Now game developers must be more concerned about feeding the 3D accelerator enough data to keep it busy. Computing 3D geometry is a fairly straightforward task. It simply requires spitting out processed vertices as fast as possible to keep the accelerator well fed. By nature, custom 3D pipelines can take advantage of known, a priori characteristics of 3D content that a general engine cannot always exploit. Data structures can be optimized.
Optimized structures increase performance.
Custom lighting can be used, which often looks better a standard API s lighting support. This results in better visual quality. The bottom line is that when performance and quality are a high priority, the motivation for using a custom engine is greater. All rights reserved.
