tensor-3d-grid

schema/objects/tensor-3d-grid/1.3.0/tensor-3d-grid.schema.json

Represents a three-dimensional tensor grid where cells may have different sizes.

The grid implements spatial properties including a coordinate reference system and bounding box in world coordinates.

The grid origin is defined in three dimensions, along with rotation (defined per the Rotation schema component).

The size of the grid is specified in cells (see size), with each cell potentially having different dimensions along the x, y, and z axes (see grid_cells_3d).

Fields cell_attributes and vertex_attributes accept a variety of scalar values (see One of Attribute component), attached to either the cells (of length grid_size_x * grid_size_y * grid_size_z) or vertices (of length [grid_size_x + 1] * [grid_size_y + 1] * [grid_size_z + 1]).
