defined in UsdPhysicsTokens. So to set an attribute to the value "rightHanded", use UsdPhysicsTokens->rightHanded as the value.

inlineexplicit |
Construct a UsdPhysicsMeshCollisionAPI on UsdPrim prim
.
Equivalent to UsdPhysicsMeshCollisionAPI::Get(prim.GetStage(), prim.GetPath()) for a valid prim
, but will not immediately throw an error for an invalid prim
Definition at line 59 of file meshCollisionAPI.h.
|
inlineexplicit |
Construct a UsdPhysicsMeshCollisionAPI on the prim held by schemaObj
.
Should be preferred over UsdPhysicsMeshCollisionAPI(schemaObj.GetPrim()), as it preserves SchemaBase state.

Destructor.

Returns the kind of schema this class belongs to.
Reimplemented from UsdAPISchemaBase.
|
static |
Applies this single-apply API schema to the given prim
.
This information is stored by adding "PhysicsMeshCollisionAPI" to the token-valued, listOp metadata apiSchemas on the prim.
|
static |
Returns true if this single-apply API schema can be applied to the given prim
.
If this schema can not be a applied to the prim, this returns false and, if provided, populates whyNot
with the reason it can not be applied.
Note that if CanApply returns false, that does not necessarily imply that calling Apply will fail. Callers are expected to call CanApply before calling Apply if they want to ensure that it is valid to apply a schema.

bool | writeSparsely = false |

See GetApproximationAttr(), and also Create vs Get Property Methods for when to use Get vs Create.
If specified, author defaultValue
as the attribute's default, sparsely (when it makes sense to do so) if writeSparsely
is true
- the default for writeSparsely
is false
.

static |
Return a UsdPhysicsMeshCollisionAPI holding the prim adhering to this schema at path
on stage
.
If no prim exists at path
on stage
, or if the prim at that path does not adhere to this schema, return an invalid schema object. This is shorthand for the following:
USDPHYSICS_API UsdAttribute GetApproximationAttr | ( | ) | const |
Determines the mesh's collision approximation: "none" - The mesh geometry is used directly as a collider without any approximation.
"convexDecomposition" - A convex mesh decomposition is performed. This results in a set of convex mesh colliders. "convexHull" - A convex hull of the mesh is generated and used as the collider. "boundingSphere" - A bounding sphere is computed around the mesh and used as a collider. "boundingCube" - An optimally fitting box collider is computed around the mesh. "meshSimplification" - A mesh simplification step is performed, resulting in a simplified triangle mesh collider.
Declaration | uniform token physics:approximation = "none" |
C++ Type | TfToken |
Usd Type | SdfValueTypeNames->Token |
Variability | SdfVariabilityUniform |
Allowed Values | none, convexDecomposition, convexHull, boundingSphere, boundingCube, meshSimplification |
|
static |
Return a vector of names of all pre-declared attributes for this schema class and all its ancestor classes.
Does not include attributes that may be authored by custom/extended methods of the schemas involved.
