[FORMul[a]RCH]

This definition gives attraction or repulsion forces to points and can switch between the two

LOGIC

1. Measure the distance between source points and attraction / repulsion points

2. Manipulate the strength and coverage area of the forces

3. Create a switch to choose between attraction or repulsion forces

4. Use the data to control some variable (scale, height, movement, rotation, ect)

GH Version

0.8.0066

Tip

Attraction and repulsion based on distance are a major concept of associative modeling.

Variations in the "strength & coverage" mathematics such as adding sin functions,

multiplications, or other functions can make the attractor / repeller have new and interesting results.

Do not forget, the results of attractors / repellers can be used to control virtually anything, here we

control radius of a circle, try it for many things.

GH: SINE TOWER

This work is licensed under a Creative Commons Attribution 4.0 International License.

GRASSHOPPER SINE TOWER

This definition takes a closed curve and creates a single surface tower via sine scaling

LOGIC

1. Create a closed curve

2. Copy the curve along the divisions of a line

3. Rotate and scale the copied curves with interval and sine functions

4. Loft the curves to make one surface

GH Version

0.8.0066

Tip

For more interesting results make a closed reference curve

that is manipulated in both the x,y,and z direction. Also, replace

the sine component with a cosine component to reverse the effects.

Since the result is one surface, try adding box morph techniques

for more intricate surface designs.

GH: BOX MORPH

This work is licensed under a Creative Commons Attribution 4.0 International License.

GRASSHOPPER BOX MORPH

This definition morphs geometry into surface boxes

LOGIC

1. Create a surface

2. Divide the surface into boxes

3. Create an object to panelize

4. Morph the object into the boxes along the surface

GH Version

0.8.0066

Tip

To add multiple objects per box, right click the brep component (brep to panelize)

and select set multiple breps.Then right click U input of bounding box component (boundary)

and set boolean to true. Finally, right click the box morph component (morph) and set to cross reference.

GH: SURFACE BLEND

GRASSHOPPER SURFACE BLEND

This definition creates a surface by blending between two surfaces.

LOGIC

1. Create two surfaces to blend between

2. Divide both surfaces with points

3. Connect the points between surfaces with lines

4. Slide points along the lines
5. Create new points with curves
6. Loft curves to build the blended surface

GH Version

0.9.0065

Tip

Typically it is best to create one start surface, then copy it, and move / manipulate the copy to use

as the other start surface. This ensures the surfaces have corresponding UV coordinates. If any twisting

or crossing occurs with the lines between the surfaces try rebuilding one of the surfaces to match UV

or try components like flip matrix and flip surface.

GH: SPIRAL MIRROR

This work is licensed under a Creative Commons Attribution 4.0 International License.

GRASSHOPPER SPIRAL MIRROR

This definition creates a doubly periodic surface by mirroring a trimmed spiral.

LOGIC

1. Create a spiral surface

2. Double the spiral surface back to back

3. Trim the spiral edges with a square

4. Mirror the trimmed spiral surface to generate a symmetric form

GH Version

0.8.0066

Tip

Forms like this love mirroring, add more mirror sequences to grow larger systems

and also try box morphing this form onto surfaces and into custom twisted boxes.

2. Remove exterior faces

3. Move Voronoi cells away from each other

4. Loft together common faces

5. Create mesh and smooth connections

In the section "move voronoi cells away from each other" try replacing the volume component

inputted into B of Vec2Pt with a referenced point from rhino for different overall skeleton shapes.
