Humidifier (RedSDK)
Read 2909 times
September 04, 2016, 03:25:20 PM
The attached images are in-process concept drawings of a humidifier for humidors, both done in RedSDK.  They are easily the best renders I have produced that have multiple transparent facets.

The Raytrace Fine version took about 4 minutes to render at ACIS=100.  The GI Fine version took about 1/2 an hour with ACIS set to 90 (I tried at 100, but the render started over when I simply clicked on the TurboCAD window to bring it to the front at 32 minutes when it indicated it was 60% done).

The RedSDK Luminance is Point.

Can anyone explain why the color of the battery pack changed?

The multiple transparent objects worked out really well, Jeff.

Looking good Jeff...

Not sure without looking at the materials and lighting why the colour has changed. GI renders add more light especially where raytracing cannot get in shadow areas.

I notice something we have to be careful of when using transparent materials is when they have touching faces with other objects (the orange band). It is better to either leave a slight gap or overlap objects so the black face fighting errors are avoided..

Thanks for the positive comments, guys.

Dave, the client did ask which CAD program I am using.  ;)

Nice job on the humidifier Jeff. Both versions look good.

I updated the renders.  I also figured out why one was so dark compared to the other.  Still learning RedSDK.  ;)

Thanks, Don.  I actually used the built-in Glass material and played with the lighting.

Jeff a very nice rendre job, it's a pity your not using LW as we all could learn from you.

Well done.

The customer came back and requested a new box for the controller card without the humidifier, so I produced these.

The Glass material has been modified to increase IOR for both Transmission and Reflection.  For reasons I don't understand, it gives the material a 'milky' haze that, to me, is a bit closer to the source material.

They're used to keep cigars in good condition.

In this application, the humidifier is placed inside the humidor (it's small) and water is misted on a schedule.

Nice work Jeff! Looks great!

What I would like to see for comparison? How would it look if there were all edges rounded (Especially on the Objects with glass material) ...  ;D

Thanks, Majo.

Rounding the sharp edges isn't a problem, but for some reason the rendering time for these pieces is much, much longer than for the original renders I did at the top and middle of this thread.  If you could give me a hint on how to reduce the rendering times, I'd be happy to render a new batch.

I already minimized the number of lights and was using the same materials (with fewer parallel surfaces), so I'm puzzled.

Jeff, I thought that render time will be a little problem. But ...

1. Maybe you can try a little "Chamfer Edges" instead of "Fillet Edges".
or
2. I dont know which "type" of light/luminances you are using in the scene, maybe there is some possibilities, how is move down render time. Or which are you using QR (Ray trace / Global Illumination) or ARS?

Hey Jeff.
Always nice to put our skills to work on things that will be made.
Had a thought about render time. In the originals you only had one glass plate with the cutouts, and in this version, you have two such plates.
Double the internal reflections/transmissions might be adding the time?

Hi, SG:

I thought about that, but in the exploded view of Reply #6, there are 4 parallel plates with both transmission and reflection parameters.  The battery is gone, now, but the PCB is still there, so I would think there are considerably fewer rays being reflected and refracted.

I set the Redsdk Global Illumination Fine to use the GPU and the processing time increased from 1479 to 2362 seconds.  That’s less than 25 minutes to more than 39 minutes.

Certainly not what I was expecting, based on previous experiments that Majo had posted for Pabellon Barcelona.

Any advice on what to do to cut down processing times?

Never actually tried this before, but going to Advanced and setting the Render Type to None resulted in quite fast results (18 seconds) that should be good enough.  I had to turn on Ambient lighting, but that was it.

I don't know.  I have no education on RedSDK and have been experimenting with one setting or another until something looks good.

Jeff what's the goal here, are you going to sell the concept idea, build yourself etc or is just for fun?

By the way I think you've done an awesome render job.
