| Summary: | Numerical analysis and computational simulation of partial differentialequation models in mathematical biology are now an integral partof the research in this field. Increasingly we are seeing the development ofpartial differential equation models in more than one space dimension, and itis therefore necessary to generate a clear and effective visualisation platformbetween the mathematicians and biologists to communicate the results. Themathematical extension of models to three spatial dimensions from one or twois often a trivial task, whereas the visualisation of the results is more complicated.The scope of this paper is to apply the established marching cubesvolume rendering technique to the study of solid tumour growth and invasion,and present an adaptation of the algorithm to speed up the surface renderingfrom numerical simulation data. As a specific example, in this paper we examinethe computational solutions arising from numerical simulation resultsof a mathematical model of malignant solid tumour growth and invasion in anirregular heterogeneous three-dimensional domain, i.e., the female breast. Dueto the different variables that interact with each other, more than one data setmay have to be displayed simultaneously, which can be realized through transparencyblending. The usefulness of the proposed method for visualisation ina more general context will also be discussed. |
