10 <h1>[name]</h1>

12 <div class="desc">
13 This is a superefficent class for geometries because it saves all data in buffers. <br />
14 It reduces memory costs and cpu cycles. But it is not as easy to work with because of all the necessary buffer calculations.<br />
15 It is mainly interesting when working with static objects.
16 </div>

19 <h2>Constructor</h2>
20
21
22 <h3>[name]()</h3>
23 <div>
24 This creates a new [name]. It also sets several properties to an default value.
25 </div>
26
27
28 <h2>Properties</h2>
29
30 <h3>.[page:Integer id]</h3>
31 <div>
32 Unique number of this buffergeometry instance
33 </div>
34
35 <h3>.[page:Hashmap attributes]</h3>
36 <div>
37 This hashmap has as id the name of the attribute to be set and as value the buffer to set it to.
38 </div>
39
40 <h3>.[page:Boolean dynamic]</h3>
41 <div>
42 When set, it holds certain buffers in memory to have faster updates for this object. When unset, it deletes those buffers and saves memory.
43 </div>
44
45 <h3>.[page:Array offsets]</h3>
46 <div>
47 This Array should contain every offset at which the buffers should be rendered. This is important for indexed buffers.
48 </div>
49
50 <h3>.[page:Object boundingBox]</h3>
51 <div>
52 Bounding box.
53 <code>{ min: new THREE.Vector3(), max: new THREE.Vector3() }</code>
54 </div>
55
56 <h3>.[page:Object boundingSphere]</h3>
57 <div>
58 Bounding sphere.
59 <code>{ radius: float }</code>
60 </div>
61
62 <h3>.[page:Array morphTargets]</h3>
63 <div>
64 Array of morph targets. Each morph target is a Javascript object:
65 <code>{ name: "targetName", vertices: [ new THREE.Vertex(), ... ] }</code>
66 Morph vertices match number and order of primary vertices.
67 </div>
68
69 <h3>.[page:boolean hasTangents]</h3>
70 <div>
71 todo
72 </div>
73
74 <h2>Methods</h2>
75
76 <h3>[page:EventDispatcher EventDispatcher] methods are available on this class.</h3>
77
78 <h3>.applyMatrix( [page:Matrix4 matrix] )</h3>
79 <div>
80 Bakes matrix transform directly into vertex coordinates.
81 </div>
82
83 <h3>.computeVertexNormals()</h3>
84 <div>
85 Computes vertex normals by averaging face normals.<br />
86 </div>
87
88 <h3>.computeTangents()</h3>
89 <div>
90 Computes vertex tangents.<br />
91 Based on [link:http://www.terathon.com/code/tangent.html]<br />
92 Geometry must have vertex [page:UV UVs] (layer 0 will be used).
93 </div>
94
95 <h3>.computeBoundingBox()</h3>
96 <div>
97 Computes bounding box of the geometry, updating [page:Geometry Geometry.boundingBox] attribute.<br />
98 Bounding boxes aren't computed by default. They need to be explicitly computed, otherwise they are *null*.
99 </div>
100
101 <h3>.computeBoundingSphere()</h3>
102 <div>
103 Computes bounding sphere of the geometry, updating [page:Geometry Geometry.boundingSphere] attribute.<br />
104 Bounding spheres aren't computed by default. They need to be explicitly computed, otherwise they are *null*.
105 </div>
106
107 <h3>.dispose()</h3>
108 <div>
109 Disposes the object from memory. <br />
110 You need to call this when you want the bufferGeometry removed while the application is running.
111 </div>
112
113 <h3>.normalizeNormals() [page:todo]</h3>
114 <div>
115 todo
116 </div>
