# B-Spline Renderer 

Rendering 3D B-splines in ``C++`` using ``Qt``, ``OpenGL`` and ``Eigen``.

B-splines are parametric curves that consist of several Bézier curves whose control points satisfy specific conditions.

I used cubic Bézier curves for the interpolation of knots. Given a set of knots, 

a cubic Bézier curve is generated between each pair of knots. 

Then, these Bézier curves are glued together to form the final curve, the B-spline.

The algorithm for the generation of the curves can be found [here](https://www.math.ucla.edu/~baker/149.1.02w/handouts/dd_splines.pdf). Although it is about 2D B-splines, interpolating 3D B-splines is not so different.

## Build

1) Install `CMake 3.25.1` or above.

2) Install `Visual Studio 2022` and `MSVC C++ v143 Compiler`.

3) Install `Qt 6.7.3 MSVC2022 64bit` kit.

4) Set environment variable `Qt6_DIR` as `C:\Qt\6.7.3\msvc2022_64`.

5) Clone the repo `git clone https://github.com/berkbavas/BSplineRenderer.git`.

6) Create a folder `mkdir Build`.

7) Enter the folder `cd Build`.

8) Run CMake `cmake ..`.

9) Open `BSplineRenderer.sln` with `Visual Studio 2022`.

10) Build with `Release` configuration.
