Abstract The report investigates computer generated (CG) lighting techniques with a focus on the rendering of interior architectural visualisations. With rapid advancements in CG technology, the demand and expectation for greater photorealism in visualisations are increasing. The tools to achieve this are widely available and fairly easy to apply; however, renderings on a local scale are still displaying functionality and lack visual appeal. The research discusses how design principles and aesthetics can be used effectively to create visual interest and display mood in the visualisation, with strong attention to the elements that are defined as the fundamentals in achieving photorealism. The focus is on a solid understanding of CG lighting techniques and principles in order to achieve high quality, dynamic visualisations. Case studies examine the work of lighting artist James Turrell and 3D artist Jose Pedro Costa and apply the findings to a creative project, encompassing the discussions in the report. The result is the completion of three photorealistic renderings of an interior visualisation, using different CG lighting techniques to convey mood. The research provides a platform for specialisation in the 3D environment and encourages a multidisciplinary approach to learning.
