Struct MeshParams 

pub struct MeshParams {
    pub coord_bits: u32,
    pub component_bits: u32,
    pub flag_bits: u32,
    pub components: usize,
    pub decode: Box<[f32]>,
    pub coord_max: u32,
    pub component_max: u32,
}

The bit widths and decode ranges a mesh stream declares.

Fields

coord_bits: u32

/BitsPerCoordinate.

component_bits: u32

/BitsPerComponent.

flag_bits: u32

/BitsPerFlag, unvalidated for the lattice type which has no flags.

components: usize

How many colour components each record carries — 1 whenever any function is present.

decode: Box<[f32]>

/Decode, [xmin, xmax, ymin, ymax, c0min, c0max, …].

coord_max: u32

2^coord_bits - 1.

component_max: u32

2^component_bits - 1.

Implementations

impl MeshParams

pub fn new( coord_bits: u32, component_bits: u32, flag_bits: u32, components: usize, decode: &[f32], kind: ShadingKind, ) -> Option<Self>

Validate the widths and the /Decode length.

kind decides whether /BitsPerFlag is validated at all: the lattice type reads no edge flags, so its value is never checked.

pub fn component_range(&self) -> [f32; 2]

The first colour component’s decode range — /Decode[4], /Decode[5].

Under a /Function this is the parametric value’s domain, which is what a ramp is sampled across. The length check in Self::new has already guaranteed both entries exist.
