getClassType() → TypeHandle¶ - Return type
-
getNumPoints() → size_t¶ Returns the number of vertices of the CollisionPolygon.
- Return type
size_t
-
getPoint(n: size_t) → LPoint3¶ Returns the nth vertex of the CollisionPolygon, expressed in 3-D space.
- Return type
LPoint3
-
getPoints() → list¶
-
isConcave() → bool¶ Returns true if the CollisionPolygon appears to be concave, or false if it is safely convex.
-
isValid() → bool¶ Returns true if the CollisionPolygon is valid (that is, it has at least three vertices), or false otherwise.
-
property
points¶ Returns the nth vertex of the CollisionPolygon, expressed in 3-D space.
- Return type
Sequence[LPoint3]
-
property
valid¶ Returns true if the CollisionPolygon is valid (that is, it has at least three vertices), or false otherwise.
- Return type
bool

verifyPoints(a: LPoint3, b: LPoint3, c: LPoint3) → bool¶ Verifies that the indicated set of points will define a valid CollisionPolygon: that is, at least three non-collinear points, with no points repeated.
