Trait ncollide::query::RichPointQuery

pub trait RichPointQuery<P, M> where
    P: Point, {
    type ExtraInfo;
    fn project_point_with_extra_info(
        &self, 
        m: &M, 
        pt: &P, 
        solid: bool
    ) -> (PointProjection<P>, Self::ExtraInfo);
}

Returns shape-specific info in addition to generic projection information

One requirement for the PointQuery trait is to be usable as a trait object. Unfortunately this precludes us from adding an associated type to it that might allow us to return shape-specific information in addition to the general information provided in PointProjection. This is where RichPointQuery comes in. It forgoes the ability to be used as a trait object in exchange for being able to provide shape-specific projection information.

Any shapes that implement PointQuery but are able to provide extra information, can implement RichPointQuery in addition and have their PointQuery::project_point implementation just call out to RichPointQuery::project_point_with_extra_info.

Associated Types

type ExtraInfo

Additional shape-specific projection information

In addition to the generic projection information returned in PointProjection, implementations might provide shape-specific projection info. The type of this shape-specific information is defined by this associated type.

Required Methods

fn project_point_with_extra_info(
    &self,
    m: &M,
    pt: &P,
    solid: bool
) -> (PointProjection<P>, Self::ExtraInfo)

Projects a point on self transformed by m.
