Inertial Particles and Integral Curves

Image


I put together a few lines of code that explain the modeling of inertial particles and the computation of inertial integral curves.
Code and explanations can be found here: Inertial Particles and Integral Curves

Monte Carlo Rendering of FTLE

Image


We wrote a small reference implementation that uses unbiased freepath sampling to render Finite-time Lyapunov exponents.
A CPU implementation (cross-platform) and GPU implementation (windows only) can be found on GitHub. See Small MCFTLE for more details.

Caustic Blending

A Matlab implementation of the caustic blending in the Stylized Caustics paper is now available on GitHub.

Decoupled Opacity Optimization

Image



A Direct3D demo for line data of our Decoupled Opacity Optimization paper is now available on GitHub (including three line data sets).

Generic Objective Vortices for Flow Visualization

A VTK filter for our objective local reference frames from the paper Generic Objective Vortices for Flow Visualization is available on GitHub for unsteady 2D vector fields.

Hyper Objective Vortices

Image


A VTK filter for our affine-invariant local reference frames from the paper Hyper Objective Vortices is available on GitHub for unsteady 2D vector fields.

Stylized Image Triangulation

Image


A Direct3D implementation of our iterative image triangulation algorithm of the paper Stylized Image Triangulation is available on GitHub for the most basic rendering styles.

Displacement Optimization of Reference Frames in Unsteady Flow

A VTK filter for our displacement optimization of local reference frames from the paper Vector Field Topology of Time-Dependent Flows in a Steady Reference Frame is available on GitHub for unsteady 2D vector fields.
