Description

The MeshDataTool provides access to individual vertices in a Mesh. It allows users to read and edit vertex data of meshes. It also creates an array of faces and edges.

To use the MeshDataTool, load a mesh with create_from_surface. When you are finished editing the data commit the data to a mesh with commit_to_surface.

Below is an example of how the MeshDataTool may be used.

var mdt = MeshDataTool.new()
mdt.create_from_surface(mesh, 0)
for i in range(mdt.get_vertex_count()):
    var vertex = mdt.get_vertex(i)
    ...
    mdt.set_vertex(i, vertex)
mesh.surface_remove(0)
mdt.commit_to_surface(mesh)

Method Descriptions

void clear ( )

Clears all data currently in MeshDataTool.

Error commit_to_surface ( ArrayMesh mesh )

Adds a new surface to specified Mesh with edited data.

Error create_from_surface ( ArrayMesh mesh, int surface )

Uses specified surface of given Mesh to populate data for MeshDataTool.

Requires Mesh with primitive type Mesh.PRIMITIVE_TRIANGLES.

int get_edge_count ( ) const

Returns the number of edges in this Mesh.

PoolIntArray get_edge_faces ( int idx ) const

Returns array of faces that touch given edge.

Variant get_edge_meta ( int idx ) const

Returns meta information assigned to given edge.

int get_edge_vertex ( int idx, int vertex ) const

Returns index of specified vertex connected to given edge.

Vertex argument can only be 0 or 1 because edges are comprised of two vertices.

int get_face_count ( ) const

Returns the number of faces in this Mesh.

int get_face_edge ( int idx, int edge ) const

Returns specified edge associated with given face.

Edge argument must 2 or less because a face only has three edges.

Variant get_face_meta ( int idx ) const

Returns meta data associated with given face.

Vector3 get_face_normal ( int idx ) const

Calculates and returns face normal of given face.

int get_face_vertex ( int idx, int vertex ) const

Returns specified vertex of given face.

Vertex argument must be 2 or less because faces contain three vertices.

int get_format ( ) const

Returns format of Mesh. Format is an integer made up of Mesh format flags combined together. For example, a mesh containing both vertices and normals would return a format of 3 because ArrayMesh.ARRAY_FORMAT_VERTEX is 1 and ArrayMesh.ARRAY_FORMAT_NORMAL is 2.

For list of format flags see ArrayFormat.

Material get_material ( ) const

Returns material assigned to the Mesh.

Vector3 get_vertex ( int idx ) const

Returns the vertex at given index.

PoolIntArray get_vertex_bones ( int idx ) const

Returns the bones of the given vertex.

Color get_vertex_color ( int idx ) const

Returns the color of the given vertex.

int get_vertex_count ( ) const

Returns the total number of vertices in Mesh.

PoolIntArray get_vertex_edges ( int idx ) const

Returns array of edges that share given vertex.

PoolIntArray get_vertex_faces ( int idx ) const

Returns array of faces that share given vertex.

Variant get_vertex_meta ( int idx ) const

Returns meta data associated with given vertex.

Vector3 get_vertex_normal ( int idx ) const

Returns normal of given vertex.

Plane get_vertex_tangent ( int idx ) const

Returns tangent of given vertex.

Vector2 get_vertex_uv ( int idx ) const

Returns UV of given vertex.

Vector2 get_vertex_uv2 ( int idx ) const

Returns UV2 of given vertex.

PoolRealArray get_vertex_weights ( int idx ) const

Returns bone weights of given vertex.

void set_edge_meta ( int idx, Variant meta )

Sets the meta data of given edge.

void set_face_meta ( int idx, Variant meta )

Sets the meta data of given face.

void set_material ( Material material )

Sets the material to be used by newly constructed Mesh.

void set_vertex ( int idx, Vector3 vertex )

Sets the position of given vertex.

void set_vertex_bones ( int idx, PoolIntArray bones )

Sets the bones of given vertex.

void set_vertex_color ( int idx, Color color )

Sets the color of given vertex.

void set_vertex_meta ( int idx, Variant meta )

Sets the meta data associated with given vertex.

void set_vertex_normal ( int idx, Vector3 normal )

Sets the normal of given vertex.

void set_vertex_tangent ( int idx, Plane tangent )

Sets the tangent of given vertex.

void set_vertex_uv ( int idx, Vector2 uv )

Sets the UV of given vertex.

void set_vertex_uv2 ( int idx, Vector2 uv2 )

Sets the UV2 of given vertex.

void set_vertex_weights ( int idx, PoolRealArray weights )

Sets the bone weights of given vertex.
