Geometric Shapes¶

Spheres and sticks can annotate molecular scenes or build custom geometry.

from cosmol_viewer import Scene, Sphere, Stick

marker = (
    Sphere(center=[0, 0, 0], radius=0.8)
    .color("#d1495b")
    .roughness(0.4)
)
axis = (
    Stick(start=[0, 0, 0], end=[3, 0, 0], thickness=0.12)
    .color("#00798c")
    .opacity(0.8)
)

scene = Scene()
scene.add_shape(marker)
scene.add_shape(axis)

Sphere.set_center() and Sphere.set_radius() update sphere geometry. Stick.set_start(), Stick.set_end(), and Stick.set_thickness() update stick geometry. Styling methods return the shape so calls can be chained.
