A bounding box. Often used to encompass object's bounds in the world.
Can be used to check against a frustum and do culling.
| nkGraphics::BoundingBox::BoundingBox | ( | ) |
Default constructor.
| nkGraphics::BoundingBox::BoundingBox | ( | const nkMaths::Vector & | center, |
| float | cubeHalfSide | ||
| ) |
Constructor.
| center | The center of the box to create. |
| cubeHalfSide | The half extent, uniform along the 3 axis (x, y, z), used to form a cube. |
| nkGraphics::BoundingBox::BoundingBox | ( | const nkMaths::Vector & | center, |
| const nkMaths::Vector & | axisAlignedHalfSides | ||
| ) |
Constructor.
| center | The center of the box to create. |
| axisAlignedHalfSides | The half extents, for each axis. |
| nkGraphics::BoundingBox::~BoundingBox | ( | ) |
Destructor.

| void nkGraphics::BoundingBox::setPoints | ( | const std::array< nkMaths::Vector, 8 > & | points | ) |
Sets new points to use for the box.
| points | The points to use. |
| void nkGraphics::BoundingBox::updateTransformation | ( | Node * | node | ) |
Updates the transformed points with a node transformation.
| node | The node from which to retrieve the transformation. |
| bool nkGraphics::BoundingBox::checkAgainst | ( | const Frustum & | frustum | ) | const |
Checks the box against a frustum to know if it is inside or not.
| frustum | The frustum to check against. |
