Member Function Documentation

create_front_back()

std::pair< Vec3d, Vec3d > Emboss::OrthoProject::create_front_back ( const Point & p ) const

overridevirtual

convert 2d point to 3d points

Parameters

p	2d coordinate

Returns

first - front spatial point second - back spatial point

Implements Slic3r::Emboss::IProjection.

                                                                                {
    Vec3d front(p.x(), p.y(), 0.);
    Vec3d front_tr = m_matrix * front;
    return std::make_pair(front_tr, project(front_tr));
}

Move point with respect to projection direction e.g. Orthogonal projection will move with point by direction e.g. Spherical projection need to use center of projection.

Parameters

point

Spatial point coordinate

Returns

Projected spatial point

Implements Slic3r::Emboss::IProject3d.

unproject()

std::optional< Vec2d > Emboss::OrthoProject::unproject ( const Vec3d & p, double * depth = nullptr ) const

overridevirtual

Back projection.

Parameters

p	Point to project
depth	[optional] Depth of 2d projected point. Be careful number is in 2d scale

Returns

Uprojected point when it is possible

Implements Slic3r::Emboss::IProjection.

    Vec3d pp = m_matrix_inv * p;
    if (depth != nullptr) *depth = pp.z();
    return Vec2d(pp.x(), pp.y());
