Types¶
Vec3 (struct)¶
The Vec3 type represents a vector with 3 components. The Vec3 is also used as the row type for the Mat33.
注釈
Vec3 utilizes the KL ベクタ関数

Functions¶
closestPointToLineRatio¶
Scalar closestPointToLineRatio ( in Vec3 P, in Vec3 lineP0, in Vec3 lineP1 )
Returns the line ratio for the closest line location from point P
distFromPointToLine¶
Scalar distFromPointToLine ( in Vec3 P, in Vec3 lineP0, in Vec3 lineP1 )
Returns the distance of this vector to a line defined by two points on the line
closestSegmentPoint¶
Vec3 closestSegmentPoint ( in Vec3 P, in Vec3 segmentP0, in Vec3 segmentP1, out Scalar ratio )
Returns the closest point this position to a line segment defined by the start and end points
distFromPointToSegment¶
Scalar distFromPointToSegment ( in Vec3 P, in Vec3 segmentP0, in Vec3 segmentP1 )
Returns the distance of this position to a line segment defined by the start and end points
distanceFromLineToLine¶
Float64 distanceFromLineToLine ( in Vec2_d l1_p0, in Vec2_d l1_p1, in Vec2_d l2_p0, in Vec2_d l2_p1, out Float64 l1_t, out Float64 l2_t )
dist3D_Line_to_Line(): Input: two 3D lines L1 and L2 Return: the shortest distance between L1 and L2
testCoplanarity¶
Boolean testCoplanarity ( in Vec3 x1, in Vec3 x2, in Vec3 x3, in Vec3 x4, in Vec3 v1, in Vec3 v2, in Vec3 v3, in Vec3 v4, out Scalar outFraction )
Coplanarity test for 4 moving points. These moving points could either be a point and a triangle, or 2 edges. The returned fraction tells us if they will be coplanar within the next time step. This algorithm is used to compute continuous collision between points and triangle, or between moving lines. Algorithm based on the following paper. http://wscg.zcu.cz/wscg2007/Papers_2007/journal/D11-full.pdf
| x1 | The first points position |
| x2 | The second points position |
| x3 | The third points position |
| x4 | The fourth points position |
| v1 | The first points displacement over a the given time step |
| v2 | The second points displacement over a the given time step |
| v3 | The third points displacement over a the given time step |
| v4 | The fourth points displacement over a the given time step |
| outFraction | The return value containing the fraction of the timestep where all 4 points became coplanar. |
