template<typename T>
struct tgx::Box3< T >
Generic 3D Box [specializations iBox3, fBox3, dBox3].
The class encapsulates of 6 public variables: minX
, maxX
, minY
, maxY
, minZ
, maxZ
which delimit the 3 dimensional closed box: [minX, maxX] x [minY, maxY] x [minZ, maxZ]
The box is empty if maxX
< minX
or if maxY
< minY
or if maxZ
< minZ
.
- Warning
- Some methods compute things differently depending whether T is an integral or a floating point value type.
- Template Parameters
-
T | arithmetic type of the box (int , float ...) |
