Can anybody tell me a good technique to model and texture the back of this chair? You may notice that there are woven bamboo strips on the back rest. I am done with the rest but haveing trouble getting through the back rest part. Please anyone!!

here is the link to the image:

Thats a pretty tiny pic.

Looks like you could just use a box and bevel out the middle to make the "frame" for the back rest. Then just use a plane with the bamboo texture with an alpha map for the middle of the back rest.

Hope that helps.

Thanks for the tip, but i am really new in modeling and texturing. I am haveing problem finding the alpha mapping. And not so sure how it works. Maybe you can explain a litte about if for me..

Thanks for your reply!!

The alpha map is a texture that will represent the see through parts of the texture. In your case it would be the holes in your bamboo texture. Some times these textures are saved out as a .png or .tga with transparency turned on, or they are a set of jpg images. One of the .jpg images has your bamboo texture in it and the other would be a black and white image. White representing the area of your image you want to see (the bamboo parts) and black representing the areas you want to see through. (the holes)

Here is a tutorial I found on Google over at DA: http://darkaurasoulstealer.deviantart.com/art/Alpha-Map-Tutorial-79602962

Im not sure what program you are using but he his showing it out of studio max.

Hope this helps a bit more.

You are welcome! Good luck with that chair.

Hello again!! I have tried modeling wooden panel and failed terribly.

What I started doing was making outlines with spline.
And then connect them together. It all went ok...
after that I used extrude modifier to get the depth.
It was ok. Then I tried to chamfer the edges.
It turned in to a mess.
I am sure the vetexes and the edges didn't quite aligne properly.

How would you model the wooden panel behind the chair? What other ways would you have done it?

The chair truned up nicely. But it still needs correction in photoshop. But i am sure i couldn't have done it with out your help.

Thanks kindly

Alrighty sounds like you were on the right track. I did a quick mockup. (Still assuming you are using 3D Studio Max)

1. Break that thing down to the most basic shape.

2. Extrude and add a edit poly then chamfer your edges. I added a 3" extrude on mine with an 1" chamfer on my edges

3. copy and paste the shape to build out your wall.

4. group the objects and add a edit poly on that. then go in and clean up objects to end your wall.

Hope that helps.

Wonderfully done!! And you make it with simplicity too!!

What I did similarly, was the spline. But I tried to make out the whole shape, using spline boolean to union and subtracting the shapes. I ended up extruding unwanted faces at the end.

This helps alot!! And yes!! 3ds Max.

I never tried Maya. Whice is better in your opinion? I sometime hear people say Max is better at interior and architectural visualization. And Maya on the other hand is better at animation. Well, I don't know.

Thanks again!!

lol.. Whats better is whatever you are most comfortable using. Right now I would say studio max over Maya because I have used Maya only a handfull of times. 5 years ago I would have said Lightwave because that was my main program for work at the time.

Good Luck with your scene!

Hi, I just finish rendering one of the scence I am working.
And because you are more experienced with the program.
I would really like you to give comments on it... critiques, tips, and etc..

That way I can improve and develop my 3d skills.

Thanks again!!

Looking nice. Maybe cut back the glossiness on the door frame and closed door a bit. Also the drape can use a bit more geometry, it looks stiff right where it bends. Maybe just make it drop straight to the floor instead of flaring back out.

Sorry if you weren't looking for crits, just a couple things that stand out. It is coming together rather nicely though!

No, thats exactly what I needed, someone to help by showing the flaws in the picture.

- the drape should have more geometry, or simply let loose to the floor
- adjust the door abit
- cut the reflections on the tiles

Got it!! Every bits of your suggestion counts here !!!

But one more thing, I have been trying to model a folded cloth, a towel, and a table cloth (a napkin that is just let loose on the table) I tried by using spline, then extrude modifier. The result is terrible. I am having alot of trouble modeling curve or smooth model.

http://picasaweb.google.com/lh/photo/zE2Mv2ZqN3wzMzw-P23enQ?authkey=Gv1sRgCKHxmOmA3o6iJQ&feat=directlink

How can I make it smooth, the edges? Make it look fluffy, not so hard surface?

The turbo smooth modifier can help out with soft objects like cloth. Made a quick tutorial for the towel.

First I did a quick Google on how these things look when they are folded up nicely. Looks like they fold one end up towards the middle and the other end goes up over that.

http://kcindraw.com/help/towel/towel-tut01.jpg

I started with a box with the parameters shown.

http://kcindraw.com/help/towel/towel-tut02.jpg

Added some extra edges down the middle so I can fold it in half.

http://kcindraw.com/help/towel/towel-tut03.jpg

Folded the object in half and cleaned up the side to look nice.

http://kcindraw.com/help/towel/towel-tut04.jpg

Added more edges here to make another fold.

http://kcindraw.com/help/towel/towel-tut05.jpg

Folded this geometry over and arranged the edges.

(Guess there are too many images...)

Adding more edges here for this last fold.

http://kcindraw.com/help/towel/towel-tut07.jpg

Fold and arrange the edges again.

http://kcindraw.com/help/towel/towel-tut08.jpg

Add some more edge loops, so when we add the turbosmooth modifier the object will retain its shape better.

http://kcindraw.com/help/towel/towel-tut09.jpg

Adding in details such as the puff out middle part and more edge loops to help maintain the shape.

http://kcindraw.com/help/towel/towel-tut10.jpg

Add the turbosmooth modifier.

Hope that helps out. There is also an interesting tutorial over here using the cloth modifier.

No worries.. not trying to show him how to build the perfect towel. Just showing him one out of a billion different ways to make one.

Course you could add some fur to that towel to spice things up. ;)
