Yes of course!!
Thanks for your help!
I have not used the dome for some while, but I still have some scenes in my
mind for which I need the plugin. I'll let you know.

Hello:

  I love this plugin, but I am having a few problems with it.

  The meshs generated seem to be somewhat degenerate.  I tried a simple 
tetrahedron (3 sided circle with 1 parallel).  The mesh I got was:

#declare Dome2 = mesh {
triangle { <0.000000, 0.000000, 1.000000>, <0.000000, 0.000000, 
1.000000>, <-0.500000, 0.866025, -0.000000> }
triangle { <-0.500000, 0.866025, -0.000000>, <1.000000, 0.000000, 
-0.000000>, <0.000000, 0.000000, 1.000000> }
triangle { <0.000000, 0.000000, 1.000000>, <0.000000, 0.000000, 
1.000000>, <-0.500000, -0.866025, -0.000000> }
triangle { <-0.500000, -0.866025, -0.000000>, <-0.500000, 0.866025, 
-0.000000>, <0.000000, 0.000000, 1.000000> }
triangle { <0.000000, 0.000000, 1.000000>, <0.000000, 0.000000, 
1.000000>, <1.000000, 0.000000, -0.000000> }
triangle { <1.000000, 0.000000, -0.000000>, <-0.500000, -0.866025, 
-0.000000>, <0.000000, 0.000000, 1.000000> }
// Attributes returned success!

Note that several of the triangles have the same exact first and second 
coordinates (marked in bold if you are viewing HTML).

The problem I am having with this, is that I am attempting to make a 
'hollow' dome.  I was going to simply subtract one dome from another 
(CSG) but the results are weird.  If I delete the 0 width triangles, 
then it seems to work a little better, but I am left with only 3.

Is there any chance this can be fixed?

Also, as I'm trying to make a 'city dome' out of this, the parallels get 
spaced much too closly at the top of the dome.  Would there be any way 
to use the distance 'up' the parallels to space them out?

        == John ==

P.S.  I could help with the plugin if it's C++

Hello,

The problem with degenerated triangles in meshes is fixed (if you are in 
a hurry with this one I can send it to you).
Could you give more information about hollow dome (meshes are hollow) 
The other problem of evenly spaced meridians is a bit more tricky (at 
least for certain slopes), I hope I'll find some time this week to have 
a look on it.

Hi everybody,

I'm looking for beta-tester for the new domenator plugin.

I need You !

PS : Here is an exemple (a start for a new stadium ?)

Excellent!

Sure, I'll beta test.

What I am trying to do is build a 'dome city' - along the lines of a 
geodesic dome, but for (redundancy) I'm building a city with 4 'lobes'.  
 I was trying to make the glass (plastic, etc) of the dome actually have 
glass IOR, so that it looks like a series of window panes.  When I first 
starting doing this is when I noticed the bug I commented on earlier.  
What was happening is that the entire 'dome' is one big block of glass, 
rather than a hollow shell.

One idea I had, had been to take 2 domes, and CSG the inner out of the 
larger one to get a 'hollow' dome, i.e. panes of glass.  However, this 
would probably make the glass not quite all the same thickness.

You can see the weird way the buildings look in the attached screenshot, 
which gives you a rough idea of what I"m going for (most of the city 
isn't detailed properly, and a few buildings stick up too high, but you 
get the general idea).

(This is to be a dome city on Mars).

The problem with the facet/wire spacing is apparent when you ok at the 
top of the 'city' - the lines in the dome get quite closely spaced.  
Look at CityBigger-1, everything doesn't look too bad (other than the 
bad problem with the IOR, given that the whole thing is one block of 
'glass'). However, look at CityBigger-2.jpg, you can see how the lines 
at the top of the dome are looking a bit odd.

The dome settings:

 EpiCycloide, 4 sides, Parameter 1.0
 Slope: Sinus-Cosinus, twist 0.
 Window: sans.

(faces, wires, etc).  You can see a rough idea of what I'm making in the 
PNG shot of the Moray workspace, although I"ll need to make that a 
separate post.

Hello John,

I'm not quite sure to understand what you mean (English is not my mother 
language as you can read), because Domes are Hoolow, as you can see on 
the little sample below.
For the second point, I must admit that those domes are not Geodesic and 
the meridians (as on the earth) are closer to each other as you approach 
the pole.
I send you the beta version by pm (but a further enhanced version is on 
its way (features asked by other beta-tester...))

Philippe
