Public Types | |
|
typedef std::vector < Nimble::Vector2f > | container |
| Container for points on path. | |
Public Member Functions | |
| void | addPoint (Nimble::Vector2f p) |
| Adds a point to the end of the path. | |
| Nimble::Vector2f | center () const |
| Returns the center of the path computed from the point average. | |
| void | clear () |
| Clears all points. | |
| bool | isDegenerate () const |
| Returns true if the path only contains two points that are very close to each other. | |
| Nimble::Vector2f | point (size_t i) const |
| Returns the ith point on the path. | |
| container | points () |
| Returns the points that make up the path. | |
| void | simplify (float clusterTolerance, float dpTolerance) |
| Simplifies the path using a two-pass algorithm. More... | |
| void | simplifyAngular (float degrees) |
Simplifies the path by removing points based on the angle each segment differs from the previous segment. More... | |
| size_t | size () const |
| Returns the number of points on the path. | |
| void | transform (const Nimble::Matrix3f &m) |
| Transforms the points on the path with the given matrix. | |
Static Public Member Functions | |
| static bool | intersect (const Path &p1, const Nimble::Matrix3f &m1, const Path &p2, const Nimble::Matrix3f &m2) |
| Tests whether two transformed paths intersect. | |

| void Nimble::Path::simplify | ( | float | clusterTolerance, |
| float | dpTolerance | ||
| ) |
Simplifies the path using a two-pass algorithm.
First, clustered points are merged together and after this a second pass simplification is performed using the Douglas-Plucker method.
| clusterTolerance | points within this distance from eachother are merged together |
| dpTolerance | tolerance for Douglas-Plucker method |
| void Nimble::Path::simplifyAngular | ( | float | degrees | ) |
Simplifies the path by removing points based on the angle each
segment differs from the previous segment.
Each segment that forms an angle less than the given tolerance from the previous segment is removed.
| degrees | angle tolerance |
