Struct RingMeshBuilder 

pub struct RingMeshBuilder<P>
where
    P: Primitive2d + Meshable,
{
    pub outer_shape_builder: <P as Meshable>::Output,
    pub inner_shape_builder: <P as Meshable>::Output,
}

A builder used for creating a Mesh with a Ring shape.

Fields

outer_shape_builder: <P as Meshable>::Output

inner_shape_builder: <P as Meshable>::Output

Implementations

impl<P> RingMeshBuilder<P>

where P: Primitive2d + Meshable,

pub fn new(ring: &Ring<P>) -> RingMeshBuilder<P>

Create a new RingMeshBuilder<P> from a given Ring<P> shape.

pub fn with_inner( self, func: impl Fn(<P as Meshable>::Output) -> <P as Meshable>::Output, ) -> RingMeshBuilder<P>

Apply a function to the inner builders

Trait Implementations

impl<P> Extrudable for RingMeshBuilder<P>

where P: Primitive2d + Meshable, <P as Meshable>::Output: Extrudable,

fn perimeter(&self) -> Vec<PerimeterSegment>

A list of the indices each representing a part of the perimeter of the mesh.

Panics

Panics if the following assumptions are not met.

It is assumed that the inner and outer meshes have the same number of vertices. If not, then the MeshBuilder of the underlying 2d primitive has generated a different number of vertices for the inner and outer instances of the primitive.

It is assumed that the primitive_topology of the mesh returned by the underlying builder is PrimitiveTopology::TriangleList and that the mesh has Mesh::ATTRIBUTE_POSITION, Mesh::ATTRIBUTE_NORMAL and Mesh::ATTRIBUTE_UV_0 attributes.

where P: Primitive2d + Meshable,

fn build(&self) -> Mesh

Builds a Mesh based on the configuration in self.

Panics

Panics if the following assumptions are not met.

It is assumed that the inner and outer meshes have the same number of vertices. If not, then the MeshBuilder of the underlying 2d primitive has generated a different number of vertices for the inner and outer instances of the primitive.

It is assumed that the primitive_topology of the mesh returned by the underlying builder is PrimitiveTopology::TriangleList and that the mesh has Mesh::ATTRIBUTE_POSITION, Mesh::ATTRIBUTE_NORMAL and Mesh::ATTRIBUTE_UV_0 attributes.
