  Help a noob start designing elements
Posted by: Giorgos Solomonidis - 2016-12-06, 19:10 - Forum: Help Wanted - Replies (1)

As title says guys, I use mlcad το create my digital models, and povray to render them, and from time to time I ask your help to design a new element thats not in the database yet (and you helped me everytime I asked)

Thing is I want to start designing .dat files for my own custom elements.

Can you point me where/what to read? and a basic workflow? which programs I should use in order to achieve this?

Thanks a lot

  TEXMAP searchorder
Posted by: Roland Melkert - 2016-12-04, 20:59 - Forum: Official File Specifications/Standards - Replies (3)

I'm a bit unclear on the texmap search order, working with the 10054p01 helmet Philo made a long time ago I noticed it failed loading as it couldn't find the png's.

I fixed the issue by coping the png's and adding it to LDCad's buglist.

I'm now addressing the bug, but I'm wondering if it's a bug at all, it concerns this file structure:

Code:
Helmet\10054p01m.dat
Helmet\s\10054s05m.dat
Helmet\textures\10054s05a.png

10054p01m.dat references "s\10054s05m.dat" which references "10054s05a.png"

LDCad currently looks for the png in these places
Code:
Helmet\s\textures\10054s05a.png
Helmet\s\10054s05a.png
<ldraw>\parts\textures\10054s05a.png
<ldraw>\parts\10054s05a.png
<ldraw>\p\textures\10054s05a.png
<ldraw>\p\10054s05a.png

The spec doesn't mention it should also look in the parent's textures folder, LDView seems to do so though.

I think the png's, in this case, should be located in "Helmet\s\textures\" instead of "Helmet\textures\"

  Wondering about FOV
Posted by: Roland Melkert - 2016-12-02, 19:56 - Forum: LDraw Editors and Viewers - Replies (3)

Width all the POV-Ray exports I'm doing lately I'm wondering about the field of view angle.

Mainly because I changed it to 45 degrees sometime ago and forgot all about it, so when using a clean setup I noticed something weird about the renderings in LDCad, this of-course is the default 75 degree FOV it uses out of the box Smile

So now I'm wondering to change that default to 45 or not.

I also experimented with a simple macro script to help calculate a realistic FOV angle.

Code:
function runFOVCalc()

 local w=tonumber(ldc.dialog.runInput('Width (e.g. in centimeters) of the editing area.'))
 local d=tonumber(ldc.dialog.runInput('Distance (using the same unit as width) between your screen and eyes.'))
 
 local angle=math.ceil(2*math.deg(math.atan(0.5*w/d)))  
 ldc.dialog.runMessage('The optimal FOV angle is about: '..angle)
end


This gives 38 degrees for my setup (36 cm editing area width excluding the bins and source windows left/right from it, at a distance of 53 cm)  which seems low.

I'm I missing something here?


Anyone has some more insights on this

  POV-Ray: Transparency using fade_color
Posted by: Niklas Buchmann - 2016-12-02, 15:15 - Forum: Rendering Techniques - Replies (6)

Hi everyone!

In Roland's thread POV-Ray export questions, Christoph Lipka suggested using the fade_color mechanism to render transparent objects instead of filter/transmit.

I've been playing around with the settings for a while now and while the results look promising, they are not quite where I would like them to be:
   

What I think is missing is some 'milkyness' in the transparent parts, some scattering of light inside them to make them glow. This is especially apparent for transparent parts in front of a dark background. Using a scattering media might be a solution, but that only works on hollow objects.

Has anyone else used fade_color before and can give some advice?

  LDraw OMR side
Posted by: Michael Heidemann - 2016-11-28, 16:15 - Forum: Website Suggestions/Requests/Discussion - No Replies

There is a link error just on the front page: http://omr.ldraw.org/

How can I submit my files?

If you have LDraw files of official LEGO sets and you've made them OMR compliant, you can submit them here at the LDraw forum. At the moment we don't have an onsite submit form.


The link to the forum is wrong.

  Flat Posting Style
Posted by: Orion Pobursky - 2016-11-22, 21:05 - Forum: Website Suggestions/Requests/Discussion - Replies (10)

Flat posting style seem to be the predominate forum style this days. While I prefer threaded view it is rapidly falling out of favor with new users. Being very aware of trying not to impose my biases on the newer crown I'd like to ask the user if we should do away with hybrid m-threaded view and go flat posting only.

Note: The threaded view option won't go away but it is slated to be removed with the new version of MyBB (whenever that happens).

Hybrid Threading (current default, replaces flat):
   

Threaded (user selectable, not default)
   

Flat (no indent like hybrid, new posts always at the end, paginated)
