Static isGridCell

▸ isGridCell(surface: MeshSurface): boolean

Overrides ObbGrid.isGridCell

Defined in src/modules/kyub.core.boxel/src/GridInferring/grids/EquilateralTriangleGrid.ts:26

This assesses whether the given surface is eligible to be one cell of this grid.

Parameters:

Name	Type	Description
surface	MeshSurface	-

Returns: boolean
