OvusReference
An ovus
is a shape that looks like an egg. A Change in version 3.8 has extended the syntax of the ovus
object by adding radius
, distance
and precision
controls.
The syntax is as follows:
ovus { Bottom_radius, Top_radius [radius Inner_radius] [distance Vertical_distance] [precision Root_tolerance] [OBJECT_MODIFIERS...] }
Where Bottom_radius is a float value giving the radius of the bottom sphere and Top_radius is a float specifying the radius of the top sphere. The top and bottom spheres are connected together with a suitably truncated lemon, or self intersection of a torus, that is automatically computed so as to provide the needed continuity to the shape. The distance
is a float value that represents the length between the center of the two spheres, defaulting to Bottom_radius. The radius
float value represents the inner circle of the connecting torus and it's default is twice the greater of either Top_radius or Bottom_radius. The precision
float value is the tolerance used for the root solving of the connecting torus. If additional accuracy is required you can now add the sturm
object modifier.


Note: According to the ratio of the radius, the pointy part is the smallest radius, but is not always on top!

object is constructed.
