TorusKnotGeometry class

Creates a torus knot, the particular shape of which is defined by a pair of coprime integers, p and q. If p and q are not coprime, the result will be a torus link.

final geometry = TorusKnotGeometry( 10, 3, 100, 16 ); 
final material = MeshBasicMaterial( { MaterialProperty.color: 0xffff00}); 
final circle = Mesh(geometry, material); 
scene.add(circle);

Methods

addEventListener(String type, Function listener) → void
type - The type of event to listen to.
inherited
addGroup(int start, int count, [int materialIndex = 0]) → void
Adds a group to this geometry; see the groups property for details.
inherited
applyMatrix4(Matrix4 matrix) → void
Applies the matrix transform to the geometry.
inherited
applyQuaternion(Quaternion q) → BufferGeometry
Applies the rotation represented by the quaternion to the geometry.
inherited
center() → void
Center the geometry based on the bounding box.
inherited
clearGroups() → void
Clears all groups.
inherited
clearListeners() → void
Remove all Listeners.
inherited
clone() → BufferGeometry
Creates a clone of this BufferGeometry.
inherited
computeBoundingBox() → void
inherited
computeBoundingSphere() → void
Computes the bounding sphere of the geometry, and updates the boundingSphere attribute.
inherited
computeFaceNormals() → void
inherited
computeTangents() → void
Calculates and adds a tangent attribute to this geometry.
inherited
computeVertexNormals() → void
Computes vertex normals for the given vertex data. For indexed geometries, the method sets each vertex normal to be the average of the face normals of the faces that share that vertex.
inherited
copy(BufferGeometry source) → BufferGeometry
inherited
deleteAttribute(Attribute type) → BufferGeometry
Deletes the type with the specified Attribute.
inherited
deleteAttributeFromString(String type) → BufferGeometry
Deletes the type with the specified string name.
inherited
dispatchEvent(Event event) → void
event - The event that gets fired.
inherited
dispose() → void
Frees the GPU-related resources allocated by this instance. Call this method whenever this instance is no longer used in your app.
inherited
getAttribute(Attribute type) → dynamic
Returns the type with the specified Attribute.
inherited
getAttributeFromString(String type) → dynamic
Returns the type with the specified string name.
inherited
getIndex() → BufferAttribute<NativeArray<num>>?
Return the index buffer.
inherited
hasAttribute(Attribute type) bool
Returns true if the attribute with the specified name exists.
inherited
hasAttributeFromString(String type) bool
Returns true if the attribute with the specified name exists.
inherited
hasEventListener(String type, Function listener) bool
type - The type of event to listen to.
inherited
lookAt(Vector3 vector) → BufferGeometry
vector - A world vector to look at.
inherited
merge(BufferGeometry geometry, [int? offset]) → BufferGeometry
inherited
normalizeNormals() → void
Every normal vector in a geometry will have a magnitude of 1. This will correct lighting on the geometry surfaces.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeEventListener(String type, Function listener) → void
type - The type of the listener that gets removed.
inherited
rotateX(double angle) → BufferGeometry
Rotate the geometry about the X axis. This is typically done as a one time operation, and not during a loop. Use rotation for typical real-time mesh rotation.
inherited
rotateY(double angle) → BufferGeometry
Rotate the geometry about the Y axis. This is typically done as a one time operation, and not during a loop. Use rotation for typical real-time mesh rotation.
inherited
rotateZ(double angle) → BufferGeometry
Rotate the geometry about the Z axis. This is typically done as a one time operation, and not during a loop. Use rotation for typical real-time mesh rotation.
inherited
scale(double x, double y, double z) → BufferGeometry
Scale the geometry data. This is typically done as a one time operation, and not during a loop. Use scale for typical real-time mesh scaling.
inherited
setAttribute(Attribute type, dynamic attribute) → BufferGeometry
Sets an attribute to this geometry. Use this rather than the attributes property, because an internal hashmap of attributes is maintained to speed up iterating over attributes.
inherited
setAttributeFromString(String type, dynamic source) → BufferGeometry
Sets an attribute to this geometry. Use this rather than the attributes property, because an internal hashmap of attributes is maintained to speed up iterating over attributes.
inherited
setDrawRange(int start, int count) → void
Set the drawRange property. For non-indexed BufferGeometry, count is the number of vertices to render. For indexed BufferGeometry, count is the number of indices to render.
inherited
setFromPoints(dynamic points) → BufferGeometry
Sets the attributes for this BufferGeometry from an array of points.
inherited
setIndex(dynamic index) → void
inherited
toJson({Object3dMeta? meta}) Map<String, dynamic>
Convert the buffer geometry to three.js JSON Object/Scene format.
inherited
toNonIndexed() → BufferGeometry
Return a non-index version of an indexed BufferGeometry.
inherited
toString() String
A string representation of this object.
inherited
translate(double x, double y, double z) → BufferGeometry
Translate the geometry by x,y,z. This is typically done as a one time operation, and not during a loop. Use position for typical real-time mesh translation.
inherited
translateWithVector3(Vector3 v3) → BufferGeometry
Translate the geometry by Vecotr3. This is typically done as a one time operation, and not during a loop. Use position for typical real-time mesh translation.
