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.
|
inline |
The default constructor makes an empty box.
|
inline |
Constructs a box with the given corners.
xmin should be less than xmax, ymin should be less than ymax and zmin should be less than zmax if you want to make a valid box.
Constructs a box with the given corners.
The coordinates of minpoint should be less than the coordinates of maxpoint if you want to make a valid box.

Reset the boundaries of the box.
xmin should be less than xmax, ymin should be less than ymax and zmin should be less than zmax if you want to make a valid box.
Returns reference to self.
Reset the boundaries of the box with the given corners.
The coordinates of minpoint should be less than the coordinates of maxpoint if you want to make a valid box.
Returns reference to self.
Reset the boundaries to the boundaries of the given box.
Returns reference to self.
Reset the boundaries to the boundaries of the given box.
Returns reference to self.
Reset the boundaries to the boundaries of the given box.
Returns reference to self.
|
inline |
Returns the box boundaries.
Returns the box corner points.
|
inline |
Returns the minimum point. This should usually be the lower left corner point of the box.
|
inline |
Returns a modifiable reference to the minimum point.
|
inline |
Returns the maximum point. This should usually be the upper right corner point of the box.
|
inline |
Returns a modifiable reference to the maximum point.
void SbBox3i32::extendBy | ( | const SbVec3i32 & | point | ) |
Extend the boundaries of the box by the given point, i.e. make the point fit inside the box if it isn't already within it.
void SbBox3i32::extendBy | ( | const SbBox3i32 & | box | ) |
Extend the boundaries of the box by the given box parameter. This is equal to calling extendBy() twice with the corner points.
void SbBox3i32::extendBy | ( | const SbVec3f & | point | ) |
Extend the boundaries of the box by the given point, i.e. make the point fit inside the box if it isn't already within it.
void SbBox3i32::transform | ( | const SbMatrix & | matrix | ) |
Transform the box by the matrix, and change its boundaries to contain the transformed box.
Doesn't touch illegal/empty boxes.
void SbBox3i32::makeEmpty | ( | void | ) |
Marks this as an empty box.
|
inline |
Check if this has been marked as an empty box.
|
inline |
Check if the box has been correctly specified and by that virtue has "positive" volume, i.e. all coordinates of its upper right corner (the maximum point) are greater than the corresponding coordinates of its lower left corner (the minimum point).
|
inline |
Returns the volume of the box.
Check if the given point lies within the boundaries of this box.
Check if box lies entirely or partially within the boundaries of this box.
Check if the given point lies within the boundaries of this box.
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.
Return the point on the box closest to the given point. If the given point equals the center, the center point of the positive Z face is returned.
|
inline |
Returns the center point of the box.
|
inline |
Returns the coordinates of the box origin (i.e. the lower left corner).
|
inline |
Returns width, height and depth of box.
|
inline |
Returns width, height and depth of box as a 3D vector.
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.
Check b1 and b2 for inequality.
