GDL: Surface Orientation

Lingwisyer — Tue, 18 Jun 2019 03:59:50 GMT

Hi all,

Is there a way to rotate the surface coordinates in GDL?

I am wanting to rotate the surfaces and fills defined by the Material and Building Material commands to match the orientation of the following objects.

I think VERT / COOR may be your friend here.

Here are a couple of posts that may help.

The VERT / COOR can also be placed in a subroutine so you can GOSUB to it after any 3D element has been scripted, rather than repeating it all of the time.
You can even have different subroutines so you can align the materials vertically, horizontally, or however you want.

Ah. I had been trying those commands but had not had any success. I appears that I was missing the Base command. Should have read till the end of the chapter... Whelp...

It has been a while since I have scripted this.
But I don't think I have ever used the BASE.

I find that ...

BODY -1
PRISM (or other elements
VERT
COOR
BODY -1

.... works.

I'm not sure exactly what the BODY -1 does but it seems to start/stop (or define) the group of elements being worked on.
I might have to get the Cookbook back out and look it up - the manual doesn't really explain it.

Then the VERT/COOR must be after the element that you want to affect.
That seems a little backwards to me but it only works if it is after the element.

But maybe it is just BASE that is needed.

Without Base I was just getting the surface colour. As soon as I added it, the texture was shown. According to the manual Base resets the counter, which I am assuming are the values after VERT and such.

Thought it might be due to being in a loop, but putting it outside made it have no effect from what I have tried...
