Problem

Existing graphics rendering systems lack efficient methods for optimizing graphics operations across multiple frames and GPUs, leading to suboptimal frame rates and resource management in complex graphics processing tasks.

Innovation Solution

A software development kit (SDK) with a new API that analyzes scene trees, enables auto-batching, uses index and vertex buffers, generates effects nodes, and manages textures to optimize rendering operations, automatically determining the best GPU draw calls and resource allocation for improved performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual customization is used for specific GPUs, then rendering optimization can be tailored to hardware, but device complexity and programming difficulty increase

Engineering Contradiction:
Improverendering performanceVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The rendering system automatically analyzes the scene graph and generates optimized draw calls without requiring manual customization for specific GPU models. The system self-adapts to the hardware by using abstraction layers that translate high-level rendering commands into GPU-specific instructions, eliminating the need for developers to manually optimize for each GPU while maintaining high rendering performance

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements a universal rendering architecture that can handle multiple GPU types through a common interface. The scene graph representation and draw call generation system are designed to be GPU-agnostic, allowing the same rendering pipeline to work across different hardware platforms without requiring platform-specific customization, thus reducing device complexity while maintaining productivity

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If draw calls are processed individually, then rendering flexibility is maintained, but GPU activity increases and frame rates decrease

Engineering Contradiction:
Improveframe rateVSAvoidGPU activity
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent implements draw call consolidation by analyzing the scene graph to identify and merge multiple individual draw calls into fewer batched operations. The system groups draw calls by shared resources such as textures, vertex buffers, and shader programs, reducing the total number of GPU command submissions. This batching approach maintains rendering flexibility while significantly reducing GPU activity and improving frame rates

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If resource allocation is manual, then resource management can be optimized, but time consumption and complexity increase

Engineering Contradiction:
Improverendering efficiencyVSAvoidoptimization time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent implements automatic resource allocation by pre-analyzing the scene graph during the rendering setup phase to determine optimal resource usage. The system pre-allocates textures, vertex buffers, and shader programs based on the scene requirements, eliminating the need for manual resource management during runtime. This preliminary analysis automates resource optimization while reducing the time required for manual configuration

Inventive Principle:
Principle #10Preliminary action
