SPONGE LOFT ATTEMPT 1

The shape of this seas sponge is basically circular tubes projecting outwards from a central point at its base. These are hollow and undulate slightly.

Using the loft tool on different sized circles a single tube is generated

Repeating the loft and adjusting the position of the lofting circles makes different sizes around the centre tube

Repeating even further and expand-ing the size while keeping all based on the same base point makes it somewhat close to the sponge im-age.

Modelling with Metaball to create a ridge pattern similar to the brain coral picture

Then extruding those curves upwards to make them 3 dimensional

Then making a 2d line work image with Make2D and extruding those curves into another 3 dimensional form to give them another dimension which also creates the ribbing effect like in the Brain Coral im-

BRANCH MODEL

The simple line geometry I put through different lofting outlines, po-lygonal and then circular by creat-ing frame grids along the lines at equal spacing. This achieved dif-ferent results as the line segments were considered separate and so lofted surfaces individually. Also the circular sur-face twisted the orientation of suc-cessive curves at points along the

Starting with a sim-ple branch that splits into 2 lines at every vertex and model-ling for that.

EXTRUSION MODEL

Starting with a twisted box for interesting geometry then mapping boxes to that surface. Then creating a curve faces from the intersection of those box surfaces from an offset surface which radiates at 45 0 from center. Extruding those surfaces back to make them solid surfaces again leaves an interesting result of the starting twisted box.

LOFT CONTOURING (AEON EGG)

Some of the surfaces generated were not finishes leaving large patches in the bake that were empty

FRACTAL GEOMETRY

Scaling the geometry down at its ver-tices and using Boolean tool to cut it away creates the repeating shapes.

ATTRACTOR POINTS

Starting with a point grid with a central attractor point generating polygons .Then moving that point to the corner to vary the effect and extruding that result.

The same definition but done with a circular base and attractor point at a point on another circle

Wire Meanings:

Solid Line = Single Data

Double Line = List of Data

Dashed Line = Multiple Lists of Data

DATA LISTS

Data Operations:

Principal: = Recently added, maintains the input path of the data

Reverse: = Reverses order of data in a list

Flatten = “flattens” the data into a singe list

Graft: = Creates individual lists for each piece of data or group of lists

Simplify: = Will simplify the lists of multiple data branches, for instance from {0,0,0} to just {0}

Re parametrize: = Reworks the data into its propor-tionate value between 0 and 1

Single numeric data such as point locations, sliders, number inputs etc

Represents more than one piece of data. Can be shown with panels to see the lists and format of the data

Similar to the double line but multiple lists of data within the operation
