This operator performs various space conversions of 3D positional data for uv shading purposes. The available space conversions are:
Texture (string value "texture") Object (string value "object") Normalized Device Coordinate (string value "ndc") World (Unchanged) (string value "world")
Texture option takes a position in world space and converts it to
shader space. The
Object option takes a position in world space and
converts it to object space. The
NDC option takes a position in world
space and puts it in the normalized device coordinate space (screen
World option leaves the incoming data untouched.
If the position (
P) input is not connected, the global variable by the
same name will be used instead.
