sphere¶
- sphere(pos=vec(0, 0, 0), radius=2, color=color.cyan)¶
- Parameters:
pos (vector) – Position of center. Default <0,0,0>.
radius (scalar) – Default 1.
color (vector) – Default color.white
size (vector) – Dimensions of a box surrounding the sphere. Default <2,2,2>.
axis (vector) – Default <1,0,0>
A sphere can be made into an ellipsoid by assigning an asymmetrical size.
Attributes used less often:
- sphere(opacity=0.5, shininess=0.2, texture=textures.wood, make_trail=True, canvas=mycanvas, emissive=False)
- Parameters:
opacity (scalar) – Default 1.0; Range 0-1.
shininess (scalar) – Default 0.6; Range 0-1.
emissive (boolean) – Default False. Object glows, losing all shading, if True.
texture (class element or path) – Default None.
visible (boolean) – If False, object is not displayed. Default: True
canvas (object) – Default is scene.
make_trail (boolean) – If True, object leaves a trail when moved. See Attaching a Trail for more options.
up (vector) – A vector perpendicular to the axis.
group (object) – The group to which this object belongs.
Although a sphere does have axis and up attributes, these are not typically useful unless a texture has been applied to the sphere.
simple_sphere¶
In order to look smooth, a sphere is made of a very large number of triangles. Sometimes speed is more important than ultimate beauty. The simple_sphere object has many fewer triangles than a sphere. It can be used just like a sphere, but a large number of simple_sphere objects is displayed very much faster than the same number of regular spheres. For speed, the simple_sphere object is used in the points object and in trails that use points.
