Panoramic Video Rendering with Dynamic Viewer Perspective Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual reality systems limit user perspective to first-person views, restricting immersive storytelling and narrative flexibility, especially when viewed on non-VR devices.
Innovation Solution
Implementing cinematographic elements and a reference point within video content to allow dynamic perspective changes, enabling viewers to adjust their field of view beyond first-person constraints, using traditional movie techniques like camera angles and edits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional virtual reality systems use first-person perspective views, then user immersion in the virtual environment is improved, but narrative flexibility and storytelling capability deteriorate
Solution Approach 1:
The system dynamically switches between first-person and third-person perspectives based on narrative requirements. The perspective is not fixed but can change throughout the video content, allowing the story to adapt its viewpoint while maintaining user immersion. This resolves the contradiction by making the perspective system flexible rather than static.
Solution Approach 2:
The video content generation system serves multiple functions: it creates both immersive first-person experiences and flexible third-person storytelling sequences. By integrating both perspective types into a single system, the patent achieves narrative versatility without requiring separate systems, thus managing complexity while improving adaptability.
2Adaptability or versatility
If virtual reality content is designed for immersive first-person views, then user engagement is improved, but compatibility and viewing experience on non-VR devices deteriorate
Solution Approach 1:
The video content is segmented into different perspective segments (first-person and third-person) that can be independently rendered. This segmentation allows the same content to be adapted for different viewing devices - VR devices receive the immersive first-person segments while non-VR devices can view the third-person segments, thus improving device compatibility without overly complicating the overall content structure.
Solution Approach 2:
The system changes key parameters of the video content including perspective angle, field of view, and camera positioning based on the target device type. By adjusting these parameters, the same base content can be optimized for both VR and non-VR devices, improving compatibility while managing structural complexity through systematic parameter variation.
3Adaptability or versatility
If traditional movie elements are incorporated into panoramic video content, then narrative control is improved, but production complexity increases
Solution Approach 1:
The system introduces an intermediary layer - a video content generation system with built-in cinematographic tools - that mediates between the raw 3D environment data and the final panoramic video output. This intermediary provides traditional movie elements like camera angles, transitions, and editing capabilities without requiring manual complex production processes, thus improving narrative control while simplifying content creation.
Solution Approach 2:
The system copies and adapts proven cinematographic techniques from traditional filmmaking into the virtual reality content creation process. By implementing standardized camera models, transition effects, and editing patterns that mirror traditional movie production, the system provides familiar narrative control tools while streamlining the production process through established methodologies rather than requiring entirely new complex workflows.

AI summary
A process for generating dynamic panoramic video content comprises receiving an animation having an environment and creating a timeline for the animation having the environment. The process further comprises receiving cinematographic elements, which include a reference point and a panoramic angle. A position of the reference point within the animation having the environment is based on the timeline, and the panoramic angle that includes a range of possible fields of view from the reference point. The animation having the environment is rendered based on the timeline and the cinematographic elements to create a rendered animation. A field of view with an angle that is less than the panoramic angle is defined. Ultimately, an export animation is created based on the rendered animation, where the export animation allows a viewer to adjust a direction of the field of view from the reference point when the viewer is watching the export animation.
