Struct DecimateOptions 

pub struct DecimateOptions {
    pub target_faces: usize,
    pub max_error: Option<f64>,
}

Options controlling how far decimation proceeds.

Decimation stops as soon as either limit is reached:

• target_faces: stop once the live triangle count is <= target_faces.
• max_error: stop once the cheapest available collapse would exceed this quadric error. None means “no error ceiling” (run to target_faces).

At least one of the two must bound the run; if both are None, decimation runs until no further legal collapse exists (full simplification), which is well-defined but rarely what a caller wants — prefer setting a target.

Fields

target_faces: usize

Target live triangle count. Collapsing stops at or below this.

max_error: Option<f64>

Optional quadric-error ceiling; collapses costing more are not taken.

Implementations

impl DecimateOptions

pub const fn to_faces(target_faces: usize) -> Self

Decimate down to target_faces with no explicit error ceiling.

pub const fn to_error(max_error: f64) -> Self

Decimate greedily until the cheapest collapse would exceed max_error (with a target_faces floor of 0 — i.e. error is the only stop).

Trait Implementations

impl Clone for DecimateOptions

fn clone(&self) -> DecimateOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DecimateOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for DecimateOptions

fn eq(&self, other: &DecimateOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
