Renders a voxel grid using the absorption-only model, as described in "Escaping Plato's Cave: 3D Shape From Adversarial Rendering" (Henzler 2019).
tfg.rendering.volumetric.absorption.render(
voxels: type_alias.TensorLike,
absorption_factor: tf.float32 = 0.1,
cell_size: tf.float32 = 1.0,
axis: int = 2,
name: str = 'absorption_render'
) -> tf.Tensor
Note |
In the following, A1 to An are optional batch dimensions.
|
Args |
voxels
|
A tensor of shape [A1, ..., An, Vx, Vy, Vz, Vd] , where Vx, Vy, Vz
are the dimensions of the voxel grid and Vd the dimension of the
information stored in each voxel (e.g. 3 for RGB color).
|
absorption_factor
|
A scalar representing the density of the volume.
|
cell_size
|
A scalar representing the size of a cell.
|
axis
|
An index to the projection axis (0 for X, 1 for Y or 2 for Z).
|
name
|
A name for this op. Defaults to "absorption_render".
|
Returns |
A tensor of shape [A1, ..., An, Vx, Vy, Vd] representing images of size
(Vx,Vy).
|
Raises |
ValueError
|
If the shape of the input tensors are not supported.
