Real-Time Rendering: Computer Graphics with Control Engineering (Hardcover)

Consumers today expect extremely realistic imagery generated in real time for interactive applications such as computer games, virtual prototyping, and scientific visualisation. However, the increasing demands for fidelity coupled with rapid advances in hardware architecture pose a challenge: how do you find optimal, sustainable solutions to accommodate both speed of rendering and quality? Real-Time Rendering: Computer Graphics with Control Engineering presents a novel framework for solving the perennial challenge of resource allocation and the trade-off between quality and speed in interactive computer graphics rendering.

Conventional approaches are mainly based on heuristics and algorithms, are largely application specific, and offer fluctuating performance, particularly as applications become more complex. The solution proposed by the authors draws on powerful concepts from control engineering to address these shortcomings. Expanding the horizon of real-time rendering techniques, this book:

• Explains how control systems work with real-time computer graphics
• Proposes a data-driven modelling approach that more accurately represents the system behaviour of the rendering process
• Develops a control system strategy for linear and non-linear models using proportional, integral, derivative (PID) and fuzzy control techniques
• Uses real-world data from rendering applications in proof-of-concept experiments
• Compares the proposed solution to existing techniques
• Provides practical details on implementation, including references to tools and source code

This pioneering work takes a major step forward by applying control theory in the context of a computer graphics system. Promoting cross-disciplinary research, it offers guidance for anyone who wants to develop more advanced solutions for real-time computer graphics rendering.

現今的消費者對於互動應用程式（如電腦遊戲、虛擬原型和科學視覺化）期望能夠提供極為逼真的即時圖像。然而，對於畫質的要求不斷提高，並且硬體架構的快速進步也帶來了一個挑戰：如何找到既能保證渲染速度又能提供高品質的最佳解決方案？

《Real-Time Rendering: Computer Graphics with Control Engineering》提出了一個新穎的框架，用於解決互動式電腦圖形渲染中資源分配和品質與速度之間的權衡問題。傳統方法主要基於經驗法則和算法，往往具有特定應用的局限性，並且在應用變得更加複雜時性能會波動不定。本書提出的解決方案借鑒了控制工程的強大概念來解決這些問題。本書擴展了實時渲染技術的範疇，具體內容如下：

- 解釋了控制系統如何與實時電腦圖形工作
- 提出了一種基於數據驅動的建模方法，更準確地表示渲染過程的系統行為
- 運用比例、積分、微分（PID）和模糊控制技術，為線性和非線性模型開發了控制系統策略
- 使用渲染應用的真實數據進行概念驗證實驗
- 將所提出的解決方案與現有技術進行比較
- 提供實施的實用細節，包括工具和源代碼的參考

這項開創性的工作在計算機圖形系統的背景下應用了控制理論，是向前邁出的重要一步。它促進了跨學科研究，為希望開發更高級實時電腦圖形渲染解決方案的任何人提供了指導。
