3D Trajectory Effect Rendering for Immersive AR Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing technologies lack the capability to effectively simulate the process of drawing patterns with specific materials in real-world scenarios, resulting in limited richness and interest in effect videos generated using augmented reality (AR) effect props.
Innovation Solution
A method and apparatus for processing effect videos that involve obtaining current position information of a target touch point, determining a two-dimensional trajectory effect consistent with the motion trajectory of the target touch point, and displaying a three-dimensional trajectory effect from multiple angles when a three-dimensional display condition is met, thereby enhancing the realism and engagement of the effect video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional effect props are used in AR field, then video generation is simple, but the richness and interest of video content is poor
Solution Approach 1:
The patent transitions from traditional two-dimensional effect props to three-dimensional trajectory effects. By detecting touch point coordinates over time and generating 3D spatial trajectories, the system creates immersive visual effects that simulate real-world drawing processes with materials like sugar painting, significantly enhancing video content richness while maintaining manageable complexity through software-based processing.
2Reliability
If 3D trajectory effect is displayed from multiple angles, then immersion and realism are enhanced, but processing complexity increases
Solution Approach 1:
The system dynamically adjusts the display of 3D trajectory effects based on real-time touch point movement. The trajectory effect is generated and updated continuously as the user moves their finger across the screen, allowing the effect to adapt to changing user actions while maintaining realistic simulation without requiring overly complex pre-processing of all possible trajectories.
Solution Approach 2:
The patent creates virtual copies of real-world drawing processes by mapping touch point coordinates to simulated material trajectories. Instead of physically manipulating materials, the system generates digital representations that replicate the visual appearance and motion characteristics of real drawing actions, reducing physical complexity while maintaining realism.
