Nice one Chris. Good time to use tsAppend :tsAppend: . This is the type of thing that many beginner users think should be a push-button in T-Splines. I guess it is relatively straightforward but you need to lay out your faces the right way. Good work.

I initially used tspipe for almost everything, simply because it was easier, but you are correct... tsappend used correctly is far more powerful, better control over fine areas..

My next TS project! New body shell in foam for my Drone. will fibreline the shell after. adding some mechanical fitting areas for GoPro HD cam etc.. This job is screaming for TSplines ! :)

the existing outside shell is like so



sketched out a few ideas will model next week.. happily it just just just fits on my cnc..

Postby Chris Botha » Thu Jan 12, 2012 4:30 pm

eap, can hold around 110gr.. so need to dump the external fixturing system and add a locating thread instead... quite a fe wof them around but all work on adding more weight to existing frame, I plan to reduce weight of frame, increase strength and leave more room for the 2600MAH (orig = 1000mah) battery AND the Go Pro.. at current its not possible to have both and orioginal battery only = 10 minutes flight time.. so i want to make a construct that i can build a "skeleton" around, fibleglass, carbon fibre the construct and add mounting points..

the AR Drone 2 apparently features GPS tracking too.. I wont buy one tho.. it was hard enough convincing the wife that this was legitimate research...

also you need to be carefull because you can kiss your drone (300 bucks) and camera (300bucks) goodbye quite easily in the wind.. so think extra weight will actualy help handling, less nimble but more stability..

so this doenst happen ;)

Yeah, I think that the extra weight will help stability. And will make video much more steady.

lol, it seems that you have always the right tool for each job. "Stuff to take things down of a tree"

this is kind of advertising, so delete if you need to, but I figure I have given enough here to get away with a teensy bit of promotion.

my wife runsa seperate CAD entity business to mine doing Virtual Inventory, basically send her some pics she models jewelery, renders stills and/or turntables, one of our clients is live at the moment, and some pieces feature Tsplines models, feel free to browse around and if you think you could use something like this contact my wife at

caro@digital-jeweller.com

HA! that webinar has come back to bite me on the bum! The transcript had a bunch of my lunatic fanbase asking ridiculous questions like "Is he the Green Lantern...."

last night quite by coincidence my kids watch the movie and HAD to have a ring.. this recording of that ;)

[BROKEN VIDEO LINK: Re-Uploading this weekend]

lets hope the rumours dont start up again about my super hero secret identity ;)

FYI.. I tried this in Tspline but I am quite obviously not talented enouhg to get it right, i tried from a quadball, extruded the "beams" and tried to insert edges and tighten up the weights.. but .. well .. no go.. some stuff its jsut easier to do the good old way..

BUT..

@Juan.. dont let that stop you proving me wrong!?!?!?!?

HI Chris: Thanks for the tutorial. Quick question. When you refer to F4 what do you mean? Have you applied a macro to F4? or What? (my fault of course, I must be missing something).

Hi Chris,
I never normally post anywhere, but I really wanted to thank you for your posting habits! You have helped me learn an enormous amount in the last year.. muchos gracias Mr B!
(A year after buying tsplines I've got my little training day on wed.. :roll: )

btw, did you ever get along with blender at all? I'm trying to find a solution to learn to model 'sculpted' forms (like a skull or a proper bumble bee or something - you know, like old fashioned clay models) and it's appealing that it is free..

Thanks again..
Gia.

Hi Gia,

Your kind words appreciated :)

Blender is like Zbrush.. powerful, but you need to be "special" to understand its interface.. if you have some money laying around spare I HIGHLY recommend MODO, or if it s budget concern try Silo, Glen Southern has heaps of tutorials for Silo which translate very well for tSplines as well.

no worries, I should use zbrush to do the hair and final trims etc, but this a production model, not a render model, and realisticaly my milling machine cutter wont mill that super fine detail <50um, so some stuff like that i just do by hand in the wax, or in the final piece.

Sculpting is SO not my thing.. but i did find after a half hour, engraving and driving a tablet pen are actually distant cousins, I "could" develop the skill i suppose, but I don't have clients for this outlandish type of stuff..

anyways..

90% of the base is all tslines models from the Matrix library, slapped together with SPLOP over a drape.

projected a curve, some gems and beads then off to 3dcoat..

no special settings, just import, pick up pen and GO..

all up i estimate 40 to 45 minutes work.. but dont quote me, I was trying to record and kept crashing rhino so would need to restart recording.. eventually gave up.. If i do another i will setup as tripod.. 3dcoat EATS ram..

The BIGGEST advantage to doing this in 3dCoat imo so far has been that you dont constantly need to remesh the damn thing.. voxels truly are a completely different beast, chalk and cheese to emulated voxels that other sculpting apps I have tried offer.. but you pay for it in CPU cycles..

I was going for "Crown and Brains" but my brains look a tad very Acanthus scroll.. wonder which recent skill I learned that I stole that from..



anyway.. the model will go onto GrabCad later ;)

I am finding the blend of Tsplines and 3DCoat to very good! you can spend an extra hour trying to tweak a fine detail but if you treat your model as clay parts, and simply slap on parts as needed then take to 3DCoat to blend it all up is a fast satisfying result..

Wouoooh... As usual.

I hesitated last year between 3dCoat and Topogun. I took Topogun because of the price, but when I see what you can do with 3dCoat, :cry: :cry:
Do you think I can get the same result with Sculptris, which is free ?

And just a question, please : when I see some of your videos, and screenshots, I'm thinking you work directly on a single mesh, and " distort " it. But in the 4'15" video, you select differents elements... But as I don't speak very good english, maybe I misunderstood something you wrote before... For example, I don't understand : "slapped together with SPLOP over a drape.", neither : " voxels truly are a completely different beast, chalk and cheese to emulated voxels". I beg your pardon, would you mind to get deeper in the details ?

I wanna be your little Padawan.

Hey Oliviertjie..

I had no idea what voxels were either when i fist played with 3dcoat.. but the beauty of it is that you dont need to understand.. in the same fashion as you dont need to understand how a microwave works to heat up your sandwich.. 3dcoat can flip between voxels and polygons instantly which is the secret to its true power i feel.. you can use tools from both mindsets in the same application.. autoretopo the massive mesh back down to usable size , reimport to rhino and voila job done..

You can select seperate parts because it has layers. the fast way of seperating all your goodies onto layers is to import everything as one obj, then tick "import without voxellising", it willseperate all the meshes onto a layer each, once that is in, simply click the [S] in the voxtree to turn it into a [V] and merge the items in the tree you want joined

essential voxel are like little grains of sand, so the model cant have problems like exploding polygons, tears etc. Really jsut means clumsy oafs liek me can use it without breaking stuff. The major drawcard for me is that its interface is sane.. it looks and feels like every other normal program I own, unlike Zbrush which after three years am still no closer to figuring out.. I am glad that some people have years to try unscramble the spaghetti bowl tool system.. I however need to make money and feed my kids..

I dont sculpt directly from 3dcoat, i port my meshes, polys etc to 3dcoat then use it as a putty knife to make it all play together. rhino/tsplines is still a faster workflow to bend/warp/shift/twist the base item, then take it yuor sculpting app.. use a screwdriver to tighten screws and a hammer to hammer nails.. If i get some time I will do a clip dude.

Thanks Chris.

dont buy anything on my say so dude.. think, listen, learn, get a demo, play around with it.. what works for me may not work for you?

software is quite individual to the user and his/her own implementation of it.

i recorded a clip of porting this tspline+pipe+box nurbs to 3dcoat and then apply two decals from hieghtfields and some mesh reduction smoothing and working with layers.

its uploading, be patient.

video will be live in say 20 minutes here



hope this helps dude.

:shock:

You use 3dCoat as if you created this soft... It's amazing, even if speaking english must help a little bit. You gave my name to a file, I'm proud !
Thank you for your explications ! I didn't think 3dcoat can offer so much possibilties...

To be honest I have not even begun to scratch the surface of what it can do.. I needed only a very few of the tools and based on those tools alone it has paid for itself already...

interesting examination on the retopo tool in 3dcoat. i use all the defaults, jsut "next next next through the dialogs and for an automatice tool it works quite well on some models!

Render

Tspline toplogy on the seperate parts

into 3dcoat for merge/retopo
Image

and back to rhino for comparison.
Image

notice it pops triangles into it, but the flow where one part merges into another is simply awesome for wizard driven retopology tool!:?!

you can grab the original exported retopomesh a=on my grabcad, its stl format but untouched otherwise, will convert back to tsplines happily.

Thanks Chris !

The time you spend doing something is probably shortest than the time I spend chosing a name for a file...
