WIP Rhino Comp 1 - OamadeusO

[kirisute]

hey nice choice!
i can see a couple of ways of building the blade and the handle......
methinks the skill here will be recreating the level of detail!

[OamadeusO]

I picked it because of the level of detail. Going to force me to work at it.

The only thing i'am not sure of is the grip texture (the bumps on the handle) If I just use hundreds of domes its going to push up the geometrry a lot. See what happens...

[kirisute]

y not create a series of triangular solids that stretch across the handles mesh....set them up then difference them out?
might make a complex mesh as a result but at least it will be one mesh rather than hundred of little ones...

[tilite]

that is a funky blade! Im glad you chose it too, it will be a challenge but your only going to learn from it! and besides your going to have a wicked model when its all over:thumbsup:

that is a really cool knife, it looks like it going to be fun to model... good luck:)

[edt] p.s. i hope you dont mind me editing your post, thought you should put the image in your thread???

[OamadeusO]

All good suggestions, let you know how I get on.

btw no probs on the edit. I'am just used to forums that get real shitty if you link to images from sites you dont own.

[OamadeusO]

Ok here's the first wip screens.
Not started on the blade yet, just done the handle. Pretty happy with it so far.

Had some problems with the fillet around the edge of the body. Solved that by using blend instead.
Got to rework the bottom left revit on the top picure. The inside centre is too high.
Btw not only is this my first Rhino project outside of a Tute but it's my first 3D project!:D
Be kind but any crits welcome

[OamadeusO]

Right... i'am now totaly knackerd, should have been to bed 2 hours ago:scream:

Though I couldnt resist just drawing the curves for the blade... then modeling it.... then adding details....

Hope you like the result, going to bed.

Could use some advice on how to light and texture this thing.

hey, looking great! I'm just wondering how you made the sharp part of the blade

[kirisute]

First 3d project? is this where we stand up and give you a slap! hehehehhe
superb work so far!
the model has just enough detail to keep the eye wandering over its surfaces...and you have reproduced much of the detail superbly!
well done indeed!

[OamadeusO]

hey, looking great! I'm just wondering how you made the sharp part of the blade

Cheers:thumbsup:
The sharp parts of the blade were made in 2 sections by lofting then mirrored for the other side.

Btw not only is this my first Rhino project outside of a Tute but it's my first 3D project!:D


*Spat coke all over keyboard :eek:

it was a very good choice this knife and you have pulled it off great! especially for a first attempt as a 3d model... thats just amazing.

i have a few tips on lighting. First would be to have your properties toolbar open so you can tweak all this jazz. So actual lights.. it looks like the intensity of your light is pure white. You just wnat to dim that and you do that in your properties, just select the light, pull down the tab and select light there. Then to change the intensity use colour. The closer to black it is the darker it is, lol. So you might just want to put your 2 overhead spotlights on maybe 50% white and creat another light looking up onto your model... just to bring out the highlights where it has been completely blacked out with shadow.

So they are just a few quick suggestions... the best way to figure it all out is to just play with it.

[OamadeusO]

Cheers for that. Any tips for getting the engraving on the blade?

looks too complicated for a boolean....

[sevenfingers]

For the engraving (provided the standard boolean tools do not work) I'd project the curves, cut the surfaces and extrude them downward and then join them... a manual boolean.

Keep in mind it's going to eat up humongous amounts of memory though :D

[kirisute]

y not just work it as a BUMP map?

[OamadeusO]

Never done Bump maps before... I know you use a greyscale image to get height and depth but thats about it. any tips?

[kirisute]

hmmm ok here is how i do things....

export your model as an OBJ file.....then use a program like UVMapper (which is free) you can create a texture map for the model.
once you have the texture may you can take that into something like photoshop and create a realistic texture for the objects......
on top of that you can create a BUMP map from the texture you have created....basically..itsa greyscale image.....BLACK is the lowest depth..WHITE is the highest...
the easiest way to create the engraving with a bump map would be to recreate the logo...then make it a black silhouette on the blades texture.......that would create a nice BUMP of the logo for you as an engraving.....

i dont know if you will find alot of people using BUMP mapping in Rhino.....but if you search the net for BUMP mapping hints and tips within Poser or Bryce you will soon get the ideaof how things are done!

[OamadeusO]

Cheers for that i'll check it out.
However It's not much help for me in this comp because we have to stay in
Rhino for the project...

[kirisute]

methinks there is nothing wrong with taking the object out of rhino to create a texture map and BUMP map....then just applying the texture map and bump to the object in Rhino to render....

[Taria]

Not to take sides or to suck up to kirisute, but he's right. bumps are wicked to work with if you get them right, it takes practice. I do know how to do those, now I feel foolish. :(

but he's right, there's no problem with takeing it out of Rhino and doing a map for it, then you can take it into any paint program and do a nice texture and turn that texture into a bump and save both of them, then apply and you get a nice effect, I love useing bumps as much as I can when they are needed and I find they are needed for everything, everything I say! you must use bumps...look into my eye's, you must use bumps...he he he

okay, enough of that.. this is pretty good for a first time. Your alot better then I was my first time using RHino and yes I made a sword my first time and it doesn't look any where near as good as this. I'm impressed. :)

[kirisute]

suck up to me? OOOO does she sir? ooooo suits you sir! :twisted:

[tilite]

All modeling and rendering must be complete in Rhino - you will need to submit wireframes to prove this. (this means no external programs to be used - period! Look, we now have a level playng field)

oops... i think i accidently copy/pasted something from the rules thread:shrug:. how clumbsy of me



bumps are great but this is the first competition and things are trying to be kept to basics to keep envolvement high. In the future these competitions will allow your to roam the pipeline however you see fit.

[andrewjohn81]

I just noticed a couple differences in the model and thought I'd point them out.

The fillet on the back isn't the same. The one in the orig image has a variable fillet. You can accomplish that with the variable blend tool fairly easily on that model.

This one could be meshing, but where the blade begins to be sharp on your model looks like it eases into it a bit slower. The one in the image has a very steep angle there. Maybe your blade isn't as thick? The funky shadow at the bottom suggests to me that it's a meshing problemthough.

Reguarding the engraving issue: If you are practicing making models for production then there are two methods. One, you would give the art to an engraving machine in some cases. That would just be 2d artwork. The other would be to actually have that modeled. You wouldn't model that in this case, but in similar cases on other objects you would. That sometimes keeps costs down in the long run as well since it's less processes. Boolean would work, but you have to keep the geometry very clean. It also works best with solids, so keep that in mind if you choose to use that method.

If this is just for renderings then yes, find a way to do a bump map. Something like that really wouldn't be candidate for much else unless you are planning on taking the camera through the engraving as if it were some sort of canyon or something. Even then you may be able to get away with displacement maps.

Really a great go at it. I'm hoping to see the textured version also eventually.

[OamadeusO]

Thank for the comments, i'll take a look at the blade.

Sorry theres been no devlopments with mine for a while, been very busy and trying to track down a free rendering program to finish the project has been a nightmare.

Think i'll fall back on my free copy Cinema v6 I got of a front of a magazine ages ago.

I'll post the mag and issue number when I get home so people can order back issues to get it.
Well worth it, even just for rendering IMHO.

[edir] Ok it's on the cover disc for 3Dworld #43
Cinema 4D Ce release 6 mac & pc versions.

Cant find a link for ordering backissues, but might be worth phoning them...
