Struct gdnative::api::PrimitiveMesh

pub struct PrimitiveMesh { /* fields omitted */ }

core class PrimitiveMesh inherits Mesh (reference counted).

Official documentation

See the documentation of this class in the Godot engine's official documentation.

Memory management

The lifetime of this object is automatically managed through reference counting.

Class hierarchy

PrimitiveMesh inherits methods from:

• Mesh
• Resource
• Reference
• Object

Safety

All types in the Godot API have "interior mutability" in Rust parlance. To enforce that the official thread-safety guidelines are followed, the typestate pattern is used in the Ref and TRef smart pointers, and the Instance API. The typestate Access in these types tracks whether the access is unique, shared, or exclusive to the current thread. For more information, see the type-level documentation on Ref.

Implementations

impl PrimitiveMesh

pub fn custom_aabb(&self) -> Aabb

Overrides the [AABB] with one defined by user for use with frustum culling. Especially useful to avoid unnexpected culling when  using a shader to offset vertices.

pub fn flip_faces(&self) -> bool

If set, the order of the vertices in each triangle are reversed resulting in the backside of the mesh being drawn.
			This gives the same result as using [constant SpatialMaterial.CULL_BACK] in [member SpatialMaterial.params_cull_mode].

pub fn material(&self) -> Option<Ref<Material, Shared>>

The current [Material] of the primitive mesh.

pub fn get_mesh_arrays(&self) -> VariantArray<Shared>

Returns mesh arrays used to constitute surface of [Mesh]. The result can be passed to [method ArrayMesh.add_surface_from_arrays] to create a new surface. For example:
				[codeblock]
				var c := CylinderMesh.new()
				var arr_mesh := ArrayMesh.new()
				arr_mesh.add_surface_from_arrays(Mesh.PRIMITIVE_TRIANGLES, c.get_mesh_arrays())
				[/codeblock]

pub fn set_custom_aabb(&self, aabb: Aabb)

Overrides the [AABB] with one defined by user for use with frustum culling. Especially useful to avoid unnexpected culling when  using a shader to offset vertices.

pub fn set_flip_faces(&self, flip_faces: bool)

If set, the order of the vertices in each triangle are reversed resulting in the backside of the mesh being drawn.
			This gives the same result as using [constant SpatialMaterial.CULL_BACK] in [member SpatialMaterial.params_cull_mode].

pub fn set_material(&self, material: impl AsArg<Material>)

The current [Material] of the primitive mesh.

pub fn create_convex_shape(&self) -> Option<Ref<Shape, Shared>>

Calculate a [ConvexPolygonShape] from the mesh.

pub fn create_outline(&self, margin: f64) -> Option<Ref<Mesh, Shared>>

Calculate an outline mesh at a defined offset (margin) from the original mesh.
				[b]Note:[/b] This method typically returns the vertices in reverse order (e.g. clockwise to counterclockwise).

pub fn get_aabb(&self) -> Aabb

Returns the smallest [AABB] enclosing this mesh in local space. Not affected by [code]custom_aabb[/code]. See also [method VisualInstance.get_transformed_aabb].
				[b]Note:[/b] This is only implemented for [ArrayMesh] and [PrimitiveMesh].

pub fn get_faces(&self) -> TypedArray<Vector3D<f32, UnknownUnit>>

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

pub fn lightmap_size_hint(&self) -> Vector2D<f32, UnknownUnit>

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

pub fn get_surface_count(&self) -> i64

Returns the amount of surfaces that the [Mesh] holds.

pub fn set_lightmap_size_hint(&self, size: Vector2D<f32, UnknownUnit>)
