3D Box
|
inline |
Return true if the box is empty.

inline |
Return true if the Vector3 point is inside this box.
Referenced by DD::Image::rTriangle::intersect(), DD::Image::rTriangle::intersect_dist_squared(), and DD::Image::Scene::validate().
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.

void Box3::expand | ( | const Vector3 & | p | ) |
void Box3::transform | ( | const Matrix4 & | m | ) |
Transform each corner of the box by the matrix, merging them into a new axis-aligned box.

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