staticboundingRadius(mesh:Mesh):Float
Returns the boundingRadius of an Entity of a Mesh.
Parameters:
mesh | Mesh. The mesh to get the boundingRadius from. |
|---|
staticboundingRadiusContainer(container:ObjectContainer3D):Float
Returns the boundingRadius of a ObjectContainer3D
Parameters:
container | ObjectContainer3D. The ObjectContainer3D and its children to get the boundingRadius from. |
|---|
staticbuild(vertices:Vector<Float>, indices:Vector<UInt>, ?uvs:Vector<Float>, name:String = "", ?material:MaterialBase, shareVertices:Bool = true, useDefaultMap:Bool = true, useCompactSubGeometry:Bool = true):Mesh
Build a Mesh from Vectors @ returns Mesh
Parameters:
vertices | Vector.<Number>. The vertices Vector.<Number>, must hold a multiple of 3 numbers. |
|---|---|
indices | Vector.<uint>. The indices Vector.<uint>, holding the face order |
uvs | [optional] Vector.<Number>. The uvs Vector, must hold a series of numbers of (vertices.length/3 * 2) entries. If none is set, default uv's are applied if no uv's are defined, default uv mapping is set. |
name | [optional] String. new name for the generated mesh. Default = ""; |
material | [optional] MaterialBase. new name for the duplicated mesh. Default = null; |
shareVertices | [optional] Boolean. Defines if the vertices are shared or not. When true surface gets a smoother appearance when exposed to light. Default = true; |
useDefaultMap | [optional] Boolean. Defines if the mesh receives the default engine map if no material is passes. Default = true; |
staticclone(mesh:Mesh, newName:String = ""):Mesh
Clones a Mesh @ returns Mesh
Parameters:
mesh | Mesh. The mesh to clone |
|---|---|
newname | [optional] String. new name for the duplicated mesh. Default = ""; |
staticinvertFaces(mesh:Mesh, invertU:Bool = false):Void
Inverts the faces of a Mesh
Parameters:
mesh | Mesh. The Mesh to invert. |
|---|---|
invertUV | Boolean. If the uvs are inverted too. Default is false; |
staticinvertFacesInContainer(obj:ObjectContainer3D):Void
Inverts the faces of all the Meshes into an ObjectContainer3D
Parameters:
obj | ObjectContainer3D. The ObjectContainer3D to invert. |
|---|
staticrecenter(mesh:Mesh, keepPosition:Bool = true):Void
Recenter geometry
Parameters:
mesh | Mesh. The Mesh to recenter in its own objectspace |
|---|---|
keepPosition | Boolean. KeepPosition applys the offset to the object position. Object is "visually" at same position. |
staticrecenterContainer(obj:ObjectContainer3D, keepPosition:Bool = true):Void
Recenter geometry of all meshes found into container
Parameters:
mesh | Mesh. The Mesh to recenter in its own objectspace |
|---|---|
keepPosition | Boolean. KeepPosition applys the offset to the object position. Object is "visually" at same position. |
staticsplitMesh(mesh:Mesh, disposeSource:Bool = false):Vector<Mesh>
Splits the subgeometries of a given mesh in a series of new meshes @ returns Vector..<Mesh>
Parameters:
mesh | Mesh. The mesh to split in a series of independant meshes from its subgeometries. |
|---|---|
