Class representing an axis aligned rectangular cuboid in 3D space. More...
Inheritance diagram for AlignedBox:Class representing an axis aligned rectangular cuboid in 3D space.
The coordinate convention for this class is bottom <= top, left <= right, front <= back, all of which are enforced in the constructor. Unless stated otherwise, all operations that involve comparisons use the same tolerance epsilon as vec3::isApprox() (which is 1e-12).
A default-constructed AlignedBox is considered "invalid" and represented by both lowerLeftFront() and upperRightBack() being NaN. Use isValid() to easily check for this.
Public Member Functions | |
| AlignedBox () | |
| Creates an invalid box that does not contain any point and does not intersect with anything. | |
| AlignedBox (const vec3 &point) | |
| Creates a box that consists of the single given point; it has zero extent but is valid. | |
| AlignedBox (const vec3 &lowerLeftFront, const vec3 &upperRightBack) | |
| Creates a box that spans the two given points. | |
| bool | operator== (const AlignedBox &) const |
| bool | operator!= (const AlignedBox &) const |
| bool | isApprox (const AlignedBox &) const |
| Floating point comparison using the same epsilon as Eigen::isApprox. | |
| void | addPoint (const vec3 &point) |
| Extends this box to include the given point. | |
| void | addBox (const AlignedBox &other) |
| Extends this box to include the other AlignedBox. | |
| void | reset () |
| Reset to an invalid bounding box. | |
| bool | isValid () const |
| Returns whether this box is valid (i.e. none of the LLF/URB components is NaN). | |
| bool | includesPoint (const vec3 &point) const |
| Returns whether the box contains the given point. | |
| vec3 | closestPoint (const vec3 &point) const |
Returns the point inside this box that is closest to point, NaN if isValid() is false. | |
| double | distanceToPoint (const vec3 &point) const |
Returns the distance of point to the closest point inside this box, NaN if isValid() is false. | |
| const vec3 & | lowerLeftFront () const |
| Returns the lower-left-front corner (component-wise minimum) of the bounding box. | |
| const vec3 & | upperRightBack () const |
| Returns the upper-right-back corner (component-wise maximum) of the bounding box. | |
| double | left () const |
| double | right () const |
| double | top () const |
| double | bottom () const |
| double | front () const |
| double | back () const |
| double | width () const |
| double | height () const |
| double | depth () const |
| vec3 | center () const |
| Returns the center of the bounding box. | |
| vec3 | extent () const |
| Returns the extent of the bounding box (URB - LLF). | |
| double | volume () const |
| Returns the volume of the bounding box. | |
| std::array< vec3, 8 > | corners () const |
| Returns corner in order left to right, bottom to top, front to back, i.e. | |

| std::array< vec3, 8 > corners | ( | ) | const |
Returns corner in order left to right, bottom to top, front to back, i.e.
with a x-major order.
