Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If material IDs are updated for voxels during gameplay, then the appearance and behavior of voxel-based objects become more realistic and dynamic, but the computational complexity and processing time increase
Solution Approach 1:
The system divides the voxel space into multiple update ranges, allowing material updates to be processed in segmented regions rather than globally. This enables selective updating of only those voxel regions that are currently visible or relevant to gameplay, reducing overall computational complexity while maintaining dynamic material updating capability.
Solution Approach 2:
The system performs material updates partially by focusing computational resources on specific update ranges that contain visible objects or areas of player interest. Instead of updating all voxels in the world, only portions requiring material changes are processed, reducing processing time and complexity while still achieving realistic dynamic appearances where needed.
2Adaptability or versatility
If multiple material IDs are allowed per voxel, then the variety of appearances and behaviors for voxel objects increases, but the data storage requirements and processing overhead increase
Solution Approach 1:
Material IDs are pre-assigned to voxels during world generation or loading phases, with multiple material IDs stored in advance for each voxel. This preliminary preparation allows the system to quickly switch between materials during gameplay by simply activating pre-stored material IDs rather than computing or storing extensive material data structures, reducing processing overhead while maintaining material variety.
3Reliability
If display meshes are updated in response to voxel changes, then the visual representation remains synchronized with game events, but the rendering performance may deteriorate
Solution Approach 1:
The system updates display meshes with local quality by focusing rendering updates only on specific regions where material changes have occurred, rather than globally refreshing all meshes. This allows visually critical areas to maintain high synchronization quality while reducing overall rendering workload and maintaining performance.
Solution Approach 2:
Material ID changes are triggered by periodic game events such as collisions, player actions, or time-based conditions. This periodic update approach ensures visual synchronization occurs at meaningful moments in gameplay rather than continuously, reducing unnecessary rendering operations while maintaining reliability of visual representation when changes actually occur.

AI summary
At least one of material IDs is changed to a different material ID for each of voxels corresponding to a voxel update range, and a display mesh is updated in association with updated voxel data. In addition, generating an in-game behavior based on collision determination between a determination mesh in which a material is determined based on at least a plurality of materials ID included in voxel data, and a determination shape corresponding to a determination target, and a virtual space including a display mesh is rendered based on vertex coordinates of the display mesh and a texture corresponding to a material for the display mesh.
