Dynamic Video Texture Mapping on 3D Geometric Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D video mapping technologies using static pictures as texture mapping fail to engage viewers fully, limiting the information acquisition and immersive experience due to fixed picture information on surfaces.
Innovation Solution
A method where video frames are mapped onto the surfaces of a cubic geometric body based on pixel point and vertex position information, allowing dynamic video playback that enhances viewer engagement and spatial immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If static pictures are used as texture mapping on 3D model surfaces, then the implementation is simple and straightforward, but the picture information is fixed and cannot fully engage viewer interest
Solution Approach 1:
The patent transforms static picture texture mapping into dynamic video texture mapping. Video frames are continuously updated and mapped onto the 3D model surfaces, replacing fixed images with moving visual content. This dynamic approach maintains implementation simplicity while significantly increasing information delivery and viewer engagement through continuous visual changes.
2Ease of manufacture
If static pictures are updated at a set time interval, then the implementation remains simple, but less picture information can be acquired and viewing interest cannot be fully engaged
Solution Approach 1:
The patent implements continuous video frame mapping where each frame of the video is sequentially mapped onto the 3D model surfaces in real-time. This continuous action replaces periodic static picture updates, ensuring uninterrupted visual information flow. The video playback continuously refreshes the texture mapping, maximizing information delivery efficiency while maintaining straightforward implementation through standard video playback mechanisms.
3Device complexity
If static pictures are used on 3D model surfaces, then the system complexity is low, but the viewing experience and spatial immersion are limited
Solution Approach 1:
The patent enhances viewing experience quality by introducing dynamic video content to the 3D model surfaces. The video frames provide moving visual information that creates a more immersive and engaging spatial experience. Despite this enhancement, the system complexity remains low because the solution uses standard video playback and texture mapping techniques already integrated into 3D rendering pipelines.

AI summary
In a method for displaying video, a first target surface of a geometric body on which a first target video is to be displayed is determined. Pixel point sets corresponding to respective video frames of the first target video are obtained. Each of the respective video frames is mapped to the first target surface based on a mapping relationship between position information of pixel points in the pixel point sets of the respective video frame and position information of a plurality of vertices on the first target surface. The respective video frames include a target video frame that is displayed on the first target surface based on the mapping of the target video frame to the first target surface. The first target video is displayed on the first target surface of the geometric body based on the mapping of the respective video frames to the first target surface.
