Struct de_pathing::segmentproj::SegmentOnSegmentProjection

pub(crate) struct SegmentOnSegmentProjection {
    side_a: Option<ParamPair>,
    middle: Option<ParamPair>,
    side_b: Option<ParamPair>,
}

Projection of a line segment onto another line segment from the perspective of an eye (a point). The projection can be looked at as a shadow cast by the one segment onto the other segment with the source of light placed at the eye.

Fields

side_a: Option<ParamPair>

middle: Option<ParamPair>

side_b: Option<ParamPair>

Implementations

impl SegmentOnSegmentProjection

pub(crate) fn construct( eye: Point<f32>, source: Segment, target: Segment ) -> Self

fn construct_a( ray_a_proj: RayProjection, ray_b_side: Side, target_length: f32 ) -> Option<ParamPair>

fn construct_b( ray_b_proj: RayProjection, ray_b_side: Side, target_length: f32 ) -> Option<ParamPair>

fn construct_middle( ray_a_proj: RayProjection, ray_b_proj: RayProjection, target_length: f32 ) -> Option<ParamPair>

fn new( side_a: Option<ParamPair>, middle: Option<ParamPair>, side_b: Option<ParamPair> ) -> Self

pub(crate) fn side_a(&self) -> Option<ParamPair>

Non-visible part of the target line segment adjacent to endpoint a. This is None when all of target is visible.

pub(crate) fn middle(&self) -> Option<ParamPair>

Visible part of the target line segment. This is None in None if no point of the target line segment is visible (from eye via the source line segment).

pub(crate) fn side_b(&self) -> Option<ParamPair>

Non-visible part of the target line segment adjacent to endpoint b. This is None when all of target is visible.
