Detailed Description

3D Box

Member Function Documentation

◆ empty()

bool DD::Image::Box3::empty ( ) const
inline

◆ inside()

bool DD::Image::Box3::inside ( const Vector3 p) const
inline

◆ expand() [1/2]

void Box3::expand ( const Box3 v)

Union the box with box v. If this is empty it is set to the other box, if the other one is empty this is unchanged.

References empty(), MAX(), and MIN().

Referenced by DD::Image::Render::_request(), DD::Image::Render::_validate(), DD::Image::Primitive::get_bbox(), transform(), DD::Image::Scene::validate(), and DD::Image::Iop::vertex_shader().

◆ expand() [2/2]

void Box3::expand ( const Vector3 p)

Expand the bbox to contain p. If it is empty it is set to a zero-size box at p.

References empty(), MAX(), and MIN().

◆ transform()

void Box3::transform ( const Matrix4 m)

Transform each corner of the box by the matrix, merging them into a new axis-aligned box.

References expand(), t(), and DD::Image::Matrix4::vtransform().

Referenced by DD::Image::GeoOp::add_draw_geometry(), DD::Image::GeoOp::build_scene(), DD::Image::ViewerContext::expand_bbox(), and DD::Image::Scene::validate().

◆ project()

void Box3::project ( const Matrix4 m,
Box bbox 
) const

Transform each corner of the box by a projection matrix, merging them into 2D bbox. This is typically used to project into screen space. Pass false to 'wnormalize' if the perspective division is not wanted.

References DD::Image::Box::set().

Referenced by DD::Image::Scene::validate().
