Struct CircularSegmentMeshBuilder

pub struct CircularSegmentMeshBuilder {
    pub segment: CircularSegment,
    pub resolution: u32,
    pub uv_mode: CircularMeshUvMode,

Fields

segment: CircularSegment

The segment shape.

resolution: u32

The number of vertices used for the arc portion of the segment mesh. The default is 32.

uv_mode: CircularMeshUvMode

The UV mapping mode

Implementations
