A progressive refinement approach for the visualisation of implicit surfaces [PDF]

, 2007
Visualising implicit surfaces with the ray casting method is a slow procedure. The design cycle of a new implicit surface is, therefore, fraught with long latency times as a user must wait for the surface to be rendered before being able to decide what ...

Investigation of a Tetrathiafulvalene-Based Fe²⁺ Thermal Spin Crossover Assembled on Gold Surface

Magnetochemistry, 2022
A thick film and a monolayer of tetrathiafulvalene-based Fe2+ spin-crossover complex have been deposited by solution on a Au (111) substrate, attempting both self-assembling monolayer protocol and a simpler drop-casting procedure.

Interactive Ray Casting of Geodesic Grids [PDF]

Computer Graphics Forum, 2013
AbstractGeodesic grids are commonly used to model the surface of a sphere and are widely applied in numerical simulations of geoscience applications. These applications range from biodiversity, to climate change and to ocean circulation. Direct volume rendering of scalar fields defined on a geodesic grid facilitates scientists in visually understanding
