Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The computation of indirect lighting in computer games and three-dimensional interactive programs is too expensive for computationally less powerful devices like phones and tablets, making it difficult for them to render scenes with high-quality graphics.
Innovation Solution
A system and method for computing indirect lighting in a cloud network using voxel-based, photon-based, or irradiance-map-based algorithms, where computations are performed on a cloud network and the results are streamed to client devices for rendering, allowing for efficient use of resources and improved graphics quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If indirect lighting computation is performed on client devices, then rendering quality is improved, but device power consumption increases and computational feasibility decreases
Solution Approach 1:
The rendering computation is segmented into two parts: direct lighting is computed on the client device while indirect lighting is computed on remote server systems. This segmentation allows the computationally expensive indirect lighting calculation to be performed elsewhere, reducing the power consumption and computational burden on mobile devices while maintaining high rendering quality.
2Measurement precision
If indirect lighting computation is performed on client devices, then rendering quality is improved, but device complexity requirements increase
Solution Approach 1:
The indirect lighting computation function is extracted from the client device and transferred to remote server systems. This extraction removes the complex computational requirements from mobile devices, allowing them to render high-quality graphics without requiring powerful local processing capabilities.
3Use of energy by moving object
If indirect lighting is not computed, then device power consumption remains low, but rendering quality deteriorates
Solution Approach 1:
A network communication system acts as an intermediary between the client device and the remote server. The server computes indirect lighting and transmits the results to the client, enabling high rendering quality without requiring the client device to perform the computationally expensive calculations locally.
