5571 Truck

Postby papacharly » Tue Oct 08, 2013 3:00 am

Hi,
here is the pretty old, but nevertheless still very amazing 5571 Truck. I built it with SR3D and rendered it with Povray.

As there are already excellent daylight renders of this model on the net (e.g. http://tubafrog.blogspot.de/search?q=5571) my idea was to create a night scenario.

Therefore I had to equip the Povray scene with around 40 additional light sources.

By the way: This digital model is far away from being perfect, as most patterned parts are missing. That means, I was not able to generate the patterned parts required.

I learned from the community that SD Pattern Creator is actually the best way for generating patterned bricks. But as far as I understood, patterned parts generated by SDPC work only with LDraw, but not with SR3D.

Might anybody give advice how to generate patterned parts for SR3D? Is this somehow possible?

Thanks and regards

Papacharly

You mean LD Pattern Creator? since LDPC creates "normal" LDraw parts and SR3D uses also LDraw parts, I don't see why they wouldn't work! SR3D shows fine a lot of patterned parts that were created with LDPC... And I agree that LDPC is the best tool for that available nowadays.

You’re right; Philo: It’s LD Pattern Creator. Sorry!

I follow your argumentation. So I already started to work through J.C.Tchang`s French manual. As my knowledge from school regarding the French language is somehow poor ( I’m German), this is definitely a challenging job. Is there really no English or German LDPC manual/tutorial available on the web? This would make life much easier for absolute pattern creator beginners like me.

I tried to translate this page into German and English, but I run out of time, so I stopped it. Feel free to send me a mail to max_martin.richter@mailbox.tu-dresden.de . So I can sent you, what I've already translated.

Hello,

now the 5571 is complete. I added all sticker parts (by mistake I named it “patterned parts” above). These sticker parts were already generated by Tchang and are available in SR3D. Great!
So there was no need to create these parts by myself. No more than a couple of days ago I realised that stickers are “alive” in SR3D respectively LDraw. But better later than never!

Adding the 4100481a sticker to 4515 was somehow tricky, as I had to avoid the LGEO 4515 part as this part is presumably not 100% identical with the LDraw definition, which results in some strange Povray renders.

I somehow managed to create my first patterned part by using LD Pattern Creator in combination with LDraw Design Pad. But as I have roughly understood the main functionality of LDPC yet, I highly appreciate your offer, Max. Thanks!

Regards
Papacharly

Awesome render. How did you add the light in the 1x1 round plate or similar? Can you post some code to add in a .pov file?

Hi Gozzi,

for the round plates 1x1 I used:

light_source {< x1, y1, z1 > color rgb <1,1,1>*intensity1 fade_distance 10 fade_power 3 }

So the lighting effect is locally limited.

For the headlight and the rear lights (at sleeper-cab top) I used a combination of a spotlight and a short range filler light:

light_source {< x2, y2, z2 > color rgb <2,2,1>*intensity2 spotlight point_at <x3, y3, z3> radius 50 tightness 10 falloff 75 }
light_source {< x2, y2, z2 > color rgb <2,2,1>*intensity3 fade_distance 10 fade_power 10 }

You easily can identify the coordinates (x,y,z) of the parts which shall be enlightened by moving the cursor (using SR3D) to this part.

Additionally I used a weak area light from above and radiosity settings:
light_source {<-1000,1000,-1000> color rgb <1,1,1> area_light <2000, 0, 0> <0, 0, 2000> 6, 6 adaptive 1 jitter circular orient }
radiosity { pretrace_start 0.08 pretrace_end 0.01 count 120 error_bound 0.25 recursion_limit 1 }

You have to play around for finding the right settings for all of the above mentioned parameters. That’s it!

Hope to see some new renders here soon ……

regards
Papacharly
