modelling assignment

hmmmmm....off the top of my head ...

 

For the shape I'd probably start with a geosphere.....delete faces where holes needed......add shell modifier for depth....

Texturing looks like it'd be a nightmare though...I think you'd need to unwrap it ,texture paint it and create a bump map to give the basket weave effect some appearance of depth...

If no one else does it I might give it a go tonight when I get back from flying toy R/C airplanes :D

It's a soccer ball with the pentagons removed. I'm an American, so I don't hav an actual soccer ball to work with. The complication is the weaving of the parts, so get a soccer ball and wrap it with string to figure out the geometry of the wrapping then... model it. I recommend working parametrically. Yeah, that's it, parametrics. :)

does anyone know of cad application for exploring 3d weaves?

 

I would like to explore basketweaving in CAD - I have no experience making baskets - and I am looking for a way to explore the 3d quality of warps and wefts and not cimply apply texture to a flat surface...

 

any advice is appreciated.

Well, you could start off with a hedra, with Family selected as Dodeca/Icosa and family parameters of P = 0.4 or slightly more.. maybe .45... Also, vertices at Center and sides for subdivision later..

well you get the basic shape..

 

and ah..well.. it gets messy from here onwards.. select the pentagon shapes and delete.. and then go on and divide the edges (only those edges that do not touch the pentagons) so that you get parallel strips of polygons running around... (like a ribbon strip going around a football...).. .

 

Very messy.. and then the modeling to show the intertwining parts..hmm .. you need to be a masochist to go through all that pain :D...

 

Okie.... let me see if I can get something done.. Do you need it urgently? the method or the model, what takes priority... I mean I can try and model it.. but explaining how I made it isnt likely to be easy for me :D

thanx for trying to help

i am more interested in method of modelling

u could easily do timelapse images to explain me or u could send me the file with the different models explaining the stages

Hi... sorry about the delay.. I am not used to screen capturing software.. took a while to figure it out..

This is a small demo.. just to show how the object can be modeled.. this isnt perfect and I wont claim that I am some kind of guru in 3ds.. but :D here goes.. http://rapidshare.de/files/32566475/hdDEMO.rar.html

 

umm.. yeah this isnt the best way of doing it.. will see if I can do better.. if you want the grooves and the bumps modeled too, then er.. that will be really asking for a lot.. but could be done..

:D alrighty.. go thru the video and tell me..

 

The rest of the GURUS here.. please forgive me if I am doing it all wrong.. or if it isnt the best way to do it.. I just tried it my way..

 

EDIT: I am trying to do it with tubes.. will see if this is a better method

Saw the video - good work. I wouldn't worry about the grooves - do a bit of UV mapping then get your renderer to do it in displacement. Question - I don't use patches very much, is there a simple way to bridge edges to complete the weaving? So that if you saw through a hole to the inside you'd see the inside of the weave?

Thanks mate.. yes I dont use patches much either.. but this was a nifty way of doing it or so I thought.. But I see what you mean about bridging the patches .. well there is another way of doing this.. call it the complicated Runge-Kutta-Jacobian convolution theorem (Just kidding, LOL).. actually using 6 tubes with minimal thickness and positioning two tubes at 30 degrees to each other and then adjusting these pairs to form a football sort of shape and then deleting the polyfaces that overlap or pass beneath the .. never mind.. will post screen cap stills.. to show what I mean..

Ok.. hi.. the zip files contain a haphazard sequence of pics I just made to show what I couldnt explain very well..

 

I made a tube.. rotated it at 30 degs.. I set the Pivot "center to Object" ... then cloned it at 60 deg .. then cloned the pair and rotated it (notice the "O" rotated to form a "wide X" in the left viewport.. well something like that.. )... then cloned that pair again.. and then rotated the new pair.. sheesh.. it is bloody confusing..

Now just click on the individual Tubes and send it to Origin (Remember, center to object pivot).... well we finally get an approximate football shape.. not really.. coz the pentagons dont really line up.. maybe the degrees need to be different from 30.. dont know.. didnt calculate,..,

alrighty.. now use poly modeling or whatever to edit the faces and the deletion/bridging or whatever needs to be done..

WHEW!!! I am tired of this.. mods, pleas ban threads like these :D

Sorry about that.. just get into a nasty mood sometimes.. :D..

Need any help with the PC? what problems did you have? (er.. after all, as a former geek Software-Architect-:-Jack-of-All-:-Damned-Nuisance, I guess I am entitled to butt in and ask you what problems you had with the comp LOL)..

**Sigh**... this is going to take a long time.. ok.. short attempt first. If you have added any new hardware try removing it and restarting.. If you had a power outage, SMPS problem or power surge or hard disk problems and if the hardware isnt already bloody fried, then try this.. >>>

When your computer starts and the initial boot screen starts.. hit F8 several times.. If you are in luck and your drive content has not been damaged in any way, you will see the boot options screen.. choose "Last known good configuration" ... see if this helps.. if you dont get the screen or if this option doesnt help, then you need a lot more help than you think.. Also, if you do get the boot options screen you can also try "Safe mode" as an option.. (It will probably halt at SOMETHING.sys and hang there for a long time).. If all this fails, you can insert the windows isntallation CD and reinstall without changing the exisitng system (upgrade install.. even if it is the same bloody system, you get to call it upgrade install - in reality, all it does is replace corrupted or missing files from your windows)... alrighty, if all this doesnt work, flame me.. and ask me for better explanations LOL

Sorry.. one cardinal mistake.. I didnt ask you what changes you made (if any) to the PC before this problem started.. did you add any hardware? change any graphics drivers? or anything happened to the bios etc..

Also, if you have any new PCI cards added (LAN, Sound etc), remove them, especially LAN cards / USB devices .. then try booting..

 

EDIT: Go to BIOS and reset to bios defaults.. if this was a USB problem it would resolve it.,
