Bent Ray 3D Rendering for Depth Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3-D rendering techniques using ray tracing often fail to accurately preserve depth perception by treating light rays as straight lines, leading to the need for multiple passes to render foreground and background separately, which can result in inefficient processing and suboptimal image rendering.
Innovation Solution
The method employs bent rays, where the path of light is curved as a function of the distance from the camera, allowing for simultaneous rendering of all pixels in a view window by tracing paths that are progressively bent or curved, effectively simulating multiple camera perspectives and enhancing depth perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If straight rays are used for rendering, then the rendering process is simple, but depth perception is not accurately preserved
Solution Approach 1:
The patent applies curvature to light ray paths by introducing a bending function that curves rays based on their distance from the camera. This curvature allows rays to naturally diverge more at greater distances, accurately simulating perspective depth without requiring complex multi-pass rendering processes.
2Measurement precision
If multiple passes are used to render foreground and background separately, then depth perception is improved, but processing efficiency decreases
Solution Approach 1:
The patent merges the rendering of foreground and background into a single pass by using bent rays that naturally accommodate perspective depth. The bending function allows all pixels to be rendered simultaneously with correct depth relationships, eliminating the need for separate foreground and background rendering passes.
3Measurement precision
If bent rays are used for rendering, then depth perception is accurately preserved, but the rendering process becomes more complex
Solution Approach 1:
The patent changes the parameter of ray path from straight to curved by introducing a bending function that operates on ray distance from the camera. This parameter change enables accurate depth perception while maintaining computational efficiency through a unified single-pass rendering approach.
