Multi-Process Compositor Unified 3D Lighting Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional compositors are unable to realistically render 3D content by allowing shadows and light to affect other content in a unified lighting environment, as they only handle 2D representations and lack proper occlusion in 3D space.
Innovation Solution
A multi-process compositor that uses a physically based renderer to combine 2D and 3D content within a global scene graph, enabling realistic rendering of shadows, light emission, and light reflection across processes, with secure communication channels for resource sharing and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional compositor is used to combine content from multiple processes, then the compositing function is achieved, but realistic 3D rendering with unified lighting and shadow effects cannot be realized
Solution Approach 1:
The system segments the compositing function into multiple independent processes that each render their own 3D content with proper lighting and shadows. Instead of one compositor handling all content, multiple processes work independently and their rendered outputs are composited together, enabling realistic 3D effects while maintaining modular architecture.
Solution Approach 2:
The patent introduces an intermediary compositing layer that receives pre-rendered content from multiple processes and combines them with unified lighting and shadow effects. This intermediary layer acts as a mediator between independent rendering processes, enabling realistic 3D compositing without requiring each process to handle all lighting calculations.
2Reliability
If 3D content from multiple processes is rendered in a unified lighting environment, then realistic light and shadow interactions are achieved, but the system complexity and communication overhead increase
Solution Approach 1:
Each process performs preliminary rendering of its 3D content with local lighting and shadow calculations before compositing. By pre-rendering content with accurate lighting effects in each process, the system avoids the complexity of real-time inter-process lighting calculations while maintaining realistic visual effects in the final composite.
Solution Approach 2:
The system uses copying of rendered content between processes through secure communication channels. Each process creates a copy of its rendered 3D content and shares it with the compositing layer, avoiding the need for complex real-time coordination and reducing communication overhead while maintaining rendering accuracy.
3Reliability
If secure communication channels are implemented between discrete processes for resource sharing, then process security is maintained, but communication overhead and system complexity increase
Solution Approach 1:
The patent extracts security verification into a separate mechanism that operates independently from the main communication flow. By taking out security checks and performing them asynchronously or in batch, the system maintains process security while reducing the time overhead of synchronous security verification during resource sharing operations.

AI summary
This technology relates to rendering content from discrete applications. In this regard, one or more computing devices may receive a global scene graph containing resources provided by two or more discrete processes, wherein the global scene graph is instantiated by a first process of the two or more discrete processes. The one or more computing devices may render and output for display, the global scene graph in accordance with the resources contained there.
