As I’ve said in the photo forum, had an idea for a cool photo, but it didn’t quite work out, but as said there it got me thinking and lead to two ideas... What if this idea was transposed from the real world to a virtual environment using similar construction and photographic style techniques?
What else could be used to make shapes so artists and photographers can play with light? Mostly without spending too much money, in fact most of the stuff used here came from pound-stores :)
To make it easier to follow, I’ve spilt the two ideas into 2 separate threads. The 3d in here and the photo stuff in the photo forum. Link to that is above

For the 3d side initially I’d like to create something like the effects shown here. But I’m also looking to take it a little further and try to create a freebie .PDF with loads of tips; ideas etc and share that with everyone. Figure doing will help other artists, which after all is what community is all about. By that I mean stuff like materials settings which to make the shapes glow or emit light. Or maybe what other kind of other scene lighting or lighting effects might needed. IBL/IDL etc. Not just for poser, but vue, studio etc.

To help kickstart this, and so there’s something anyone can get and use for free, I’ve made a simple 3d model of an art gallery wall and some shapes (all in poser prop format). The gallery model is mapped so you can easily replace any picture on that you choose to. The shapes are also deliberately basic in terms of shape and material zones That can be downloaded at the link in this post. Well that’s my idea, now it’s your turn! If you have helpful suggestions please post them here. For the photo side please post in the photo thread (link to follow).

     Extrude some tubing in a modeler (Silo is my first choice).

     The main extrusion would be the visible "neon".

     Nested just slightly inside would be an IDL emitter extrusion.  Uncheck visible in camera, and text-edit the prop file to set visible in reflection to zero.  This mesh will have intense ambient (7?  70?)

     Make a third extrusion along the same path, but with a diameter about 2.5 times that of the neon.  This third extrusion will be the glow aura, and use the double edge blend method of texturing.

     For a photo, I'd try pipe insulation (white foam, not the black foam) with LED rope inside.

     To maintain shape, you might use coat hanger wire inside, or lay the shape out on the floor and fill the void space between LED rope and foam tubing with resin, letting that set up thoroughly before handling the outline.  Downside would be that you'd not be able to re-use the materials for another shape.

     The LED glow through the foam would be attenuated enough that you'll probably need to use a tripod and long exposure to get that neon look.

Thanks for the posts everyone, havn't been ignoring you all - detailed replies will follow in a day or so - unfortunately still clearing up after having to call out of these light making devices. The blur on the image is because it was speeding to sparky-central after a short circuit caused a water-heater timer to catch fire. Fortunately our smoke detectors are tested regularly and worked as they should do, so everyone got out quickly and safely.

Luckily apart from a few smoke marks, a trashed timer and a stink of burnt plastic, no damage. Everyones future freebies and other stuff is safe. Though consider this the next time theres an annoying smoke alarm, that timer took just a few minutes to burn out and theres enough plastic there to kill a couple of people. Kinda put all the petty poser arguments into perspective.

     Most of our "customers" here at the firehouse are taken aback by how quickly a fire progresses.  Speed is of the essence.  Thus, early warning is critical.

    Ockham made an IDL neon heart logo;  I'm working up a neon IDL MrSparky kitty...

MrSparky neon kitty.

     Kitty needs to be UV-unwrapped in order to allow for optional animated materials, so give me a little time.  :)

     Miss Nancy, I edited the emitter prop files to set visible in reflection to 0, but when I load the modified prop, it has visible in raytracing (and hence light emitter) unchecked.  Both are necessary for an object to function as an emitter.

     It appears that visible in reflection (in the text file) is just the internal name for visible in raytracing.  Thus, this trick will not hide an IDL emitter in reflections.

     If I'm wrong, somebody please give a brother a clue, here.  Otherwise, I'm back to avoiding placing an emitter in front of a reflective surface (also goes for vampyres), and hope that SM will give us a not visible in camera which actually means it.  Currently, unchecking visible in camera really means "ignored on first passage of ray, but visible on all subsequent ray passages".

     Oh, the trials and tribulations of making kitteh neon. :rolleyes:  The neon kitty logo is UV-unwrapped, pp2s stripped to remotely reference geometry, textured, and are undergoing render testing.  I'm reduced to using surplus boxes on my secondary network because the "big girls" are already tied up with an animation.

  Miss Nancy    ( ) ( posted at 6:28PM Tue, 24 June 2014  · @4159014

you desire light-emitting posersurface which, like poser directional lites, doesn't appear in reflection-only surface (zero specular)?  reflection doesn't require IDL (GIVariables), but does require raytracing, whilst light-emitter requires both.  they did fix refraction issue in SR4, but no news on any reflection fixes. 



  Miss Nancy    ( ) ( posted at 6:58PM Tue, 24 June 2014  · @4159025

or do you desire kitty tube or cardioid to emit lite and produce atmospheric fx (aura), such that said aura doesn't reflect, but tube does reflect?

seachnasaigh:
I can see from ockham's image, and remembering your previous sterling efforts on the P9 facility freebie, how that's built. Though do you think you could post some screenshots of the material settings and a test render to see the effect? For your photo, dunno if you've seen the photographic version of this or not, but in that a smiliar material and techniques to your idea are used. Called EL Wire it's thinner than LED rope, runs off a battery and the shapes are made with garden wire. I've also considered a similar idea to your resin filling, using EL with coloured sheets of A4 stationary pockets. At an expo centre (where I make the displays for their media players) their guy used LED rope lights under the display cases to light the floor, so visitors can move around safely, yet the lighting doesn't distract from the displays. It's nice stuff, much brighter than EL, but the steppers needed run at 12v so it could be tricky to power outside safely. Often during night shoots condensation or cold can be an issue, not just for the camera but the lighting kit as well. Poor battery life is a common thing. Thats where those silver survival blankets can help, keeps gear dry and warm and a few taped to cardboard can make for an massive cheapo reflector. Also handy if your're working with a live model as well :) Though as you rightly noted with whatever is used then yes a tripod and long exposure is vital. Often 30 seconds or more if you want to "walk" the light. Doesn't have to be EL or Neon either. In the 1st image below thats a kids light sabre toy, in the 2nd a USB light orb, USB battery pack and a plastic kitchen whisk where used. Like many bits all from poundland :) Talking of that shop also got another idea on the go. Just finishing off the painting, which I'll post here when done, as that would look really cool in 3d. Re your comments about the speed of fire, yea totally agree there. Especially with evacuation as plastic fumes are so deadly. Luckily we live in a great community and one of the nighbours helped us get the others out of the apartment block quickly. Fortunately this was small, contained and everyone was able to return home straight away. ___________________ ockham:

Miss Nancy:
Thanks for the tip on the script, what does it do? As for your Q about cyano-acrylate compounds not sure what you mean there. If you mean things like plastic boxes for electrical stuff I'd guess so, simply because these things are safety tested and rated. If you mean using cryanolate glues or resins for making things, then yes these are allowed. Indeed I use stuff like that all the time and it's like anything if you know what the material does, how to work with it safely etc it's fine. For example working outside, wearing googles or gloves. Also certainly agree about the fire crew, here literally in minutes and despite them being on strike. These heros have got my respect anyday, and thats real heroes, not the idiot celebs our society seems to celebrate. ____________________ nobodyinparticular:
Thanks chap and really sorry to hear about your sister. I know we where lucky here could've been a lot worse for a lot of people. Particularly the cleaning up, here fortunately here not too bad. Indeed most of it has already been done, we've got power and water again, just a little painting and some minor electrical work to do.

see above.  cage's script (in python forum) allows designation of path in poser, preview to determine interpolation method, then extrusion of circular cross-section.  should allow generation of co-axial tubes (given same path used), but haven't tried that yet.  P8 or later.

was thinking of HCl release during PVC combustion.  cyano-acrylates (used with ABS) aren't cyanogenic - I double-checked.

     Sure, I'll post screenies of the materials and test renders, plus P8 and P9+ version props, but I want to get the materials dialed in first, and each test render takes a while since they have to be final quality I'm using two lesser machines. Big girls will continue to be busy for another day and a half.

     Miss Nancy;  The prop consists of three concentric tubes, innermost is the visible neon, middle is the unseen IDL emitter, and outer is the fade-away aura.  The neon and the aura should always be visible, including in reflection.  The IDL emitter should never be seen;  only the light which it casts should be seen.

     For P8/PPro2010, I use a different emitter, which is smaller diameter tubing than the neon and thus nests hidden inside the neon.  But even when the neon has casts shadows un-ticked, it considerably attenuates the light cast by the emitter, and the smaller emitter surface area is more prone to "IDL splotchiness", and the emitter still shows if viewed through a refractive window.

...but avoid placing a mirror behind it, because MrSparky's IDL emitter shows in the mirror, as do the emitters of the wall torches.

     Materials and properties...

kitty neonneon properties.

     Neither the neon nor the aura material need to be this complex;  they could be a solid color, but I wanted to give them some variation.  Nothing more than that.

emitter MATemitter properties.

aura MATaura properties.

My render settings for the tests (yours can be quite different):

render settings

     It remains to pack the prop.  Oh, and I should save a P8/PPro2010 version as a separate prop file.  The neon tubing and the glow aura should work for P7/PoserPro back to P5, but the prop won't cast light, so delete the emitter.  You can use the gather node on the floor, walls, and ceiling, if you like.  The gather node is used on any/all materials which will be receiving light.  Or, sprinkle some strategically placed point lights if using P5-P7/PoserPro.

     Argh.  I set the clickable linked images to open in a new window, but the forum software keeps resetting them to replace the current window.

o.k., will have a go at it. reflection should be realistic, e.g. not showing full emitter, which in poser burns out to white at ambient 2 - 4, depending on colour).  there may yet be some way, if I can find photo of neon tube being reflected.  I suspect there is gonna be burnt-out centre line, due to camera response, but that it fades to colour away from centre (edge-blend).  is one example why they added tone-mapping.



  Miss Nancy    ( ) ( posted at 6:38PM Wed, 25 June 2014 · edited on 6:46PM Wed, 25 June 2014 · @4159352

have to report: can't duplicate mirror refl. issue using ock's heart prop and shaders. emitter colour don't burn out even at ambient 200, whether red (ock shader) or blue.  was surprised; expected burn-out.

ockham's free heart prop

however, not optim. in re: aura sim. will await word from them on when they enable IDL/atmo. interaction.

     My guess is that Ockham used an internal (P8 type) emitter.  Try viewing the heart obliquely through a refractive pane of glass.  What is the white band at the top of the mirror?

     Ockham, how did you do your emitter?  Nested inside the visible neon?  How did you set the pp2 properties checkboxes for the neon and for the emitter?  Or did you manage to flip some internal toggle to prevent the camera from viewing the emitter?

     By the way, the kitty neon has both an internally concealed (P8 type) emitter and an overlaid (P9+ type) emitter, so y'all can choose which to use.  I haven't gotten the thing packaged yet;  I've been fixing hardware.  In this old Dozer chassis, the processor is liquid cooled, but I fried the RAM.  So, replaced the RAM -new RAM has anodized heat spreaders- and added a rear case fan (blue) and dual fans blowing over the memory (white).  True to her name, Phoenix has arisen from her burnout.

Phoenix

PS  If you want to see detail, open the image in a new window, then look for the little magnifying glass icon down in the lower right corner and click it.  When the new view opens, click the magnifying glass icon a second time for full size.  The RAM fan set is GSkill's Turbulence II, about $15 US.

whilst I don't understand yer ref. to P8 emitter, I can say that my previous img uses red viper's e.d. warehouse.  two lite sources: fluorescent fixture in ceiling and ock's heart prop.  former is reflected in poser rounded cube, which is morphing prop secondary in importance only to amazing poser morphing bowl IMVHO.

by jove, that cooling system is impressive! in OS X we use smc fan control, such that cpu rarely exceeds 135 F.

Do you ever get those days where you start with good intentions, do a few bits then life conspires :) Been a couple of those hence the slow response, but have managed to finally finish off another real-world example of this idea, how that was made is below the other replies.

Nancy - thanks for the description of cages script. In answer to your Q's what I'm thinking is neon style lighting would be the best way as visually it looks better. But any object that could act as a light would be fine. As for your thoughts about emitter "burn out", not sure about 3D/poser, but in photographic terms theres various factors... Obviously the exposure time and aperture because it's a camera. But also things like the intensity of the object emitting light. How other lights in the scene might impact the emitting light. Type of lighting as well. Angle can sometimes also play a part as well. Take for example the "eye glass" in the image below. Thats actually a sandwich of 3 bits of coloured binder plastic along with the top of a pringles can. It's made like that because just using coloured plastic alone caused burn out, so I used the pringles top as thats semi-opaque. To further reduce the burn I also used a small door-bell light as that had a cover over some LED which gave a more wider diffuse light. Even then it took me quite a few shots to get the time V exposure balance just right. Think this one might have some light painting exposure comp on top of full manual shutter/aperture/ISO as well.

Pinky - you left the lens cap of your mind on again.

seachnasaigh - again thanks for all of this and please no rush especially given you've got machine woes. Really just a couple of quick Q's and some thoughts... When you say .."each test render takes a while"..how long would you say each one takes? In your description of how it works, would be I correct - or not :)- in saying if there was only 1 "neon" tube, that could be used to light a scene? Obviously they'd be no glow, but it would it still need a IDL emitter? Whats the difference twxit P8 and P9 emitters? In your second image with the mirror I see you - rightly - caution about placing a mirror behind it. Not sure here but I wonder if a possible the solution might be to place a flattened version of the emitter behind the IDL emitter. Kinda like how I taped black card behind the eyeglass light and the mouth to stop light from spilling out from behind the mask and mouth. Or would that cause the same effect as in real life. Noticed on the real one at times I'd get some lens flare. Yea I know cliched, but did look rather cool :) Annoyingly as my SLR has an annoying sensor dust-spot, at certain angles I was getting some odd spots so that didn't work, but could lens flares be possible in poser? BTW sorry to read you've have to rebuild part of your mega-machine. Looks like an amazingly powerful piece of kit, the cooling system alone says don't mess with me!
