Abstract
A scalar field is a generalisation of a surface function in dimension. Visualisation traditionally focuses on discrete specifications of scalar fields (e.g., volume datasets). This paper discusses the role of continuous and procedural field specifications in volume visualisation and volume graphics, and the inter-operations between continuous and discrete specifications. It demonstrates the different use of scalar fields through several modelling aspects, including constructive volume geometry and non-photorealistic textures, and presents our approaches to the creation of more photorealistic effects in direct volume rendering.
