Animation x 3

The following animations are created by 3Ds Max,
and they are all contained the method of "pan", "move" and "rotation" in one.

Original Cactus Model:


X Model:


Y Model:

Y model - cut off 70% from cactus model

The image above shows that the volume of Y model is 22519.2,
which nearly the 30% of the volume of cactus model.

Proposal:
This model is created basing on the concept of "freestanding exploder"
which its porosity is greater during the explosion in exp1.

As I mentioned in pervious post,
according to the result of exp1,
the fractional pieces of the "freestanding exploder" was going off into different directions and the sizes are various.

Therefore, I cut off the void ramdomly through the entire model by using irrectaular and incisive shapes,
once again, I want to create the scene of explosion, as well as expressing the greater porosity and high level of percussion of explosion.

Here are some images of Y model that I rendered in 3Ds Max:

X Model - cut off 45% of Cactus Model

The image above shows that the volume of X model is 41345.90,
which nearly the 55% of the volume of cactus model.

Proposal:
This model is created basing on the concept of "exploder placing in container"
which its porosity is lower during the explosion in exp1.

As I mentioned before, according to the result of exp1,
the fractional pieces of the container exploder was popping up first, then explode.

Therefore, the exterior of this X model is unbroken,
and I only cut off the void in the center part, mainly focus on the top.
I use the irrectgular shapes to sketch the void,
that is because the exploded fractional pieces are irrectgular,
I want to create the scene of "explosion"

Here are some images of the X model that I rendered in 3Ds Max.

Exp 2 draft proposal

In exp 1, I created a comparison documentary movie about explosion,
which experimenting the different porosity of fractional pieces if the exploders were placing in different method - freestanding and within a container.

The result of Exp1:
1. the fractional pieces of the freestanding exploder was going off into different directions after exploded, which mean its porosity is very high;
2. in turn, the other group of exploder was placing in a container, its fractional pieces was popping up first, and then explode during the explosion; comparing to the freestanding exploder set, its porosity is lower.

In exp 2, I am going to create 2 models by cutting off the specific volume (X = 45%, Y = 70%)from cactus model, to express the result that gained from exp1.

Since the percentage of X is lower, so I would apply this prescription on the container exploder , as its porosity is lower. On the hand, Y percentage will be applied on the freestanding exploder, in order to express its greater porosity.

Calculation task

The image above is showing one of the solid work function - mass properties volume,
which can calculate the actual volume, density, mass, and surface area of the model.

The volume of this Cactus model is 75265.08 cubic meters.

In the next process, I am going to draw the other X and Y models basing on this cactus model,
with cutting off a specific percentage of the volume which is 45% and 70%;
moreover, these 2 models should express and related to the porosity and explosion concept that I found in the Exp 1.

Before building up the model, calculation is the first step:

X model : cut off 45% of the cactus model volume (75265.08 cubic meters)

75265.08 x 45%

= 33869.286

I should cut off 33879.286cubic meters from cactus model.
in the other words, total volume of X model should be 41395.794 cubic meters,


Y model : cut off 70% of the cactus model volume (75265.08 cubic meters)

75265.08 x 70%
= 52685.556

I should cut off 52685.556 cubic meters from cactus model.
in the other words, total volume of X model should be 22579.524 cubic meters,


Through this mass properties function,
I can get the calculation done easily,
and also a huge benefit for calculating the requirement of surface and construction material for the particular model.

Cactus Model

These are the image of the 363 George st cactus model that I created in solid work.
I used lot of plans to create the voids according the their different height,
Firstly, I sketched the shape of the void on the plan,
then using the extrude cut function, set up the correct height and direction,
after all the voids were created.

To create this kind of architecture 3D model,
I think solid work is much more easy to control comparing to 3Ds Max,
because it is accurate and efficient which can draw the shape through the section and plan.

363 George Street Envelope

This is the first step of creating the cactus model of 363 George st,
this envelope model is built by solid work,
through the "sketch", "plan", and "extrude cut" function.

In the next step,
I will simply use these three functions to cut the void,
in order to create the cactus model for the future tasks.
