Mesh

Inherits: Resource < Reference < Object

Inherited By: ArrayMesh, PrimitiveMesh

A Resource that contains vertex array-based geometry.

Description

Mesh is a type of Resource that contains vertex array-based geometry, divided in surfaces. Each surface contains a completely separate array and a material used to draw it. Design wise, a mesh with multiple surfaces is preferred to a single surface, because objects created in 3D editing software commonly contain multiple materials.

Property Descriptions

Default Vector2( 0, 0 )
Setter set_lightmap_size_hint(value)
Getter get_lightmap_size_hint()

Sets a hint to be used for lightmap resolution in BakedLightmap. Overrides BakedLightmap.bake_default_texels_per_unit.

Method Descriptions

  • Shape create_convex_shape ( ) const

Calculate a ConvexPolygonShape from the mesh.


Calculate an outline mesh at a defined offset (margin) from the original mesh.

Note: This method typically returns the vertices in reverse order (e.g. clockwise to counterclockwise).


  • Shape create_trimesh_shape ( ) const

Calculate a ConcavePolygonShape from the mesh.


Generate a TriangleMesh from the mesh.


  • AABB get_aabb ( ) const

Returns the smallest AABB enclosing this mesh. Not affected by custom_aabb.

Note: This is only implemented for ArrayMesh and PrimitiveMesh.


Returns all the vertices that make up the faces of the mesh. Each three vertices represent one triangle.


  • int get_surface_count ( ) const

Returns the amount of surfaces that the Mesh holds.


  • Array surface_get_arrays ( int surf_idx ) const

Returns the arrays for the vertices, normals, uvs, etc. that make up the requested surface (see ArrayMesh.add_surface_from_arrays).


  • Array surface_get_blend_shape_arrays ( int surf_idx ) const

Returns the blend shape arrays for the requested surface.


Returns a Material in a given surface. Surface is rendered using this material.


  • void surface_set_material ( int surf_idx, Material material )

Sets a Material for a given surface. Surface will be rendered using this material.
