Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for representing displacement-mapped surfaces require significant memory and processing bandwidth due to the large number of floats needed to represent complex surfaces, leading to increased costs and inefficiencies.
Innovation Solution
The method involves defining local vectors on the displacement-mapped surface, determining global vectors based on subsets of these local vectors, and using these global vectors to form a representation of the surface, reducing the number of floats required and thereby decreasing memory and processing demands.

Engineering Contradiction Analysis
1Measurement precision
If a predetermined number of floats is used to represent each section of the displacement-mapped surface, then the representation quality is maintained, but the memory capacity and processing bandwidth requirements increase significantly
Solution Approach 1:
The patent changes the parameter representation from using a fixed predetermined number of floats per section to using a variable number of global vectors. The number of global vectors is dynamically determined based on the complexity of the displacement-mapped surface sections, allowing the system to use fewer floats for simpler sections while maintaining sufficient representation quality. This parameter change directly reduces the total quantity of floats needed while preserving measurement precision.
Solution Approach 2:
The patent introduces dynamic adaptability in the representation scheme by determining the number of global vectors based on the actual complexity of each displacement-mapped surface section. Rather than using a static predetermined number of floats for all sections, the system dynamically adjusts the representation density according to the specific section's complexity, thereby optimizing the balance between representation quality and data quantity.
2Quantity of substance
If the number of floats is reduced to decrease memory and processing requirements, then the representation quality may deteriorate, but the patent maintains high-quality representation through global vectors
Solution Approach 1:
The patent creates a universal representation mechanism using global vectors that can represent different types of displacement-mapped surface sections with varying complexities. The global vectors serve multiple functions: they capture the essential geometric characteristics of the surface, enable efficient memory storage, and maintain rendering quality. This universal approach allows the same representation technique to handle both simple and complex sections effectively.
Solution Approach 2:
The patent changes the representation parameters from fixed float arrays to variable global vector sets. By determining the number of global vectors based on section complexity, the system achieves efficient compression while preserving the necessary geometric information for high-quality rendering. This parameter transformation enables the system to reduce data quantity without sacrificing representation fidelity.
3Device complexity
If a fixed allocation of floats is used for all sections, then the system is simple to implement, but the cost increases due to the need to allocate enough floats for the most complex sections
Solution Approach 1:
The patent applies local quality by assigning different numbers of global vectors to different sections based on their individual complexity. Rather than using a uniform fixed allocation across all sections, the system tailors the representation density to match the local requirements of each displacement-mapped surface section. This allows simple sections to use fewer floats while complex sections receive sufficient representation, optimizing overall memory usage.
Solution Approach 2:
The patent introduces dynamic allocation of global vectors based on section complexity. The system determines the appropriate number of global vectors for each section during processing, allowing flexible memory allocation that adapts to the actual computational needs of each section. This dynamic approach replaces the static fixed allocation model, enabling cost-effective resource utilization.

AI summary
A system and method for constructing a displacement-mapped surface representation are presented. An exemplary method includes defining a plurality of local vectors emanating from the displacement-mapped surface, each local vector extending at a local angle from a local position disposed on the displacement-mapped surface. The method further includes determining first and second global vectors for respective first and second subsets of the local vectors, the first global vector determined as a function of the first subset vectors' local positions and local angles, and the second global vector determined as a function of the second subset vectors' local positions and local angles. The first and second global vectors are utilized to form a representation of the displacement-mapped surface.
