Solution Overview

Problem

Existing immersive media technologies lack a robust methodology for mapping Immersive Technologies Media Format (ITMF) specification with different rendering engines, particularly in scenarios where the end client's renderer engine does not support the scene file.

Innovation Solution

A method and apparatus for parsing and translating scene file data into a format compatible with a respective rendering engine, using an ITMF scene parser and converter to map the data into an ITMF scene representation, enabling compatibility with various rendering engines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If ITMF scene file is used for photorealistic rendering, then rendering quality is improved, but compatibility with different rendering engines deteriorates

Engineering Contradiction:

Improverendering qualityVSAvoidcompatibility with rendering engines

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent implements a converter component that acts as an intermediary between the ITMF scene parser and different rendering engines. The converter translates the parsed ITMF scene data into formats compatible with various rendering engines, thereby maintaining both high rendering quality and broad compatibility without requiring direct integration between ITMF and each rendering engine.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If scene file data is directly processed by rendering engine, then processing speed is improved, but adaptability to different engines deteriorates

Engineering Contradiction:

Improveprocessing speedVSAvoidadaptability to rendering engines

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent applies preliminary action by parsing the ITMF scene file in advance and converting it to a standardized intermediate format before rendering. This pre-processing step separates the complex format conversion from the time-critical rendering process, allowing fast rendering execution while maintaining adaptability through the converter component.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If format conversion is performed, then compatibility is improved, but processing complexity is worsened

Engineering Contradiction:

ImprovecompatibilityVSAvoidprocessing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The converter serves as a centralized intermediary that handles all format conversion complexity in one location. This isolates the conversion logic from both the scene parser and rendering engines, making the system easier to maintain and extend. New rendering engines can be added without modifying existing conversion logic, and format changes are contained within the converter.

Inventive Principle:

Principle #24Intermediary (Mediator)
