Virtual natural phenomena

Abstract

This project investigates visual effects in motion pictures, with a focus on the following natural phenomena; fire, smoke and explosions. The aim is to obtain a clearer idea of what makes such phenomena look realistic. To understand this fully, the term ‘realistic’ is first defined. Furthermore, an in-depth study is done on fire dynamics, laws of physics and other features that affect its realism. This is then coupled with visual research from nature and related motion pictures to come up with a working understanding of such natural phenomena. Various techniques and software applications are then explored and compared to identify the best solution for the project. Several test experiments were done using the chosen software ‘Houdini’. These experiments were then combined with other visual material and shown in a focus group to acquire different views and opinions about the topic. The outcome of the research and focus group was of utmost importance to understand what is acceptable to the modern film audience. This gave significant insight to be able to produce further virtual natural phenomena for a short film that was produced to display the use of such effects. This process gives a clear understanding of how virtual natural phenomena can be used in a normal film production environment.
