LCD screen

[Matt_ID]

Hi guys,

I'm an industrial designer and there are many cases where I have some type of LCD screen on my products. Up to this point, I have been rendering products in one way, and I was just wondering how others may approach the situation with Vray.

Typically, I have actual thickness to the lens, (be it 0.2mm), apply a clear material to it, and I apply an image as a map for Emissive color on a surface that is 0.1mm below the lens. The below image is done with this method, and the intensity of the Emissive color is set to 5 in this case.





Having actual thickness to the lens adds a little more realism with the light hits the edge. (Please ignore the low rez reflection map).

This is a quick sample with simple geometry, but transparent materials always slow the rendering process down.

Is there a way to cut down on time? Any tricks you guys would like to share? I'd like to know how to and what to model, what we can get away with render/material settings.

Thanks,

Matt

PS. The UI design is something I grabbed online and slapped onto a sample here.

Re: LCD screen

I think it is pretty good workflow and the render time for that test is good as well. You can use the emissive material alone without the glass geometry, but you have to add one reflective layer to the emissive material and add some transparency to the emisive layer. For close up, I think that your workflow is good.

Re: LCD screen

While we are on the subject of translucent materials,

What is the most "translucent material" friendly visopt? I'd definitely want to keep refraction on, but as far as tweaking visopt, I don't know what settings can speed up the process without losing quality.

Re: LCD screen

The Max Depth on the Global Switches allow you to controls the reflection/refraction depth. The default value is 5, if you decrease this option to 2 or 3 you will save some time on reflective and refractive materials.
