render.make_gradient_sky

render.make_gradient_sky(
    sky_color=(0.2, 0.48, 0.9),
    horizon_color=(0.85, 0.72, 0.52),
    ground_color=(0.18, 0.16, 0.14),
    resolution=(256, 512),
)

Create a simple procedural gradient sky as a (H, W, 3) env-map array.

The latitude axis is split into ground (y < 0) and sky (y ≥ 0), with a smooth cosine blend in between. Suitable as a drop-in replacement for a real HDR file.

Parameters

Name	Type	Description	Default
sky_color	Array | list	RGB color at the zenith (top of the sky).	(0.2, 0.48, 0.9)
horizon_color	Array | list	RGB color at the horizon.	(0.85, 0.72, 0.52)
ground_color	Array | list	RGB color below the horizon.	(0.18, 0.16, 0.14)
resolution	tuple[int, int]	(H, W) of the generated map.	(256, 512)

Returns

Name	Type	Description
	Array	Float32 JAX array of shape (H, W, 3) with values in [0, 1].
