coordinate_math

Synopsis

coordinate_math performs mathematical operations on fields coordinates using V expressions.

Input Port

in_field1	Mesh
in_field2	Mesh
in_field3	Mesh
in_field4	Mesh
ui_parent	user interface parent object

Parameters

output nspace	UIslider	number of coordinate dimensions in the output mesh
X operation	UItext	expression for X coordinate of output mesh
Y operation	UItext	expression for Y coordinate of output mesh
Z operation	UItext	expression for Z coordinate of output mesh

Output Port

out_fld	output mesh
out_obj	output renderable object

Description

coordinate_math performs mathematical operations on one to four input meshes. You can select the number of output coordinates (out nspace) and type in any valid V expression for each of X, Y and Z coordinates

Input

in_field n

The input field(s) must be any type of mesh. You can use from 1 to 4 inputs. When typing the expression, you refer to them as #1, #2, #3, and #4. You refer to individual coordinates in the expression as x, y or z. For example if you want to refer to X coordinate of the first input you would use #1x in the expression, if you want to refer to Z coordinate of the second input you should use #2z in the expression.

Operations involving two or more meshes require that their coordinates be the same length (nnodes must be equal).

ui_parent

A port for connecting to a user interface object that contains the macro's widgets. By default, it is connected to the default user interface object in the application in which the macro is instanced. (This default connection is not drawn.)

Parameters

X, Y, Z operations

UItext. Any valid V mathematical expression. Do not enclose in quotes or terminate with a semi-colon (that is, ";"). For example, the following expression converts input coordinates specified in the Polar coordinate system into output Cartesian coordinates:

X #1x*cos(#1y)

#1x*sin(#1y)

Output Port

out_fld

The output mesh containing coordinates that are a result of the computation.

out_obj

This is a renderable version of the output field.
