Nondissipative Marbling

IEEE Computer Graphics and Applications, 2008
A real-time marbling system for creating marbling textures interactively uses a modern GPU. The approach models the marbling texture design process as a 2D fluid-dynamics problem and forms textures as a result of the color advection in the 2D flow fields.

Mathematical Marbling

IEEE Computer Graphics and Applications, 2012
In this paper, the proposed method takes a mathematical approach with closed-form expressions to simulate marbling. This method improves control, ease of implementation, parallelism, and speed, enabling real-time visual feedback and creation of vivid flowing animations. Users can start designs from a blank sheet, raster images, or videos.

Liquid marbles

Nature, 2001
The transport of a small amount of liquid on a solid is not a simple process, owing to the nature of the contact between the two phases. Setting a liquid droplet in motion requires non-negligible forces (because the contact-angle hysteresis generates a force opposing the motion), and often results in the deposition of liquid behind the drop.

Lighting marble

Proceedings of the 45th annual southeast regional conference, 2007
A method is suggested for modeling subsurface light transport through highly scattering materials such as marble. The technique is a natural extension of previous work describing the use of a lattice-Boltzmann method for calculating light transport in clouds and other participating media.

Metropolitan marble technology and marble workshops

2022
Abstract Chapter 9 outlines the increasingly sophisticated metropolitan marble-working techniques in the Antonine period, that were employed to enhance the effect of the portraits and keep up with the latest hair- and beard-styles. Portrait models, their ‘replication’, and adjustment are briefly discussed.
