Bezier_Coons_Subdivision

Visualizer of mathematics algorithms in C++ and OpenGL

Features

Parametric curves

Bezier curves

Implementation of Bezier curve algorithm with step parameters.

• translation of any control points and regeneration of Bézier curve in realtime
• translation of Bezier curve in realtime

* Bezier curve extrusion in Z axis : compute a 3D mesh

* Bezier curve revolution : compute a 3D mesh

Chaikin curve

Implementation of Chaikin curve algorithm with u, v and iteration parameters.

• translation of any control points and regeneration of Chaikin curve in realtime

Coons surface

Implementation of coons surface from 4 chaikin curves. Can't translate nor change control points.

Mesh subdivision

Implementation of 3 meshes subdivisions algorithms iterations by iterations. All screenshots are the third iteration.
