Bspline Basis Function Visualization

A project to visualize B-Spline basis functions to check their validity.

Setting

• Basis Function Order: configure in run.sh
• Knots Vector: define in gen_knots.py
• X-Axis Label: set in pgfplots/pgfplots.tex
• Plot Files: Adjust in pgfplots/pgfplots.tex

Notes

• make_splines.py is currently not published.

Run

./src/run.sh

Examples

Summary: Knot Invertion

Example 1: B-Spline Basis Function (Second Order) knots vector: [0,0,0,1,2,3,4,4,4]

Example 2: B-Spline Basis Function (Third Order)

knots vector: [0,0,0,0,1,2,3,4,4,4,4]
