Generates a M-D uniform axis-aligned grid.
tfg.geometry.representation.grid.generate(
starts, stops, nums, name='grid_generate'
)
Warning |
This op is not differentiable. Indeed, the gradient of tf.linspace and
tf.meshgrid are currently not defined.
|
Note |
In the following, B is an optional batch dimension.
|
Args |
starts
|
A tensor of shape [M] or [B, M] , where the last dimension
represents a M-D start point.
|
stops
|
A tensor of shape [M] or [B, M] , where the last dimension
represents a M-D end point.
|
nums
|
A tensor of shape [M] representing the number of subdivisions for
each dimension.
|
name
|
A name for this op. Defaults to "grid_generate".
|
Returns |
A tensor of shape [nums[0], ..., nums[M-1], M] containing an M-D uniform
grid or a tensor of shape [B, nums[0], ..., nums[M-1], M] containing B
M-D uniform grids. Please refer to the example below for more details.
|
Raises |
ValueError
|
If the shape of starts , stops , or nums is not supported.
|
Examples |

Generates a 3x5 2d grid from -1.0 to 1.0 with 3 subdivisions for the x
axis and from -2.0 to 2.0 with 5 subdivisions for the y axis. This lead to a
tensor of shape (3, 5, 2).
