CONTENT The aim of the portfolio is to explore and showcase the digital workflow through various softwares. Most of the projects are conceptual and is inspired by nature. Projects are chosen in such a way that I can explore and experiment with differents tools and techniques. The following pages showcases the project’s process and the final output.

01. Biomorphic Design Introduction

The basic development of the models starts with replicating the rock structure on the exterior surface and building a structural system inspired by flower. In the project same data(curves) has been edited and used multiple times to achieve different components of the building which helped me to understand and develop the scripts logic.The model has component like truss frame work system, roof, facade which enabled me to use grasshopper script extensively and find efficeint workflow.

Learnings - Converting simple 2d drawing into complex 3d model in grasshopper - Commands which bridges curves and creation of surface - To handle lengthy scripts and manage them.

- Functions of brep,surface, mesh and how to modify them.

Process

01 Creating column centre line and the referenceframes of the column in Rhino

02 Creating solid mesh through sweep 1 and loft command in Grasshopper

03 Exploding the column in surface in order to create lattice 2d curves on it

04 Repeated the same process to each column and applied pipe to the 2D Lattice curves and sphere to the junction of it.

05 To create the side roof and purlin, centre line is created on every columns top surface.

06 To create purlins on the roof the centre lines(03) are segmented and in between lines are created.Further sweeped with square curve

07 Two lines were created at start - end of the centre line(05), and sweep command is used to create a surface and offset with the distance of purlin size to avoid collision.

08 Inorder to divide roof surface into 2 parts(glass - solid) surface split is used.

09 By surface offset, surface is divided and extruded resulting in to the border of the roof and glass.

10 The roof side lines are connected with facade line which can along the line and verticle frames are made

Rock Structure | 01

Roof and borders 11 With same process front side column truss and roof is created.

12 To create the facade, centre line is create on the columns outer surface and surface is created.

13 To create a organic design of facade, facade surface is unrolled on XY plane using u,v dimension

Glass panels and borders 14 Random points were placed on the planar surface and pattern is created with the help of voroni

15 Straight curves are transformed into smooth curves and scaled it down

16 Further, the facade curves are splited with the surface(15) resulting in facade frame surface and glass panels

17 Then, it is extruded in Z direction to give thickness and it is morphed to the actual facade surface(12)

18 Same process repeated to create rest of the facade panels.

02. Generation of Organic Design Introduction

The idea was to create complex organic geometry in the mesh family, simply by 4 curves. The aim of the particular project was to explore and be familiar with the mesh editing tools/ softwares. In this project, basically there are two geometry, ribs and the mid part which is formed in the grasshopper and then in Houdini sofware, multiple effects have been added to the mesh to achieve the result.

Process

01 Two vertical curves and horizontal curves

02 Tweening vertical curves in between horizontal curve

03 Extending curves in negative direction and creating curves from start - end points

04 Applied offset both side to the newly formed curves

05 Reducing the polyline to create a low polyline and created mesh out of it.

06 Checking the normals of the mesh and sorting the normals, Flipping the normal if its reversed.

07 Smoothing the meshes and extracting the boundary vertices.

08 Extruding the mesh while boundary vertices acting as an anchor points

09 Mirroring the same process downward and reversing the normals

10 displacing the mesh and Lofting the in between part of the two surfaces respectively

Generation of Organic Form | 04

11 Joining 3 mesh and rebuilding the mesh, resulting in set of closed mesh(middle part

12 Jumping back to the oppositley extended curves(03) and applied pipe mesh comman

13 Extenting the polyline ends

14 Loft mesh tool is applied with the help of polygon which are along the polyline

15 Applied twisting parameter to the model (not used in model)

16 Segregating the model into ribs and middle part and exported to the Houdini Sofware

17 Imported middle part model into the Houdini and applied sub-divide, smooth to refine the mesh.

18 Applied remesh for converting into tri-mesh and polyreduce to adjust the polygons(To accelerate the workflow)

19 Checking the normals of the mesh and used connectivity to make sure it is closed mesh

20 Applied vdbfrompolygon to breakdown in to small and vbdreshapedsdf to scale the object.

21 Bounding box is created with reference to model and vdbfrompolygons is applied.

22 Implied volumevop to create cloud type effect in between box(31) and coverted to vdb, resulting in ogranic shape

ART 801: Introduction to 3D Modelling and Parametric Design

Generation of Organic Form | 05

24 Transform is used to resise the shape of newly formed vbd and vbdsdfinterfsect in used to intersect vbd with the vdbfrompolygon model(30)

25 As there are total multiple closed mesh so For loop is excecuted so that same process can run for every mesh to get the desired result(For loop is applied from 30 to 33)

26 Applying smoothing to the model

27 Importing the rib model(24) into houdini and applying vbdfrompolygon, vbdreshapedsdf and vdbsmoothsdf to refine the model.

28 Combining both models(34 and 35) by vdbsdfunion and copying it with parameters to get desired set of array.

29 Again making the copy and trying to give an offset effect to the model and union it.

30 Mirroring the model with vertical axis and adding clipping at the axis line to avoid collision.

31 Same mirror process in done on the horizontal axis and converting into polygons

32 Lastly, rendered in Keyshot and and photoshop.

03. Abstract Sun Introduction

The model development is inspired by the sun and its behaviour which enacts the sun in an abstract form. In order to develop the concept, common characteristics of the sun like heatwave, layers of sun, rotation, particles and the shape is implied. This project is an example of form finding by the help animation, many forms can be explored by tuning some parameters of the forces applied to the model and further can be implimented into architecture.
