Week 05 Day 31, 11th July '11 (Mon)

Felt I had progressed well last week especially on Friday, a lot was done and couldn't take my mind off the project even on weekends. Can't wait to get back to SESI and dive back into it!

I updated some weekend renders back in Day 28 - check them out here if you missed them,

LOS Attribute Transfer test
http://www.vimeo.com/26309952


Attribute transfer from LOS fonts to grid to form extrusion.

This one was a flipbook from earlier R&D on embossed text,
followed Khermah's attribute youtube video. The method has the potential of achieving what i want but will leave my options open for now as there's time for further tests.

Please don't hesitate to comment or critic any of my work, do it via this blog or email me at zhengjiabao@hotmail.com (Anybody)!




Setting up a mask using attributes
Last Thursday during the review, Steven said I could create another custom attribute and treat it as some sort of mask (like Photoshop) to control a portion of the extrusion for embossed texts. Reason is i may want to animate the text extrude up after a hammer smashes down to show interaction.

Didn't get what he meant but was nice he actually demonstrated it on the .hip file.
Here's screen-captures to illustrated what all this is about, look at different values.

























Server down in the morning
Now back to Monday's agenda, came in and the server (containing latest project archive) was down due to power outage over the weekend. Aliza and the a couple of interns were working on it, meanwhile i had to update my blog (here).

Server came online and i went back to the hammer model.



Layout UVs of Hammer Head
Watched a UV tutorial on organic models last weeks, kind of forgotten how it was done... had to refresh my memory by watching again briefly.

It wasn't that a tough job but just like doing UVs anywhere, its time consuming and requires the person to a little meticulous. Got the job done, saved the UVs as a texture image and brought it over to Photoshop.

01 - UV Project, orthographic mode and we're using "Vertices" and not "Points because we're working with UVs now.













02 - UV Pelt, this node is use to slice up each side and allows you to group them. It requires 2 things to execute, specifying the edge loop and 1 primitive face within that loop.












03 - After pelting each side of the model, we have to stitch them back together and this is done using UV Fuse.

You need to align each side close to each other and select the edge shared by them, using UV Fuse, you can join the points - I used the point distance threshold to do it but the vertices have to be accurately placed.









 04 - Like other 3D packages, when you work perform UV layouts - at the very end, they need to stay with the 1 unit by 1 unit UV space before exporting the image to a painting software.
Using UV Transform node, i positioned them neatly.











05 - Will be using a displacement map at a later stage so i may have to add more divisions to the hammer, because my UV were done in the proper order - I could increase the divisions (with Subdivide node) after the chain of UV nodes without destroying it.

Look at images below,
Low-poly











High-poly















 
Random noise to break up perfect corners
There will be extreme close up shots of the hammer head and didn't want people to see how perfectly modeled it was, there should be dents, wear & tear on the hammer so i altered the point positions using noise within VOPSOP.

Came across a couple of pretty interesting webpages while scanning forums, thought it would be nice to share it here, hope you like them.
