Instance members

• func addIndex(Int32)

  Adds a vertex to index array if you are using indexed vertices. Does not need to be called before adding vertices.

• func addTriangleFan(vertices: PackedVector3Array, uvs: PackedVector2Array, colors: PackedColorArray, uv2s: PackedVector2Array, normals: PackedVector3Array, tangents: VariantCollection<Plane>)

  Inserts a triangle fan made of array data into Mesh being constructed.

• func addVertex(Vector3)

  Specifies the position of current vertex. Should be called after specifying other vertex properties (e.g. Color, UV).

• func appendFrom(existing: Mesh?, surface: Int32, transform: Transform3D)

  Append vertices from a given Mesh surface onto the current vertex array with specified Transform3D.

• func begin(primitive: Mesh.PrimitiveType)

  Called before adding any vertices. Takes the primitive type as an argument (e.g. Mesh/PrimitiveType/primitiveTriangles).

• func clear()

  Clear all information passed into the surface tool so far.

• func commit(existing: ArrayMesh?, flags: UInt) -> ArrayMesh?

  Returns a constructed ArrayMesh from current information passed in. If an existing ArrayMesh is passed in as an argument, will add an extra surface to the existing ArrayMesh.

• func commitToArrays() -> GArray

  Commits the data to the same format used by addSurfaceFromArrays(primitive:arrays:blendShapes:lods:flags:). This way you can further process the mesh data using the ArrayMesh API.

• func createFrom(existing: Mesh?, surface: Int32)

  Creates a vertex array from an existing Mesh.

• func createFromBlendShape(existing: Mesh?, surface: Int32, blendShape: String)

  Creates a vertex array from the specified blend shape of an existing Mesh. This can be used to extract a specific pose from a blend shape.

• func deindex()

  Removes the index array by expanding the vertex array.

• func generateLod(ndThreshold: Double, targetIndexCount: Int32) -> PackedInt32Array

  Generates a LOD for a given ndThreshold in linear units (square root of quadric error metric), using at most targetIndexCount indices.

• func generateNormals(flip: Bool)

  Generates normals from vertices so you do not have to do it manually. If flip is true, the resulting normals will be inverted. generateNormals(flip:) should be called after generating geometry and before committing the mesh using commit(existing:flags:) or commitToArrays. For correct display of normal-mapped surfaces, you will also have to generate tangents using generateTangents.

• func generateTangents()

  Generates a tangent vector for each vertex. Requires that each vertex have UVs and normals set already (see generateNormals(flip:)).

• func getAabb() -> AABB

  Returns the axis-aligned bounding box of the vertex positions.

• func getCustomFormat(channelIndex: Int32) -> SurfaceTool.CustomFormat

  Returns the format for custom channelIndex (currently up to 4). Returns .customMax if this custom channel is unused.

• func getPrimitiveType() -> Mesh.PrimitiveType

  Returns the type of mesh geometry, such as Mesh/PrimitiveType/primitiveTriangles.

• func index()

  Shrinks the vertex array by creating an index array. This can improve performance by avoiding vertex reuse.

• func optimizeIndicesForCache()

  Optimizes triangle sorting for performance. Requires that getPrimitiveType is Mesh/PrimitiveType/primitiveTriangles.

• func setBones(PackedInt32Array)

  Specifies an array of bones to use for the next vertex. bones must contain 4 integers.

• func setColor(Color)

  Specifies a Color to use for the next vertex. If every vertex needs to have this information set and you fail to submit it for the first vertex, this information may not be used at all.

• func setCustom(channelIndex: Int32, customColor: Color)

  Sets the custom value on this vertex for channelIndex.

• func setCustomFormat(channelIndex: Int32, format: SurfaceTool.CustomFormat)

  Sets the color format for this custom channelIndex. Use .customMax to disable.

• func setMaterial(Material?)

  Sets Material to be used by the Mesh you are constructing.

• func setNormal(Vector3)

  Specifies a normal to use for the next vertex. If every vertex needs to have this information set and you fail to submit it for the first vertex, this information may not be used at all.

• func setSkinWeightCount(SurfaceTool.SkinWeightCount)

  Set to .skin8Weights to indicate that up to 8 bone influences per vertex may be used.

• func setSmoothGroup(index: UInt32)

  Specifies the smooth group to use for the next vertex. If this is never called, all vertices will have the default smooth group of 0 and will be smoothed with adjacent vertices of the same group. To produce a mesh with flat normals, set the smooth group to -1.

• func setTangent(Plane)

  Specifies a tangent to use for the next vertex. If every vertex needs to have this information set and you fail to submit it for the first vertex, this information may not be used at all.

• func setUv(Vector2)

  Specifies a set of UV coordinates to use for the next vertex. If every vertex needs to have this information set and you fail to submit it for the first vertex, this information may not be used at all.

• func setUv2(Vector2)

  Specifies an optional second set of UV coordinates to use for the next vertex. If every vertex needs to have this information set and you fail to submit it for the first vertex, this information may not be used at all.

• func setWeights(PackedFloat32Array)

  Specifies weight values to use for the next vertex. weights must contain 4 values. If every vertex needs to have this information set and you fail to submit it for the first vertex, this information may not be used at all.
