Just beautiful!

I don't know how I missed this one, well been kinda busy and one of the compters on the lan has become infeted with a wretched virus, anyhow, this is an amazing model, it looks so real, and the detail - I am surprised it rendered up so quickly, as you may know my record render took about three weeks (500hrs) and broke before it was done "splash". I will point out though, before anyone else does, that 4000x3000 is only the limit for rendering "on screen" so to speak, if you render to disc (file menu) then you can go to ridiculous resolutions, set up all the dpi and so forth, only thing is you can't stop it and resume you have to let it do it's thing - on the plus side I think you will find it is slightly faster. Big renders I usually do at 7200x5400 that will give adequate dpi to print out at 24"x18"... that's 300dpi. BTW I have never heard of the modeling software you are using - but that's not surprising - I'm playing with wings3d at the mo, doubt I'll be producing anything like as complex as this baby. Phew, good work. How about a GB500 cafe racer, that's my bike? :0)

Ah

Well you see i drew that in 4 weeks at about 4-5hours a day and all weekends, with a laptop up by the bike itself so its the most accurate model ive ever done we are talking everything is there stripped down the bike and drew every part individually, www.ptc.com make pro/desktop i also have started to use solidworks2004 which is simmilar but does stress analysis and other funky stuff! I'm currently constructing my 9ghz rendering rig comprising of 5x 1.8ghz durons stacked up, have drawn 3D designs and am waiting for the pannel work to be lazer cut. will be running the system on bryce lighting and a stripped down version of windows, its gonna be the muts nuts!

Sounds expensive!

So once you've got all this processing power how about rendering the modle of the bike with more interesting materials, maybe something semi-transparent and colour coded so we can see all the nuts and bolts inside? I'm fidding around with plastic and metals at the moment, either trying to get them less than perfect or introducing more frosted reflection to give a better abmient light feel to things and avoid the multiple fanning shadows you get with multiple light sources. Not for any special reason you understand, I just like to try things out.

Yea i see what you mean

It just takes ages on my current rig to render "true ambience etc" (3ghz P4@3.2 2gb Pc3200 DDR ram dual channel) and also i have to keep turning off hyper-threading as bryce doesnt support it, you on msn messenger seing as descussing through here is annoying/slow. With regards to the cos the components have cost me 400quid so far and i am scrounging for PSUs etc so hopefully cost finnaly about 500quid! I have a huge collection of metals at the moment that i have collected of the net so if you need some i have some availible.

Hyperthreading

I've contemplated the hyperthreading issue, but I don't turn it off, I just run two renders side by side - and if your really crafty you can do the same render, one top down and one from the bottom up but you really have to put some care into camera angles and sun position (it all becomes a lot simpler if you don't have your sun linked to your views - then you can just flip the camera in the z plane). Just a thought. I don't know what effect turning the hyperthreading off has, I've never done that, does it help in any way? I've benchmarked some upgrades on mine and I can say that memory makes a significance difference and faster hard drive access time also improves render speed over the long run - maybe because I tend to favor rendering to disc?

Sounds Fruity

well turning it off isnt exactly difficult and seing as bryce can only use up to 50% of your cpu with it on turning HT off i usualy get a steady 98-99%usage so thats pretty much halfing the time taken to render, stands to sence really but i havent tested it yet. Waiting for the quote to come back on the Laserwork for my custom case :s. Surely its much easier to switch HT off than risk camera alignment?! and also wondering on my upcoming render machine whether 128gb DDR kingston Ram would be sufficient for them?

128gb!

Wow! Now that's a lot of ram. I just upgraded from 512mb to the full 1gb and I reckon that gave me as much as 30% reduction in render time. Now as I understand it the hyperthreading works by sharing the processor out by two identical subsystems built into the processor, the idea being that the kernal is left idle a lot of the time while comunication carries on in supporting systems therefore by using two support systems it can make your single chip look like duel processor to the right motherboard. Therefor you have to ask, a) with rendering being so numbercurnchingly intensive are you going to feel the benefit from HT technology or b) if turning it off is only going to result in halving the effective speed of your machine even though the task manager may report 100% use that's only 100% of half your machine, effectively 50% in other words. Now I don't know the answer to that, but I'd feel inclined to run some benchmarks with renders to find out because it could add up to a lot of lost time in the future if you don't get it just right. My money is on halfing the speed of the machine if you turn off HT - hence I run mutiple renders - which XP seems to cope with very nicely I have to say. Anyway, do let us know if you find out the answer.

I wish

I suppose thats thets the benifit of proof reading, anywho did a few render experiments to sort out the HT mess.

1st Render:

Second Render:

So it seems you were right that it make nowt difference in fact disabling it make things worse!

Never the less with the render sever im using Durons so HT isnt an issue, Will add more RAM when i have the case as 5 sticks of 128MB cost 80quid or so, you can see why i only bought 128MB!!

Funnily enough...

I spent the money I could have used to put my bike on the road on upgrading my computer. I'd say that 128mb was pushing it a bit for windows XP and I'd also say that anything other than XP was a waste of time. But speaking as someone who mends washingmachines and vacuum cleaners, tiles bathrooms, fits kitchens and rewires houses for a living - I'm probably not the person you should be taking advice from with respect to your computer. :0)

Anyway

What sugestions do you have on the soft lighting/shadows and whats this beanzvision HGL system all about? Had a bit of down-time recently internet was cut off and i had to remove the water cooling from my Rig as it just wasnt working right oh well! Any suggestions/lighting tips?

HGL system

It's a dome made up of very soft single point lights, lots and lots of them, thereby filling in the shadow regions with diffuse ambient light - as you have probably observered standard ambient light does on interact well with bump or modelling, so if you replace that with diffuse light you get better 3d effect - I think it's called radiosity, but don't quote me on that because I've only just got interested in it. Anyhow, I believe you can download the HGL system through a link on his GLS lighting tut pic - or visit his website bryce5.net and either look in the free goodies or put out some feelers on the forum. And/or look at my spikey torus knot pic and contemplate a few experiments. Bsolutions is an excellent site for non-documented functions in bryce, you'll find a fake radiosity effect explained there - the one I used on the harvester pic - that's a processor melter too. If you look on the forum associated with this site you'll find a thread reguarding useful links. You could also visit my own site and take a look at the free resources - I'll post when it gets updated, but there might be some useful skies there to start you off on a lighting mission. One final word - soft shadows - if you want them then you have to build them into your sky from the start, some weird bug this, anyhow, my advice is go from default sky > sky lab > bottom of sun and moon tab there is a radio button set that and save this sky - then fiddle around modding this sky to suit but... be aware, the soft shadow option is not for the faint hearted - used in conjunction with the HGL system it will put the brakes on your renders. Never fancied water cooling - water + electronics = :o( I've settled for a big noisy fan that runs at about nearly 4000rpm - that just does it. But only just!

Just a quick question...

I was showing this pic to my friend and we happened to observe that the chain seems to have gone astray - where did it go?

Good point

it took me 4 weeks to draw but then when i thought i had finished i realised i hadnt drawn a chain! needless to say i was not best pleased and to be truthfull couldnot be bothered to draw howevermany links of chain there are, as im about to set up a big render i might sort out the chain tonight, thanks for the reminder!

An instructive tale...

My friend stripped his bike down to nuts and bolts, cleaned each component loveingly and rebuit his dream machine from the gound upwards. Once he was done, he proudly dispayed the fruit of his labours to his girlfriend, thinking she would be impressed... "Is this part of it?" she asked, holding up the piston! Oh dear... Well, at least the chain will be modular I suppose. And I do hope we get to see this big render! :0)

Classic

Yep just doing a trial one now have modeled the chain looks great with all its pins etc! Also re-worked the fueltank as it was a bit square if you noticed above! at the time it was giving me grief so i hashed it a little but now its all sweet and curvy just like the real deal! I have a picture of the real bike here next job before large render is to sort out decals which im not too sure on and more importantly to get the render sever up and running give it a month or so!

YOU TWO ARE NUTS!!!

Max3d,davidbrinnen...I can't believe the values I'm reading(300 components,7200x5400,etc.). Why you two need to render your images in such high resolution?You are going to make posters,or what?By the way, ahve you heared of ICQ?
Anyway, a great model. Infact, that's the most realistic object I've ever seen(compared with the picture of the real thing)! You should know(you probably do) that some people sell their models, and that one is definitely worth it. I can't believe you made the model in bryce5...it looks like only the materials and the background are made with bryce. Just BEAUTIFUL!!!

Thanks

boen_robot, i didnt model the bike in pro/desktop, bryce isnt too hot for that! The room as you pointed out is bryce! Just waiting for PC parts as its running in safe mode at the moment! Cheers for the comments, im thinking of selling it on 3d02.com as they said the images were of the standard they wanted. So thats the badness. Also i rendered it so large as i printed it off A0 on the plotter in the house, very nice output.
