## Member Function Documentation

static float csSquaredDist::PointLine | ( | const csVector3 & | p,
|  | const csVector3 & | l1,
|  | const csVector3 & | l2 |
| ) |  |  | `[static]`

Returns the squared distance between a point and a line.

static float csSquaredDist::PointPlane | ( | const csVector3 & | p,
|  | const csPlane3 & | plane |
| ) |  |  | `[inline, static]`

Returns the squared distance between a point and a normalized plane.

Definition at line 243 of file math3d.h.

References csPlane3::Classify().

static float csSquaredDist::PointPoint | ( | const csVector3 & | p1,
|  | const csVector3 & | p2 |
| ) |  |  | `[inline, static]`

Returns the squared distance between two points.

Definition at line 232 of file math3d.h.

static float csSquaredDist::PointPoly | ( | const csVector3 & | p,
|  | csVector3 * | V,
|  | int | n,
|  | const csPlane3 & | plane,
|  | float | sqdist = `-1` |
| ) |  |  | `[static]`

Returns the squared distance between a point and a polygon.

If sqdist is >= 0, then it is used as the pre-calculated point to plane distance. V is an array of vertices, n is the number of vertices, and plane is the polygon plane.
