Readonly_This hashmap has as id the name of the attribute to be set and as value the THREE.BufferAttribute | buffer to set it to. Rather than accessing this property directly, use .setAttribute and .getAttribute to access attributes of this geometry.
ReadonlyboundingBounding box for the THREE.BufferGeometry | BufferGeometry, which can be calculated with .computeBoundingBox().
ReadonlyboundingBounding sphere for the THREE.BufferGeometry | BufferGeometry, which can be calculated with .computeBoundingSphere().
OptionalboundsDetermines the part of the geometry to render. This should not be set directly, instead use .setDrawRange(...).
Split the geometry into groups, each of which will be rendered in a separate WebGL draw call. This allows an array of materials to be used with the geometry.
Unique number for this THREE.BufferGeometry | BufferGeometry instance.
Allows for vertices to be re-used across multiple triangles; this is called using "indexed triangles". Each triangle is associated with the indices of three vertices. This attribute therefore stores the index of each vertex for each triangular face. If this attribute is not set, the THREE.WebGLRenderer | renderer assumes that each three contiguous positions represent a single triangle.
ReadonlyisReadonlyisRead-only flag to check if a given object is of type BufferGeometry.
Hashmap of THREE.BufferAttribute | BufferAttributes holding details of the geometry's morph targets.
Once the geometry has been rendered, the morph attribute data cannot be changed. You will have to call .dispose(), and create a new instance of THREE.BufferGeometry | BufferGeometry.
Used to control the morph target behavior; when set to true, the morph target data is treated as relative offsets, rather than as absolute positions/normals.
Optional name for this THREE.BufferGeometry | BufferGeometry instance.
ReadonlytypeA Read-only string to check if this object type.
An object that can be used to store custom data about the BufferGeometry. It should not hold references to functions as these will not be cloned.
UUID of this object instance.
Adds a listener to an event type.
The type of event to listen to.
The function that gets called when the event is fired.
Adds a group to this geometry
OptionalmaterialIndex: numberthe groups property for details.
Applies the matrix transform to the geometry.
Applies the rotation represented by the quaternion to the geometry.
Center the geometry based on the bounding box.
Clears all groups.
Creates a clone of this BufferGeometry
Computes the bounding box of the geometry, and updates the .boundingBox attribute. The bounding box is not computed by the engine; it must be computed by your app. You may need to recompute the bounding box if the geometry vertices are modified.
Computes the bounding sphere of the geometry, and updates the .boundingSphere attribute. The engine automatically computes the bounding sphere when it is needed, e.g., for ray casting or view frustum culling. You may need to recompute the bounding sphere if the geometry vertices are modified.
Calculates and adds a tangent attribute to this geometry. The computation is only supported for indexed geometries and if position, normal, and uv attributes are defined
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. For non-indexed geometries, vertices are not shared, and the method sets each vertex normal to be the same as the face normal.
Copies another BufferGeometry to this BufferGeometry.
Return the geometry with reference to the main position and normal buffer attributes but with a short copy of the index buffer attribute
Return the .index buffer.
Return the geometry with reference to the main buffer attributes, share the same attributes as the batched Geometry
Checks if listener is added to an event type.
The type of event to listen to.
The function that gets called when the event is fired.
Removes a listener from an event type.
The type of the listener that gets removed.
The listener function that gets removed.
Remove unused values in attributes and index buffer Update vertexRanges and indexRanges with the new ranges Set the geometry id as available
Sets an attribute to this geometry with the specified name.
Use this rather than the attributes property, because an internal hashmap of .attributes is maintained to speed up iterating over attributes.
Set the .drawRange property
is the number of vertices or indices to render. Expects a Integer
Defines a geometry by creating a position attribute based on the given array of points. The array can hold
instances of Vector2 or Vector3. When using two-dimensional data, the z coordinate for all
vertices is set to 0.
If the method is used with an existing position attribute, the vertex data are overwritten with the data from
the array. The length of the array must match the vertex count.
Set the THREE.BufferGeometry.index | .index buffer.
Convert the buffer geometry to three.js JSON Object/Scene format.
Return a non-index version of an indexed BufferGeometry.
