This method specifies the line properties

a_stippleFactor Specifies a multiplier for each bit in the line stipple pattern. If factor is 3, for example, each bit in the pattern is used three times before the next bit in the pattern is used. factor is clamped to the range [1, 256] and defaults to 1.

a_stipplePattern specifies a 16-bit integer whose bit pattern determines which fragments of a line will be drawn when the line is rasterized. Bit zero is used first; the default pattern is all 1's.

Parameters
a_stippleFactorLine stipple factor.
a_stipplePatternLine stipple pattern.

bool chai3d::cShapeLine::computeOtherCollisionDetection ( cVector3d a_segmentPointA,
cVector3d a_segmentPointB,
cCollisionRecorder a_recorder,
cCollisionSettings a_settings 
)
protectedvirtual

This method determines whether a given segment intersects this object.
The segment is described by a start point a_segmentPointA and end point a_segmentPointB.
All detected collisions are reported in the collision recorder passed by argument a_recorder.
Specifications about the type of collisions reported are specified by argument a_settings.

Parameters
a_segmentPointAStart point of segment.
a_segmentPointBEnd point of segment.
a_recorderRecorder which stores all collision events.
a_settingsCollision settings information.
Returns
true if a collision has occurred, false otherwise.

const bool  a_duplicateMaterialData,
const bool  a_duplicateTextureData,
const bool  a_duplicateMeshData,
const bool  a_buildCollisionDetector 
)
protected

This method copies all properties of this multi-mesh to another.

Parameters
a_objDestination object where properties are copied to.
a_duplicateMaterialDataIf true, material (if available) is duplicated, otherwise it is shared.
a_duplicateTextureDataIf true, texture data (if available) is duplicated, otherwise it is shared.
a_duplicateMeshDataIf true, mesh data (if available) is duplicated, otherwise it is shared.
a_buildCollisionDetectorIf true, collision detector (if available) is duplicated, otherwise it is shared.
void chai3d::cShapeLine::reset ( )
protected

Initialize line data.

void chai3d::cShapeLine::updateLinePoints ( )
protected

This method updates the position of line extremities according to if the line is attched to an object or simply efined in the local coordinate system of the line itself
