Mesh

    Inherited By: , PrimitiveMesh

    A that contains vertex array-based geometry.

    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.

    Methods

    enum PrimitiveType:

    • PRIMITIVE_POINTS = 0 —- Render array as points (one vertex equals one point).

    • PRIMITIVE_TRIANGLE_STRIP = 5 —- Render array as triangle strips.
    • PRIMITIVE_TRIANGLE_FAN = 6 —- Render array as triangle fans.

    enum BlendShapeMode:

    • BLEND_SHAPE_MODE_NORMALIZED = 0 —- Blend shapes are normalized.

    Property Descriptions

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

    • create_convex_shape ( ) const

    Calculate a ConvexPolygonShape from the 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).

    • create_trimesh_shape ( ) const

    Calculate a ConcavePolygonShape from the mesh.

    • generate_triangle_mesh ( ) const

    Generate a TriangleMesh from the mesh.

    • get_aabb ( ) const

    Note: This is only implemented for ArrayMesh and .

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

    • get_surface_count ( ) const

    Returns the amount of surfaces that the holds.

    • Array surface_get_arrays ( surf_idx ) const

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

    • surface_get_blend_shape_arrays ( int surf_idx ) const

    Returns the blend shape arrays for the requested surface.

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

    • void surface_set_material ( int surf_idx, material )
