Inherits: Mesh < Resource < Reference < Object
Mesh type that provides utility for constructing a surface from arrays.
The ArrayMesh
is used to construct a Mesh by specifying the attributes as arrays.
The most basic example is the creation of a single triangle:
var vertices = PoolVector3Array() vertices.push_back(Vector3(0, 1, 0)) vertices.push_back(Vector3(1, 0, 0)) vertices.push_back(Vector3(0, 0, 1)) # Initialize the ArrayMesh. var arr_mesh = ArrayMesh.new() var arrays = [] arrays.resize(ArrayMesh.ARRAY_MAX) arrays[ArrayMesh.ARRAY_VERTEX] = vertices # Create the Mesh. arr_mesh.add_surface_from_arrays(Mesh.PRIMITIVE_TRIANGLES, arrays) var m = MeshInstance.new() m.mesh = arr_mesh
The MeshInstance is ready to be added to the SceneTree to be shown.
See also ImmediateGeometry, MeshDataTool and SurfaceTool for procedural geometry generation.
Note: Godot uses clockwise winding order for front faces of triangle primitive modes.

enum ArrayType:
For triangles, the index array is interpreted as triples, referring to the vertices of each triangle. For lines, the index array is in pairs indicating the start and end of each line.
enum ArrayFormat:
Default | 1 |
Setter | set_blend_shape_mode(value) |
Getter | get_blend_shape_mode() |
Sets the blend shape mode to one of BlendShapeMode.
Default | AABB( 0, 0, 0, 0, 0, 0 ) |
Setter | set_custom_aabb(value) |
Getter | get_custom_aabb() |
Overrides the AABB with one defined by user for use with frustum culling. Especially useful to avoid unexpected culling when using a shader to offset vertices.
Adds name for a blend shape that will be added with add_surface_from_arrays. Must be called before surface is added.
Creates a new surface.
Surfaces are created to be rendered using a primitive
, which may be any of the types defined in PrimitiveType. (As a note, when using indices, it is recommended to only use points, lines or triangles.) Mesh.get_surface_count will become the surf_idx
for this new surface.
The arrays
argument is an array of arrays. See ArrayType for the values used in this array. For example, arrays[0]
is the array of vertices. That first vertex sub-array is always required; the others are optional. Adding an index array puts this function into "index mode" where the vertex and other arrays become the sources of data and the index array defines the vertex order. All sub-arrays must have the same length as the vertex array or be empty, except for ARRAY_INDEX if it is used.
Adding an index array puts this function into "index mode" where the vertex and other arrays become the sources of data, and the index array defines the order of the vertices.
Removes all blend shapes from this ArrayMesh
.
Returns the number of blend shapes that the ArrayMesh
holds.
Returns the name of the blend shape at this index.
Will perform a UV unwrap on the ArrayMesh
to prepare the mesh for lightmapping.
Will regenerate normal maps for the ArrayMesh
.
Returns the index of the first surface with this name held within this ArrayMesh
. If none are found, -1 is returned.
Returns the length in indices of the index array in the requested surface (see add_surface_from_arrays).
Returns the length in vertices of the vertex array in the requested surface (see add_surface_from_arrays).
Returns the format mask of the requested surface (see add_surface_from_arrays).
Gets the name assigned to this surface.
Returns the primitive type of the requested surface (see add_surface_from_arrays).
Removes a surface at position surf_idx
, shifting greater surfaces one surf_idx
slot down.
Sets a name for a given surface.
Updates a specified region of mesh arrays on the GPU.
Warning: Only use if you know what you are doing. You can easily cause crashes by calling this function with improper arguments.
