<td>Controls the detail used to render a sphere by adjusting the number of vertices of the sphere mesh.
|
|
The default resolution is 30, which creates a fairly detailed sphere definition with vertices every 360/30 = 12 degrees.
|
|
If you're going to render a great number of spheres per frame, it is advised to reduce the level of detail using this function.
|
|
The setting stays active until <b>sphereDetail()</b> is called again with a new parameter and so should not be called prior to every <b>sphere()</b> statement, unless you wish to render spheres with different settings, e.g. using less detail for smaller spheres or ones further away from the camera.
|
|
To control the detail of the horizontal and vertical resolution independently, use the version of the functions with two parameters.</td>
