Real-Time Video Exploration for Interactive 3D Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video production methods limit viewer interaction, as scenes are rendered from pre-selected camera viewpoints, restricting exploration and customization of 3D modeled worlds within pre-rendered videos.
Innovation Solution
A real-time video exploration system that allows users to interactively explore and customize 3D modeled worlds by generating and rendering new video content in real-time using network-based computation resources, enabling users to change viewing positions, manipulate objects, and modify graphics effects within pre-recorded videos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pre-rendered video with fixed camera viewpoints is used, then production efficiency is improved, but viewer interaction and exploration capability deteriorate
Solution Approach 1:
The system pre-renders video content with fixed camera viewpoints to ensure production efficiency, while simultaneously pre-processing 3D scene data and object information in advance. This preliminary preparation enables rapid real-time rendering when users interact, resolving the contradiction by having both pre-rendered content and pre-processed 3D data ready beforehand.
Solution Approach 2:
The system dynamically switches between pre-rendered video content and real-time rendered content based on user interaction. When users interact with objects or change viewpoints, the system dynamically renders new video content from the pre-processed 3D scene data, allowing both efficient pre-rendering and interactive real-time rendering to coexist.
2Adaptability or versatility
If real-time rendering of new video content is enabled, then viewer interaction and customization capability are improved, but computational resources and processing time increase
Solution Approach 1:
Instead of rendering entire scenes in real-time, the system selectively renders only the portions of scenes that users interact with or request to view from different angles. This partial rendering approach maintains interaction capability while significantly reducing computational resource requirements compared to full scene rendering.
Solution Approach 2:
The system uses pre-processed 3D scene data as an intermediary between pre-rendered video and real-time rendering. This intermediate representation contains essential geometric and material information that enables efficient real-time rendering without requiring complete scene re-rendering, thus reducing computational power requirements.
3Adaptability or versatility
If complete 3D scene data is processed, then exploration capability is improved, but data processing complexity and storage requirements increase
Solution Approach 1:
The system segments 3D scene data into discrete objects and spatial regions, processing and storing only essential attributes for each segment. This segmentation allows the system to manage complex 3D data more efficiently while maintaining the ability to render complete scenes when needed, as each segment can be independently processed and combined.

AI summary
A real-time video exploration (RVE) system that allows users to pause, step into, move through, and explore 2D or 3D modeled worlds of scenes in a video. The RVE system may allow users to select and manipulate objects within a scene, and to modify an object by adding or removing accessories from the object or otherwise customizing the object according to the user's preferences or desires. The RVE system may also provide an interface or interfaces via which the user can obtain additional information for the object, customize the object, be given a price or price(s) for the object as customized, and purchase the object as specified if desired.
