Trimesh class

Trimesh. @example // How to make a mesh with a single triangle final vertices = 0, 0, 0, // vertex 0 1, 0, 0, // vertex 1 0, 1, 0 // vertex 2 final indices = 0, 1, 2 // triangle 0 final trimeshShape = CANNON.Trimesh(vertices, indices)

Trimesh.createTorus(TorusGeometry torus): Create a Trimesh instance, shaped as a torus.

Properties

aabb → AABB: The local AABB of the mesh.
final
body ↔ Body?: The body to which the shape is added to.
getter/setter pairinherited
boundingSphereRadius ↔ double: The local bounding sphere radius of this shape.
getter/setter pairinherited
collisionFilterGroup ↔ int: getter/setter pairinherited
collisionFilterMask ↔ int: getter/setter pairinherited
collisionResponse ↔ bool: Whether to produce contact forces when in contact with other bodies. Note that contacts will be generated, but they will be disabled.
getter/setter pairinherited
edges ↔ List<int>: References to vertex pairs, making up all unique edges in the trimesh.
getter/setter pair
faceNormals ↔ List<double>: latefinal
hashCode → int: The hash code for this object.
no setterinherited
id ↔ int: Identifier of the Shape.
getter/setter pairinherited
indices ↔ List<int>: Array of integers, indicating which vertices each triangle consists of. The length of this array is thus 3 times the number of triangles.
latefinal
material ↔ Material?: Optional material of the shape that regulates contact properties.
getter/setter pairinherited
normals ↔ List<double>?: latefinal
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
scale → Vec3: Local scaling of the mesh. Use .setScale() to set it.
final
torus ↔ TorusGeometry: latefinal
tree → Octree: The indexed triangles. Use .updateTree() to update it.
final
type ↔ ShapeType: The type of this shape. Must be set to an int > 0 by subclasses.

uvs ↔ List<double>?: latefinal
vertices ↔ List<double>: latefinal
