3D Application Playback System for Debugging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developing and debugging application content for 3D environments is time-consuming and difficult due to challenges in detecting and correcting undesirable application behavior, such as unexpected physics engine interactions, within existing techniques.
Innovation Solution
A method and system for recording and playing back application execution in a 3D environment, using program state information and changes to recreate user interactions, allowing developers to test and review application content by generating a recording of application execution and presenting a playback from different viewpoints, including graphical depictions of user positions and spatialized audio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If developers manually test and debug application content in 3D environments using existing techniques, then they can detect and correct undesirable application behavior, but the process becomes time-consuming and difficult
Solution Approach 1:
The system creates a digital copy of the application execution state by recording program state information at various points during runtime. This recording captures the complete application state including variable values, object positions, and execution flow, allowing developers to replay and examine specific moments without re-running entire test sequences, thereby reducing debugging time while maintaining detection accuracy
Solution Approach 2:
The system performs preliminary recording of application state information during normal execution before debugging is needed. By continuously capturing and storing program state data during application runtime, the system prepares debugging information in advance, eliminating the need for time-consuming manual testing and enabling immediate review of application behavior when issues are detected
2Ease of operation
If developers review application behavior in real-time during execution, then they can immediately identify issues, but they cannot easily re-examine specific points in time or different viewpoints
Solution Approach 1:
The system creates persistent copies of execution state information by recording program state data to storage during application execution. These recorded states can be replayed at any time, allowing developers to re-examine specific moments and analyze application behavior from different perspectives without losing the original execution context, thus improving review convenience while preserving complete execution information
Solution Approach 2:
The system introduces a recording intermediary layer that captures program state information and mediates between the actual application execution and the developer's review process. This intermediary recording mechanism allows developers to access and replay execution states independently of the original runtime, enabling convenient re-examination of specific points in time without interfering with the actual application operation

AI summary
Various implementations disclosed herein include devices, systems, and methods that presents playback of application content within a three-dimensional (3D) environment. An exemplary process presents a first set of views that includes application content provided by the application within a 3D environment. The first set of views are provided from a first set of viewpoints during execution of the application. The process records of the execution of the application based on recording program state information and changes to the application content that are determined based on user interactions, and presents a second set of views including a playback of the application content within the 3D environment based on the recording. The second set of views are provided from a second set of viewpoints that are different than the first set of viewpoints.
