Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for storing and rendering three-dimensional object details, such as color and geometry, in meshes are inefficient, costly, and prone to distortion, especially in clinical applications where accurate and real-time rendering is required.
Innovation Solution
Tessellate the mesh to generate vertices, serialize these vertices, calculate and store values for each vertex, and use tessellation parameters to efficiently store and render accurate color and geometric information without increasing file size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a higher resolution mesh is used to store more information, then the detail accuracy is improved, but the file size increases
Solution Approach 1:
The mesh is divided into multiple patches, and each patch is processed independently through tessellation. This segmentation allows the system to store information efficiently by only processing and storing data for visible patches, reducing overall file size while maintaining detail accuracy where needed.
Solution Approach 2:
The system uses dynamic tessellation where the level of detail is adjusted based on view distance and importance. Patches closer to the camera or marked as important receive higher tessellation levels for greater detail, while distant patches use lower levels, creating a dynamic balance between accuracy and file size.
2Productivity
If tessellation is used to add detail dynamically, then the rendering speed is improved, but the complexity of the system increases
Solution Approach 1:
Tessellation parameters and importance values are pre-calculated and stored with the mesh data before rendering. During rendering, the system only needs to apply these pre-computed parameters rather than calculating them in real-time, which maintains rendering speed while managing system complexity through preparation work done beforehand.
Solution Approach 2:
The system introduces an intermediary layer of tessellation parameters and importance values that mediate between the base mesh and the final rendered output. This intermediary structure simplifies the rendering process by providing pre-processed guidance information, reducing the computational complexity during actual rendering while enabling dynamic detail adjustment.
3Loss of information
If more vertices are added to represent details, then the information accuracy is improved, but the computational cost increases
Solution Approach 1:
The system applies different levels of information accuracy to different regions of the mesh based on their importance values and distance from the camera. Critical areas such as dental features receive high-resolution tessellation with accurate information, while less important areas use lower resolution, optimizing the balance between information accuracy and computational cost.
Solution Approach 2:
The system changes the tessellation parameters dynamically based on patch importance and view conditions. By adjusting the tessellation level parameter rather than uniformly increasing vertex count across the entire mesh, the system achieves high information accuracy where needed while minimizing overall computational cost through parameter optimization.
