tfg.rendering.reflectance.lambertian.brdf

Evaluates the brdf of a Lambertian surface.

Note:

In the following, A1 to An are optional batch dimensions, which must be broadcast compatible.

Note:

The gradient of this function is not smooth when the dot product of the normal with any light is 0.0.

direction_incoming_light A tensor of shape [A1, ..., An, 3], where the last dimension represents a normalized incoming light vector.
direction_outgoing_light A tensor of shape [A1, ..., An, 3], where the last dimension represents a normalized outgoing light vector.
surface_normal A tensor of shape [A1, ..., An, 3], where the last dimension represents a normalized surface normal.
albedo A tensor of shape [A1, ..., An, 3], where the last dimension represents albedo with values in [0,1].
name A name for this op. Defaults to "lambertian_brdf".

A tensor of shape [A1, ..., An, 3], where the last dimension represents the amount of reflected light in any outgoing direction.

ValueError if the shape of direction_incoming_light, direction_outgoing_light, surface_normal, shininess or albedo is not supported.
InvalidArgumentError if at least one element of albedo is outside of [0,1].
