Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current simulators lack the capability to generate realistic three-dimensional cockpit views with dynamic shadowing and reflections, resulting in a less immersive training experience due to the high processing power required for rendering hundreds of flight instruments and controls in real-time.
Innovation Solution
A simulation system that uses a computing device with a graphics processing unit (GPU) to maintain a cockpit model and generate shared cockpit scene information, determining cockpit view frustums for each frame to produce multiple three-dimensional cockpit views with realistic shadowing and reflections, reducing processing load by updating only the necessary cockpit model parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If realistic 3D cockpit views with dynamic shadowing and reflections are generated, then the immersion and realism of the training experience is improved, but the processing power required increases significantly
Solution Approach 1:
The rendering process is divided into multiple passes: a first pass generates a preliminary image with basic lighting, and a second pass adds dynamic shadowing and reflections. This segmentation allows the system to build realism incrementally without requiring all processing power at once, resolving the contradiction between achieving photorealistic quality and managing computational resources.
Solution Approach 2:
The system pre-calculates and stores lighting information, shadow maps, and reflection data during the first rendering pass before generating the final image. By performing preliminary actions to prepare lighting and shadow data in advance, the second pass can efficiently add realistic effects without excessive processing demands during real-time operation.
2Adaptability or versatility
If multiple cockpit views are rendered simultaneously, then the comprehensiveness of the simulation is improved, but the rendering time and processing load increase
Solution Approach 1:
The system merges the rendering of multiple cockpit views by sharing common lighting calculations, shadow maps, and scene geometry data across all views. Instead of independently rendering each view, the system performs unified lighting and shadow computations once, then reuses this data across multiple viewports, significantly reducing the time penalty for rendering multiple simultaneous views.
Solution Approach 2:
The rendering engine is designed with universal data structures and computation pipelines that serve multiple cockpit views simultaneously. A single set of lighting and shadow calculations serves all active views, making the rendering system multi-functional and efficient at handling varying numbers of concurrent views without linearly increasing processing time.
3Measurement precision
If all cockpit model parts are updated every frame, then the visual accuracy is improved, but the processing load increases excessively
Solution Approach 1:
The system updates only the subset of cockpit model parts that are currently visible or relevant to the active cockpit views, rather than refreshing all instruments and controls every frame. This partial action approach maintains visual accuracy for displayed elements while avoiding the excessive processing load of updating the entire cockpit model unnecessarily.
Solution Approach 2:
The rendering system applies different update frequencies and quality levels to different cockpit model parts based on their importance and visibility. Critical instruments in the current field of view receive full updates with high visual accuracy, while less important or off-screen elements use reduced update rates or lower fidelity representations, optimizing the balance between visual accuracy and processing load.

AI summary
A simulator is disclosed. A cockpit model comprising a plurality of cockpit model parts that collectively correspond to a simulated cockpit in a simulated vehicle is maintained. For each frame of a plurality of frames, a plurality of cockpit view frustums are determined, each cockpit view frustum corresponding to a different cockpit view of a plurality of cockpit views of the simulated cockpit. Shared cockpit scene information comprising a set of cockpit model parts that are within any of the plurality of cockpit views is generated based on the plurality of cockpit view frustums. A processing device submits to a graphics processing unit (GPU) the shared cockpit scene information and GPU instructions that direct the GPU to generate a plurality of cockpit view images that correspond to the plurality of cockpit views from the shared cockpit scene information. The GPU generates the plurality of cockpit view images.
