Abstract: We present drawing on air, a haptic-aided input technique for drawing controlled 3D curves through space. Drawing on air addresses a control problem with current 3D modeling approaches based ...

Gradient Descent: This article describes how to implement a gradient descent using the differential approach (2D example implementation), then, using the perturbation approach (3D example ...

Routines to create rounded corners, with either circular rounding, or continuous curvature rounding with no sudden curvature transitions. Provides rounding of corners or rounding that preserves corner ...

What began with a focus on weather forecasting has evolved toward addressing errors in scientific modeling. In the collaborative environment of the Penn State Institute for Computational and Data ...
