Voxel Mesh Material Overrides With Reversible State Restoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game technologies face difficulties in incorporating material changes into voxel-based objects while maintaining material information, leading to challenges in returning objects to their original state.
Innovation Solution
A game system and method that utilizes voxel data to manage material changes by setting multiple material IDs for each voxel, updating voxel data ranges, and employing forced change and removal flags to maintain material information, allowing for seamless material transitions and effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a material is changed in voxel data, then the appearance of the object is updated, but the original material information is lost and cannot be returned
Solution Approach 1:
The patent applies preliminary action by setting a forced change flag to ON before material changes occur. This flag preserves the original material information in advance, allowing the object to return to its original state later. The forced change flag is set when material changes are applied through game processing, ensuring that material information is maintained even as the appearance updates.
Solution Approach 2:
The patent uses parameter changes by introducing a forced change flag parameter that controls material ID assignment. When the flag is ON, the system forces the material ID to match the voxel's original material regardless of other material ID settings. This parameter mechanism enables reversible material changes while maintaining the ability to restore original material information.
2Adaptability or versatility
If multiple material IDs are set for each voxel, then material transitions become dynamic, but the data complexity increases
Solution Approach 1:
The patent applies local quality by allowing different voxels to have different numbers of material IDs set based on their forced change flag status. Voxels with the flag ON have restricted material ID assignment (only original material), while voxels with the flag OFF can have multiple material IDs. This localized approach enables dynamic material transitions in specific areas without increasing overall data complexity.
3Productivity
If material information is rewritten, then new materials are applied, but the ability to return to original state is lost
Solution Approach 1:
The patent implements feedback by using the forced change flag to control material ID assignment. When the flag is ON, the system feedback mechanism ensures that only the original material ID can be applied, preventing permanent material changes. This feedback loop maintains material restoration capability while allowing efficient material application when the flag is OFF.

AI summary
A material for a display mesh is determined by setting a plurality of material IDs for each of a plurality of polygons included in the display mesh. A material for a determination mesh is determined by setting a single material ID for each of a plurality of polygons included in the determination mesh. Voxel data further includes a forced change flag for each voxel. A material for the display mesh and a material for the determination mesh are determined, assuming that a voxel whose forced change flag is on has only a material corresponding to the forced change flag irrespective of the material ID set for the voxel.
