# cpp-spline
Package provides C++ implementation of spline interpolation
# Features
* Bezier Curve
* B-Spline
* CatmullRom
# Usage
# Bezier
To create a Bezier Curve in 2D or 3D environment:
```cpp
#include
#include "../../main/cpp/Bezier.h"
int main(char** argv, int argc) {
Curve* curve = new Bezier();
curve->set_steps(100); // generate 100 interpolate points between the last 4 way points
curve->add_way_point(Vector(1, 1, 0));
curve->add_way_point(Vector(2, 3, 0));
curve->add_way_point(Vector(3, 2, 0));
curve->add_way_point(Vector(4, 6, 0));
...
std::cout << "nodes: " << curve->node_count() << std::endl;
std::cout << "total length: " << curve->total_length() << std::endl;
for (int i = 0; i < curve->node_count(); ++i) {
std::cout << "node #" << i << ": " << curve->node(i).toString() << " (length so far: " << curve->length_from_starting_point(i) << ")" << std::endl;
}
delete curve;
}
```
# BSpline
To create a BSpline Curve in 2D or 3D environment:
```cpp
#include
#include "../../main/cpp/BSpline.h"
int main(char** argv, int argc) {
Curve* curve = new BSpline();
curve->set_steps(100); // generate 100 interpolate points between the last 4 way points
curve->add_way_point(Vector(1, 1, 0));
curve->add_way_point(Vector(2, 3, 0));
curve->add_way_point(Vector(3, 2, 0));
curve->add_way_point(Vector(4, 6, 0));
...
std::cout << "nodes: " << curve->node_count() << std::endl;
std::cout << "total length: " << curve->total_length() << std::endl;
for (int i = 0; i < curve->node_count(); ++i) {
std::cout << "node #" << i << ": " << curve->node(i).toString() << " (length so far: " << curve->length_from_starting_point(i) << ")" << std::endl;
}
delete curve;
}
```
# CatmullRom
To create a CatmullRom Curve in 2D or 3D environment:
```cpp
#include
#include "../../main/cpp/CatmullRom.h"
int main(char** argv, int argc) {
Curve* curve = new CatmullRom();
curve->set_steps(100); // generate 100 interpolate points between the last 4 way points
curve->add_way_point(Vector(1, 1, 0));
curve->add_way_point(Vector(2, 3, 0));
curve->add_way_point(Vector(3, 2, 0));
curve->add_way_point(Vector(4, 6, 0));
...
std::cout << "nodes: " << curve->node_count() << std::endl;
std::cout << "total length: " << curve->total_length() << std::endl;
for (int i = 0; i < curve->node_count(); ++i) {
std::cout << "node #" << i << ": " << curve->node(i).toString() << " (length so far: " << curve->length_from_starting_point(i) << ")" << std::endl;
}
delete curve;
}
```
