| kzsError kzcReparametrizationCreateLinear | ( | const struct KzcMemoryManager * | memoryManager, |
| kzFloat | curveLength, | ||
| struct KzcReparametrization ** | out_reparametrization | ||
| ) |
Creates a linear curve length reparametrization by curve length.
| kzsError kzcReparametrizationCreateFromSpline | ( | const struct KzcMemoryManager * | memoryManager, |
| const struct KzcSpline * | spline, | ||
| kzUint | minimumSamples, | ||
| kzUint | maximumSubdivisions, | ||
| kzFloat | relativeErrorMagnitude, | ||
| struct KzcReparametrization ** | out_reparametrization | ||
| ) |
Creates a curve length reparametrization for a spline by sampling.
First splits the curve into secant lines by sampling at 'minimumSamples' points. After that subdivides the secants as long as the relative error estimate is over 'relativeErrorMagnitude' and 'maximumSubdivisions' depth is not reached.
| kzsError kzcReparametrizationDelete | ( | struct KzcReparametrization * | reparametrization | ) |
Deletes a reparametrization.
| kzFloat kzcReparametrizationGetPhaseParameter | ( | const struct KzcReparametrization * | reparametrization, |
| kzFloat | lengthParameter | ||
| ) |
Returns the phase that matches the given curve length in [0, length].
| kzFloat kzcReparametrizationGetLengthParameter | ( | const struct KzcReparametrization * | reparametrization, |
| kzFloat | phaseParamter | ||
| ) |
Returns the curve length that matches the given phase in [0, 1].
| kzFloat kzcReparametrizationGetCurveLength | ( | const struct KzcReparametrization * | reparametrization | ) |
Returns the curve length of the curve.
| kzUint kzcReparametrizationGetSampleCount | ( | const struct KzcReparametrization * | reparametrization | ) |
Returns number of sample points the reparametrization uses.
Can in some cases be used as an approximation for complexity of the curve.
| kzFloat kzcReparametrizationGetLengthSampleByIndex | ( | const struct KzcReparametrization * | reparametrization, |
| kzUint | index | ||
| ) |
Returns length parameter by index.
