IESDataset

from acron._rplight import IESDataset

class IESDataset

Bases:

This class is used by the IESLoader to generate a LUT texture which is used in the shaders to perform IES lighting. It takes a set of vertical and horizontal angles, as well as a set of candela values, which then are lineary interpolated onto a 2D LUT Texture.

__init__()

This constructs a new IESDataset with no data set.

generate_dataset_texture_into()

This generates the LUT into a given dataset texture. The x-axis referes to the vertical_angle, whereas the y-axis refers to the horizontal angle.

2D Texture Array.

set_candela_values()

This sets the candela values of the dataset. They should be an interleaved 2D array with the dimensions vertical_angles x horizontal_angles. They also should be normalized by dividing by the maximum entry.

set_horizontal_angles()

This sets the list of horizontal angles of the dataset.

set_vertical_angles()

This sets the list of vertical angles of the dataset.
