Solution Overview

Problem

Current Web-side rendering technologies face challenges in achieving realistic and high-quality global illumination effects due to the limitations of rasterization rendering and the high computational cost of ray tracing, making it difficult to apply realistic rendering methods in real-time on the Web.

Innovation Solution

A Web-side real-time hybrid rendering method that combines rasterization rendering for parts with slow convergence speed and low-frequency results with ray tracing for parts with fast convergence speed and high-frequency results, and mixes the rendering results of the current and historical frames to enhance realism and reduce computational overhead.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If ray tracing rendering is used to achieve realistic global illumination effects, then rendering realism is improved, but computational cost increases significantly

Engineering Contradiction:
Improverendering realismVSAvoidcomputational cost
Core Design Contradiction:
Manufacturing precisionVSUse of energy by stationary object

Solution Approach 1:

The patent segments the rendering process into two distinct parts: ray tracing rendering for global illumination effects and rasterization rendering for other visual elements. This segmentation allows each rendering method to be applied only where it is most effective, reducing overall computational cost while maintaining rendering realism in critical areas

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different rendering qualities to different parts of the scene by using ray tracing specifically for global illumination effects where high realism is needed, while using rasterization for other areas. This local quality approach optimizes computational resources by concentrating high-quality rendering only where it provides the most visual benefit

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If ray tracing is applied for real-time rendering, then rendering quality is improved, but rendering speed decreases due to high computational requirements

Engineering Contradiction:
Improverendering qualityVSAvoidrendering speed
Core Design Contradiction:

Solution Approach 1:

The patent divides the rendering workload into ray tracing rendering for global illumination and rasterization rendering for other elements, allowing parallel processing and optimization of each component's speed contribution to the overall rendering pipeline

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies ray tracing rendering partially, only for specific global illumination effects rather than the entire scene, thereby achieving improved rendering quality in critical areas while maintaining acceptable overall rendering speed

Inventive Principle:
Principle #16Partial or excessive action

3Use of energy by stationary object

If rasterization rendering is used on the Web-side, then computational overhead is reduced, but global illumination effects and realism are insufficient

Engineering Contradiction:

Solution Approach 1:

The patent enhances rasterization rendering by locally applying ray tracing rendering specifically for global illumination effects, thereby maintaining low computational overhead for the overall system while improving global illumination quality in specific areas where it matters most

Inventive Principle:
Principle #3Local quality
