pub struct ClipPlane(/* private fields */);

Implementations

impl ClipPlane

pub fn signed_dist(&self, pt: &ClipVec) -> f32

Returns the signed distance between pt and self.

The return value is positive if pt is “outside” the plane, defined as the half-space in the direction of the normal vector, negative if pt is in the other half-space, and zero if pt is exactly coincident with the plane:

           n
           ^       d > 0
           |         x
           |         |
           |_        |
-----x-----+-'------------ self
   d = 0         |
                 x
               d < 0

pub fn outcode(&self, pt: &ClipVec) -> u8

Computes this plane’s outcode bit for a point.

The result is self.1 if pt is outside this plane, 0 otherwise.

pub fn is_inside<A>(&self, v: &ClipVert<A>) -> bool

Checks the outcode of a clip vertex against self.

Returns true if this plane’s outcode bit in v is 0, false otherwise.

pub fn intersect<A: Lerp>( &self, [v0, v1]: [&ClipVert<A>; 2], ) -> Option<ClipVert<A>>

pub fn clip_simple_polygon<A: Lerp + Clone>( &self, verts_in: &[ClipVert<A>], verts_out: &mut Vec<ClipVert<A>>, )

Clips a convex polygon against self.

Returns the resulting vertices in the out parameter verts_out.

In the diagram below, clipping triangle ABC results in quad ABPQ, where P and Q are new vertices generated by interpolating between A and C, and B and C, respectively.
