mcjTransport, model/animate spline based tubes - Version 1 is out !!

edited September 2012 in Freebies

Download page and manual --> https://sites.google.com/site/mcasualsdazscripts2/mcjtransport

using this script you'll be able to create curvy tubes in 3d space, right here in Daz Studio

the method is similar to mcjRibbons https://sites.google.com/site/mcasualsdazscripts/mcjribbons

( which, by the way, lets you model an infinity of things )

but makes use of something called "parallel transport" described here http://en.wikipedia.org/wiki/Parallel_transport

you'll be able to create and adjust "control points"

based on those points, the smooth tube will be created by the script ( this takes only 1 or 2 second )

    possibly tomorrow !

    but if you read this tomorrow, then it's possibly today

    it could be yesterday!

    ok lets say, possibly saturday september 8th

    maybe 1day later if it's for the good cause of increased ease of use :)

    Wow - that is damned impressive!

    By the way, your Jump script is brilliant in DS4.5 when a Geometry Shell is created for a prop the shell has (for me, thus far) appeared offset from the original item - a quick firing up of your script sorts it all out :)

    Thanks for replying. I think we can all manage to wait a little while longer. I really like the 60s telephone cable, that would be a nightmare to model properly.

    well i updated the hpatch/hblock figures ( https://sites.google.com/site/mcasualsdazscripts2/hpatchc-and-hblockc ) so, the tube maker thingie isnt ready .. but, yeah the s word . . . soon :)

    well today too i didnt have much time to put on the tube thing

    though i did advance a bit

    still there's a 'flippin angle" issue to fix

    i'd say it will be ready this week :)

    the silver lining is, i get to make new images that will decorate the web-page for this script

    the moment i fix the kink ( seems to be a problem with angles near 180° ) ... i think i'll publish the script as-is.

    later i'll see if this can be used to make trees

    gigantic render :)

    A very big render, but IE9 doesn't give me any scroll bars, so I can't see it all. At least the forum software can handle large images now.

    Good news. Ther is no "flippin angle" issue to fix, the script was just doing what it was told.

    so, in the image below, you can see how it works.

    using a script named mcjZeroTubeMaker, i created a 6 sides by 64 segments tube
    that tube is initially so deflated that it's invisible ( hence the name zeroTube )
    on the ground, i placed a photo of a real-life paperclip (a textured primitive plane )
    i switched to the top-view camera
    then i animated the sphere held by Amy (Aiko3)
    the animation starts at frame 0 and ends at frame 64 (since our ZeroTube has 64 segments)
    the red dots on the photo correspond to the animated sphere's keyframes
    at frames 0, 3, 6, 9 ....... 63, 64
    then i executed the mcjTransport script
    and the zeroTube was inflated and bent to become the paperclip !

    hmmm...I've always been partial to green paperclips. This script should be very handy. Thanks for creating it. I can't wait to put it to use.

    REALLY looking forward to this. The script is going to have so many uses.

    Will the script support texturing (UV mapping)? One of the images is showing the checker pattern but that could be a Procedural or a Cycles shader...

    yes there is a UV map,
    shown below is the texturing template for a 5 sides by 64 segments tube

    note that all this is doable (since 2010) using mcjRibbons https://sites.google.com/site/mcasualsdazscripts/mcjribbons

    the difference is that the new script is that you'll just have
    to create the path, and the script will take care of keeping the "tube" non-kinked

    UV maps make me happy :cheese: I remember checking mcjRibbons out when it came out but the "Usage" bit on on the page was (and still kinda is) bit too intimidating to give it a whirl...

    I did somewhat recently "rediscover" your mcjWarp (my old rig couldn't really handle it well enough). It turns out to be really handy for "fitting" dynamic clothing before draping them - especially since you don't need clean looking morphs for that purpose.

    well mcjWarp intimidates me ! :)

    next time i get back to it i may add an UnDo, that's the main missing element to make it less stressful to use :)

    It is KEWL! You could make a whole Brass Section.

    actually i was hoping that you would make the rest of the brass section

    see, one of the advantages of mcjTransport over mcjRibbons, is that the script takes care of making sure the tube doesn't get twisted, which would result in a strangulated tube.

    but mcjRibbons has the advantage that you can specify and modulate the shape of the section of the tube
    whereas mcjTransport, for now, can only make tubes with circular sections

    but maybe i'll devise a mcjTransport-to-mcjRibbons conversion button

    and vice-versa

    still not quite ready

    there's bizarre things happening near the control points

    i compensate by tweaking my control points

    but that's not what we want, we want the control points to be masters of the tubeverse


    --

    if the tube's interior was a pure mirror, i don't think we'd see darkness
    else it would mean that some rays are trapped in the tube, which i doubt is possible


    ... though, after googling it, it's interesting to see that "trapping light" is a very active research field
    and in recent years graphene seems to be a gamechanger

    and read about opalescence

    Absolutely amazing. I can't think of a more general-purpose tool, or one that we have needed for so long.

    as some know, this summer i posted the mcjSuperLathe script, which, among other things, lets you create curves using your mouse

    well mcjTransport will be able to load those curves and use them as the tube profile

    you could use this to make complicated stair handrails

    in the image below, i was making a 300-ohm twin lead for VHF/FM antennas

    You sir are genius, and an incredibly generous genius too *patiently waiting for the script to be released*

    the last touch

    image 2 : you can see the texture can get slightly stretched or compressed,

    that's the last function i'll add to the script

    meaning the release is nigh

    image 3 : (posted 10 minutes later) shows that it works !

    image 1 to do now, fix the UV Map, laterally

    image 4 shows the lateral UV spacing after the fix

    i'd say tomorrow, is the likely release date

    Fig 1 : after fixing the UVs to remove stretching, the script will suggest tiling for 1:1 ratio texturing

    Fig 3 : the script can weld the ends of the tube together
    the texture defect is being investigated as we speak
    oops think i got it, i was trying to stretch a 128 segments tube on a 32 segments path

    fig 4. tube-ends-welding functionality completed
