Solution Overview
Problem
Current computer systems with specialized processing units, such as GPUs, face inefficiencies in graphics rendering due to the need for 'on the fly' data conversion, which slows down the rendering process.
Innovation Solution
Creating an optimized graphics rendering tree that is specifically formatted and organized for the GPU, prior to rendering, to enhance performance by eliminating the need for real-time data conversion and maximizing the GPU's efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data is converted on the fly during rendering, then the system can maintain flexibility in data processing, but the rendering speed decreases
Solution Approach 1:
The patent applies preliminary action by creating an optimized graphics rendering tree in advance, before the actual rendering process. The CPU prepares the object tree with all necessary data conversions and optimizations beforehand, so that the GPU receives pre-processed data in the optimal format. This eliminates the need for 'on the fly' data conversion during rendering, thereby improving rendering speed while managing complexity through advance preparation.
2Productivity
If data is pre-formatted for GPU, then rendering efficiency improves, but the initial processing time increases
Solution Approach 1:
The system performs preliminary formatting of graphics data by creating an object tree structure that is optimized for GPU processing before rendering begins. This includes organizing scene objects, materials, and lighting data into a hierarchical tree structure with appropriate data formats. The time investment in this preliminary processing stage is traded off against significantly improved rendering efficiency during the actual graphics rendering process.
Solution Approach 2:
The patent creates a copy of the scene data in an optimized format (the object tree) that is specifically tailored for GPU processing. Instead of repeatedly converting the same scene data during rendering, the system creates one optimized copy that can be efficiently processed by the GPU multiple times, reducing the time penalty of initial processing while maintaining high rendering efficiency.
3Productivity
If a specialized processing unit is used, then specific tasks are performed more efficiently, but the system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the graphics processing tasks between two specialized processing units: the CPU for creating and managing the object tree structure, and the GPU for executing the actual graphics rendering. This segmentation allows each processor to be optimized for its specific function, with the CPU handling complex data organization and the GPU handling parallel graphics computations, thereby improving overall task execution efficiency while managing system complexity through clear functional division.
Solution Approach 2:
The object tree structure serves as an intermediary data structure that bridges the CPU and GPU. It is created by the CPU in a format that is optimized for GPU consumption, acting as a mediator that translates between the general-purpose processing capabilities of the CPU and the specialized graphics processing capabilities of the GPU. This intermediary structure simplifies the interface between the two processors and enables efficient collaboration.

AI summary
A system includes a memory, a specialized processing unit and a processor. The processor receives data from a user and creates a first set of objects in a first structure based on the data. The system further creates, contemporaneously with the creation of the first set of objects and based on the first set of objects in the first structure, a second set of objects in a second structure, where the second set of objects is optimized for use by the specialized processing unit, and stores the first and second sets of objects in the memory. The specialized processing unit executes an algorithm based on the second set of objects.
