090926 Tutorial 09

In this tutorial, we were to finish up the previous 3d modelling from last tutorial and to create front and back renders + a slideshow presentation in class.


The original image "reflected arrow" by Jeffrey Smart


Front render with pshop post-editing


Back render without editing

090920 Tutorial 08

In the previous tutorial class, we were required to analyse a Jeffrey Smart piece, collaborate with our peers, reinterpret the image, and represent this image with 3d softwares and rendering tools.

The image the our group pick is called "Reflected Arrows" by Jeffrey Smart in 1974. You can see more of his works from here and here.


Reflected Arrows by Jeffrey Smart in 1974

Here are some of the process works:


Setting up scene


Modeling background building


Modeling puddles


Modeling the circular signs


Preparation of political figures to be mapped on to the signs


Abstracting the human figures in the scene


Material palette in 3D Studio Max


Running trial renders with mental ray

090902 Tutorial 07

We did a little Foster's Swiss Re model today in exploring the lattice structure on the facade using pre-dominating Rhino and 3D Studio Max.

Procedure 01:
Creating 12 Helix from MAX and importing them into Rhino for cleaning up.
Making sure that all lines are individual entity.


Procedure 02:
Surface the Helix curves --> Facet it --> Edit Poly --> Inset --> Separate Steel and Glass into two entities.

090821 Tutorial 5

Tutorial 5 - we learned how to use very very very very very uber basic ArchiCAD (BIM).
The model that we were required to build was Corb's Domino ...



Step 01:
Build Domino in ArchiCAD 12





Step 02:
Exported the model in *.3dm and rendered in Rhino with V-ray then pshop post-editing.



I find that, exporting BIM model to *.3dm will cause the edge to be slightly rounded. The faceted mesh becomes obvious as you can see in the render (become less obvious after fudging the image in pshop). Perhaps *.obj is better?

Hopefully the next tutorial will learn a little bit of rendering technique in ArchiCAD, will that be as good as V-ray? Let's see ......

090821 Tutorial 4

Tutorial 4 - we were taught to do simple animator in max
One thing I find interesting yet a bit meaningless (maybe there are whole heaps of theory behind which I do not know) is to screen capture animation and do lofting in Rhino ... ...

Anyway, here you go~~~

Step 01:
Screen-capturing in max



I fail to do gif animation in photoshop. I couldn't figure out how to export frames into gif image. Maybe there are some softwares on the web which are free to do gif animation.

Step 02:
Trace elements in 2D-CAD and bring the frames into Rhino for Lofting



Urghh ... actually I made a several lofts. I personally think that lofting across linear looks the best. Images upon request.

Animation:
Sent my setup in max to UWA render farm with scanline + skylight + light tracer setting. No external linked material added. It took 3 hours to render.



Some students may split render in render farm. But it DOES NOT WORK for animation. So do not set split render when you send your animation to the render farm. What you will end up with is 16 sets of horizontal-strip-animations, they just do not combine into one.

090821 Tutorial 3

Suddenly feel like putting up all the tutorial exercises ... bare with me :P

Tute 3: 3d-model for Corb's Villa Savoye

Step 01:
Build the whole model in Rhino



Step 02:
Render with V-ray + Photoshop post-editing

090803 Vase Physical Model

Today I finally get my laser cut done and put them together. Gave the vase a flat white spray paint finish for aesthetic purpose.

And, I am happy with it because all pieces join together pretty well =) Although, I spent quite a bit of time on this tutorial, doesn't matter. What's done is done ...

090731 Vase Matrix Using Section

We are to create a matrix using the command "SECTION" in rhino. The sections will then translate into cad format for modification on joints. Then, print the cad drawing to pdf for 2d laser-cut.



Step 01:
- Open vase model in rhino



Step 02:
- From front view, create sections with an incremental angle from bottom to top



Step 03:
- Create vertical sections every 10mm



Step 04:
- The vase might not be able to hold itself esp. the neck
- Created more sections with 5mm increment



Step 05:
- Try creating vertical sections from right viewport



Step 06:
- Create surfaces from planar curve(s)



Step 07:
- Extrude surfaces by 0.5mm on both sides cap on
- Consider using 1mm strawboard, hence such extrusion





Step 08:
- Variation 01





Step 09:
- Variation 02



Step 10:
- Ultimately, orthogonal horizontal and vertical sections from front viewport was chosen
- Create more sections closer to the top to increase structural stability



Step 11
- I think using extrusion and boolean difference will mess up the model by having weird cutout, etc. Therefore, I only use surfaces and the command intersection to create intersection curves on surface for flatten
- After intersecting surfaces, hide vertical elements.
- Lay out horizontal sections with curves across the top view



Step 12:
- Use command "Make2D" and select all visible surfaces
- A set of lines will be created on z=0



Step 13:
- Do the same for the vertical sections



Step 14:
- Remove/hide unwanted elements, leaving only the lines for "export to cad format"



Step 15:
- Create joints (think of how the pieces should be joined together)
- I use clipping system for my vase, i.e. split the vertical sections into half such that they can clip onto the horizontal sections.



Step 16:
- Create PDF(s) for laser-cut

The appointment for laser is on Monday morning 11am. I hope everything goes well without major accident. More images after completion.

090728 Vase Transformer

We have to design a vase for our 1st tutorial exercise. This vase is going to be 3d printed or laser cut on Wednesday 090729. I think my vase is going to be 3d printed. Basically, the vase has a simple design which is lofted with basic geometry.



Step 1
- Draw 2 ellipses, 1 circle, 1 triangle within 50mm x 50mm grid extend



Step 2
- Offset each shapes by 1mm



Step 3
- Select all inner shapes and loft them



Step 4
- Select all outer shapes and loft them



Step 5
- BlendSrf the top of the vase with default blend mode



Step 6
- Draw a CutPlane prepare to create the capacity for the vase
- Trim the inner lofted surface
- Create surfaces for the base by using PlanarSrf



Step 7
- Draw a base plane with PlanarSrf



Step 8
- Apply timber material to the vase
- Apply light grey diffuse colour to the base plane
- Render the vase with V-ray with caustics On
