## Detailed Description

The **SbBox3i32** class is a 3 dimensional box with 32-bit integer coordinates.

This box class is used by other classes in Coin for data exchange. It provides storage for two box corners with 32-bit integer coordinates, which is among other things useful for representing screen or canvas areas in absolute window coordinates.

Check if the given point lies within the boundaries of this box.

### SbBool SbBox3i32::outside (const SbMatrix & mvp, int & cullbits) const

Check if the box is outside the view volume defined by the *mvp* matrix. Sets *cullbits* according to which planes we're inside or outside. Bit 0 (0x1) is cleared when box is completely inside left and right clipping planes. Bit 1 (0x2) is cleared when box is inside top and bottom clipping planes. Bit 2 (0x4) is cleared when box is inside near and far clipping planes.

Returns TRUE if box is completely outside one of the clipping planes. FALSE otherwise.

### SbVec3f SbBox3i32::getClosestPoint (const SbVec3f & point) const

**getMin()**.

### void SbBox3i32::getSize (int32\_t & sizeX, int32\_t & sizeY, int32\_t & sizeZ) const \[inline\]

Returns width, height and depth of box.

### SbVec3i32 SbBox3i32::getSize (void ) const \[inline\]

Returns width, height and depth of box as a 3D vector.

**Since**

Coin 3.0

### void SbBox3i32::getSpan (const SbVec3f & dir, float & dmin, float & dmax) const

Find the span of the box in the given direction (i.e. how much room in the given direction the box needs). The distance is returned as the minimum and maximum distance from origo to the closest and furthest plane defined by the direction vector and each of the box' corners. The difference between these values gives the span.
