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

• Vector2 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.

• Mesh create_outline ( float margin ) const

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.

• TriangleMesh generate_triangle_mesh ( ) const

Generate a TriangleMesh from the mesh.

• AABB get_aabb ( ) const

Returns the smallest AABB enclosing this mesh in local space. Not affected by custom_aabb. See also VisualInstance.get_transformed_aabb.

Note: This is only implemented for ArrayMesh and PrimitiveMesh.

• PoolVector3Array get_faces ( ) const

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.

• Material surface_get_material ( int surf_idx ) const

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.
