Applies 4x4 homogenous matrix transformations to xyz vertices.
tfg.rendering.utils.transform_homogeneous(
matrices: type_alias.TensorLike, vertices: type_alias.TensorLike
) -> tf.Tensor
The vertices are input and output as as row-major, but are interpreted as
column vectors multiplied on the right-hand side of the matrices. More
explicitly, this function computes (MV^T)^T where M represents transformation
matrices and V stands for vertices.
Since input vertices are xyz they are extended to xyzw with w=1.
Args |
