Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional modeling systems face reproducibility issues when the height of voxels in the lamination direction differs from the lamination interval, leading to degradation in the representation of three-dimensional shapes.

A three-dimensional shape data editing apparatus that adjusts voxel heights to match the lamination interval of the modeling system, ensuring the represented shape remains similar to the original, by converting voxel heights and adjusting the number of voxels in the lamination direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the height of voxels in the lamination direction is simply switched into the lamination interval, then the data compatibility is improved, but the reproduction precision of the original three-dimensional shape deteriorates
Solution Approach 1:
The invention divides the voxel height adjustment process into multiple segments: identifying original voxel heights, comparing with lamination intervals, and applying different editing strategies (keeping original, rounding up, or rounding down) based on the comparison results. This segmentation allows preservation of shape fidelity while achieving data compatibility.
Solution Approach 2:
The invention changes the parameter of voxel height to match lamination intervals while maintaining shape similarity. By systematically adjusting voxel heights to correspond to lamination intervals and modifying the number of voxels accordingly, the system achieves both data compatibility and reproduction precision.
2Manufacturing precision
If the voxel height is adjusted to match the lamination interval, then the modeling accuracy is improved, but the complexity of data processing increases
Solution Approach 1:
The invention performs preliminary actions by pre-identifying all voxels whose heights differ from lamination intervals before actual modeling. This preliminary identification and systematic editing approach simplifies the overall data processing complexity while ensuring modeling accuracy.
Solution Approach 2:
The invention systematically changes voxel height parameters to match lamination intervals through defined editing rules. This parameter transformation approach, while adding processing steps, provides a clear and automated methodology that manages complexity through structured procedures.
3Manufacturing precision
If different voxel heights are used to represent fine details, then the shape fidelity is improved, but the compatibility with fixed lamination interval systems deteriorates
Solution Approach 1:
The invention applies local quality by differentiating between voxels that require height adjustment and those that maintain original heights. The editing unit selectively processes only those voxels whose heights differ from lamination intervals, preserving local shape fidelity where necessary while ensuring overall system compatibility.
Solution Approach 2:
The invention changes voxel height parameters selectively to match lamination intervals only where necessary, maintaining shape fidelity in critical areas while achieving system compatibility overall. This targeted parameter transformation resolves the contradiction between fine detail representation and system compatibility.

AI summary
A three-dimensional shape data editing apparatus includes an editing unit that edits three-dimensional shape data so that a three-dimensional shape represented by using a voxel having a height of a lamination interval is similar to an original three-dimensional shape represented by the three-dimensional shape data in a case where the height of the voxel in a lamination direction of the three-dimensional shape data representing the three-dimensional shape by a set of plural voxels is different from the lamination interval of a three-dimensional modeling apparatus that models the three-dimensional shape.
