Referenced by extendBy(), and transform().

void SbBox3i32::extendBy (const SbBox3i32

void SbBox3i32::makeEmpty (void)

Marks this as an empty box.

SbBool SbBox3i32::isEmpty (void) const [inline]

SbBool SbBox3i32::hasVolume (void) const [inline]

Check if the box has been correctly specified and by that virtue has volume.

float SbBox3i32::getVolume (void) const [inline]

Check if the box has 'positive' volume, i.e. the lower left corner is actually lower and more left than the maximum point.

SbBool SbBox3i32::intersect (const SbVec3i32

& pt) const

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

SbBool SbBox3i32::intersect (const SbBox3i32

& bb) const

Check if the given box

lies wholly or partly within the boundaries of this box.

SbBool SbBox3i32::intersect (const SbVec3f

& pt) const

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

 [inline]

Returns the center point of the box.

Referenced by getClosestPoint().

void SbBox3i32::getOrigin (int32_t & originX, int32_t & originY, int32_t & originZ) const [inline]

Returns the coordinates of the box origin (i.e. the lower left corner).

getMin(

)

void SbBox3i32::getSize (int32_t & sizeX, int32_t & sizeY, int32_t sizeZ) const [inline]

Returns width, height and depth of box.

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.
