Preview

Execution

After compiling the program with make, start the program with

./spline_plotter --spline_type {$spline_type} --show_convex_hull {$style} --CCont {} --GCont {}

Replace

• {$spline_type} with one of the following options {Hermite, Bezier, BSpline, CatmullRom, MINVO}
• {$style} with {0, 1, 2}
  • Selecting 1 will draw lines joining adjacent control points, 2 will draw the control polygons

Note the only required argument is --spline_type. The rest are optional.

Whilst running the program, click on the screen to insert control points.

Pressing,

• <F1> will clear all previously inserted points
• <r> will remove the last inserted point
• <e> will export the spline data in the results directory
