- Description
- This dissertation sets out to find a pragmatic solution for optimizing both resolution and rendering issues in the context of contemporary environmental design computer modelling. In this regard the following issues are addressed: Firstly, determining (with reference to a limited selection of existing 3DS Max software and plugins (i.e. VRay and Mental-Ray), which specific piece of software produces the best compromise as far as visual accuracy is concerned whilst still offering the designer the best scope for further design manipulation. Secondly, establishing design techniques which can increase the speed of model making as well as reduce rendering time without having an adverse effect on issues such as resolution and image quality. Lastly, ascertaining the least number of surfaces for a typical geometrical shape (e.g. chair, table, ornament etc.) without losing visual veracity by manipulation of the design itself. The research strongly supports the notion that VRay is the best overall software to be employed as a base before applying any design solutions. In this latter regard a number of solutions became evident as a means to both save memory and cut down on rendering time, including such factors as using spotlight rather than an omni light when rendering, because omni light calculations include the generation of needless shadows. The beneficial effect of employing ‘target direct’ light and reducing the area of light in order to decrease the calculation of shadow. Eliminating objects which do not need shadows from the lighting calculation and shutting off the reverberation and refraction factors before rendering. It was also confirmed that a black and white mipmap is better than a colour mipmap as far as saving on the system’s memory.
