Struct TessFactor 

pub struct TessFactor {
    pub n_u: u32,
    pub n_v: u32,
}

Tessellation factor (level of detail) for the compute mesher.

n_u angular steps around the surface and n_v steps along it. Higher values produce more triangles and a rounder silhouette at the cost of a larger vertex buffer; for a cylinder the chord error of the circular cross section falls off as 1 - cos(π / n_u).

Fields

n_u: u32

Angular subdivisions around the surface (clamped to [3, MAX_TESS]).

n_v: u32

Axial subdivisions along the surface (clamped to [1, MAX_TESS]).

Implementations

impl TessFactor

pub fn new(n_u: u32, n_v: u32) -> Self

Create a tessellation factor, clamping each dimension into the range that yields a non-degenerate closed mesh without overflowing the GPU buffer index math: n_u ∈ [3, MAX_TESS], n_v ∈ [1, MAX_TESS].
