3D Avatar Rendering via Single Instruction Rasterization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional videoconferencing technologies lack the social interaction and spatial experience of in-person meetings, and face performance issues with large participant numbers due to bandwidth and hardware limitations, leading to slow performance and reduced realism in virtual environments.
Innovation Solution
A computer-implemented method for efficient rendering in a three-dimensional virtual environment using a cross-browser JavaScript library to generate a single instruction for the rendering engine to rasterize identical three-dimensional models, allowing GPU-accelerated animation and optimizing data transfer to improve performance and social interaction by mapping video streams onto avatars.

Engineering Contradiction Analysis
1Quantity of substance
If multiple video streams are placed in the conference, then the number of participants increases, but the performance of videoconferencing systems slows down due to bandwidth and computing hardware limitations
Solution Approach 1:
The patent segments the rendering process by identifying and grouping identical three-dimensional models (avatars) in the virtual environment. Instead of rendering each avatar independently, the system divides the scene into reusable model instances that can be rendered once and reused across multiple participants, reducing the computational load per participant while maintaining the ability to handle large numbers of users
Solution Approach 2:
The patent uses copying by generating a single instruction that references identical three-dimensional models multiple times in the scene. Rather than creating separate rendering instructions for each identical avatar, the system creates one master instruction that can be instantiated repeatedly, allowing the same model to be copied and placed throughout the virtual environment without proportionally increasing rendering complexity
2Manufacturing precision
If conventional rendering methods are used for each three-dimensional model, then rendering accuracy is maintained, but the computing power required increases significantly
Solution Approach 1:
The patent merges identical rendering operations by combining multiple separate draw calls into a single instruction. When the same three-dimensional model appears multiple times in the scene, the system consolidates the rendering commands into one unified instruction that handles all instances simultaneously, maintaining full rendering quality for each instance while dramatically reducing the total computing power required
Solution Approach 2:
The patent creates universal rendering instructions that can serve multiple purposes. A single draw call is designed to be multi-functional, capable of rendering any number of identical avatar models throughout the virtual environment. This universal instruction replaces numerous specialized rendering commands, reducing computational overhead while preserving rendering accuracy across all instances
