Struct ChunkMapSource 

pub struct ChunkMapSource<S> { /* private fields */ }

Bounded source adapter for chunk-local crop and affine transform operations.

Implementations

impl<S: BoundedSpatialRecordSource> ChunkMapSource<S>

pub fn crop( source: S, min: [f32; 3], max: [f32; 3], invert: bool, ) -> RecordsResult<Self>

Creates a crop adapter and validates ordered finite bounds.

pub fn transform(source: S, transform: Mat4<f32>) -> RecordsResult<Self>

Creates an affine transform adapter.

pub fn into_inner(self) -> S

Consumes the adapter and returns the upstream source.
