Render an SDF via sphere tracing and display with matplotlib.

Wraps :func:raymarch and shows the result on a plt.Axes.

Parameters

Name	Type	Description	Default
sdf	Callable[[Array], Array]	Signed distance function.	required
camera_pos	Array	Camera position in world space.	jnp.array([5.0, 5.0, 5.0])
look_at	Array	Point the camera looks toward.	jnp.array([0.0, 0.0, 0.0])
light_dirs	Array	Light direction(s), shape (3,) or (N, 3).	jnp.array([0.5, 1.0, 0.3])
light_colors	Array | None	Light color(s), shape (3,) or (N, 3). Defaults to white for every light.	None
resolution	tuple[int, int]	Output image size as (height, width).	(200, 200)
fov	float	Half-width field-of-view parameter.	0.6
max_steps	int	Sphere tracing iterations per ray.	48
max_dist	float	Miss threshold distance.	20.0

shadow_hardness	float	Shadow edge sharpness.	8.0
gamma	float	Gamma correction exponent.	2.2
ambient	float	Constant ambient term (0 = fully black shadows).	0.0
aa_samples	int	Super-sampling anti-aliasing factor.	1
background_color	Array	RGB color for rays that miss all geometry.	jnp.array([0.0, 0.0, 0.0])
refract_steps	int	Interior march steps for glass refraction (0 = disabled).	0
fd_normals	bool	Use finite-difference normals (avoids 2nd-order AD overhead).	False
normal_eps	float	Step size for finite-difference normal estimation.	0.0001
reflect_steps	int	Mirror reflection march steps (0 = disabled).	0
env_map	Array | None	Equirectangular HDR environment map (H, W, 3) used for miss-ray and reflection-miss coloring.	None
ax	plt.Axes | None	Existing matplotlib axes; creates new figure if None.	None
title	str | None	Axes title.	None

Returns

Name	Type	Description
	plt.Axes	The matplotlib axes with the rendered image.
