tfg.rendering.interpolate.interpolate_vertex_attribute

Interpolate a single vertex attribute across the input framebuffer.

tfg.rendering.interpolate.interpolate_vertex_attribute(
    attribute: tf.Tensor,
    framebuffer: tfg.rendering.framebuffer.Framebuffer,
    background_value: Optional[Union[tf.Tensor, Iterable[float]]] = None
) -> tfg.rendering.framebuffer.RasterizedAttribute

attribute 2-D or 3-D vertex attribute Tensor with shape [batch, num_vertices, num_channels] or [num_vertices, num_channels].
framebuffer Framebuffer to interpolate across. Expected to contain barycentrics, vertex_ids, and foreground_mask.
background_value 1-D Tensor (or convertible value) with shape [num_channels] containing the value to use for background pixels. If None, defaults to zero.

A RasterizedAttribute containing the per-pixel interpolated values.
