Complex Point

A complex point can be defined by specifying a string describing a relative position between two nodes. The string syntax allows defining a relative positioning or a metric distance.

Relative string syntax:

Metric string syntax:

Cartesian Reference syntax:

Points inside or outside the sampling cube are defined as a Cartesian reference based on their X, Y, Z coordinates (from the Rhino system – Z axis up)

The points are calculated based on this reference to the component space where the X axis is from node 1 to 2, the Y axis is from node 1 to -1 and the Z axis is from node 1 to 3.

For example, the mid point of the cube is noted: X0.5,0.5,0.5

This syntax is interpreted properly when used in the From P column only.

The Cartesian syntax is identified by the letter X as the header. A point is described by its relative Cartesian coordinates from the 0,0,0 origin of the sampling cube and interpolated to the cubical space of the rib structure.

The positioning is in percentage values, and we will introduce a metric option in future release.

The center of the sampling cube is defined as X0.5,0.5,0.5 where the coordinates order match the Rhino X,Y,Z axes.

Example:

Pressing on the button when the ‘Active Component’ toggle is selected builds the sampling cube and show the node mapping on the surface.

We draw 3 polylines defining the loft curves of a pillow shape within the cube.

The mid point of the second profile sampled as ‘X 0.5, 0.682, 0.5′ (Node 1 is the 0,0,0 origin of the cubical space). Populating the surface with loft components creates the pillow shapes within the rib structure space:
