Справка Houdini на русском Nodes VOP nodes

From Polar VOP node

Converts polar coordinates to cartesian coordinates.

Given U (latitude), V (longitude) and a radius, this node outputs the 3D position of the specified point in cartesian (XYZ) space.

This is equivalent to:

x = radius * sin(v)*cos(u);
y = radius * sin(v)*sin(u);
z = radius * cos(v);

Parameters

Input space

How this node interprets the input UV coordinates. Values outside the natural range for an interpretation will wrap periodically.

Unit

U and V coordinates are in the range (0, 1).

Radians

U and V coordinates are in radians. U is in the range (0, 2*pi) while V is in the range (0, pi).

Degrees

U and V coordinates are in degrees. U is in the range (0, 360) while V is in the range (0, 180).
