Struct bevy::render::mesh::SphereMeshBuilder
pub struct SphereMeshBuilder {
pub sphere: Sphere,
pub kind: SphereKind,
}
Fields§
§sphere: Sphere
The Sphere
shape.
kind: SphereKind
The type of sphere mesh that will be built.
Implementations§
§impl SphereMeshBuilder
impl SphereMeshBuilder
pub const fn new(radius: f32, kind: SphereKind) -> SphereMeshBuilder
pub const fn new(radius: f32, kind: SphereKind) -> SphereMeshBuilder
Creates a new SphereMeshBuilder
from a radius and SphereKind
.
pub const fn kind(self, kind: SphereKind) -> SphereMeshBuilder
pub const fn kind(self, kind: SphereKind) -> SphereMeshBuilder
Sets the SphereKind
that will be used for building the mesh.
pub fn build(&self) -> Mesh
pub fn build(&self) -> Mesh
Builds a Mesh
according to the configuration in self
.
§Panics
Panics if the sphere is a SphereKind::Ico
with a subdivision count
that is greater than or equal to 80
because there will be too many vertices.

pub fn ico(&self, subdivisions: usize) -> Result<Mesh, IcosphereError>
pub fn ico(&self, subdivisions: usize) -> Result<Mesh, IcosphereError>
Creates an icosphere mesh with the given number of subdivisions.
The number of faces quadruples with each subdivision.
If there are 80
or more subdivisions, the vertex count will be too large,
and an IcosphereError
is returned.
A good default is 5
subdivisions.
