Fountain library part slow to load in AC10

[Erika Epstein]

A fountain library part by Frank Chin in 6.5 works well throught AC9.

That same library part opened in AC10 now is agonizingly slow to load and place. Why is this?
Does anyone know how to fix it?

Thanks in advance,

Erika

Hello Erika,
I downloaded your .pla file and looked at "Fountain-a".
You are right it processes quickly in AC 8.1 and AC 9
but is very slow in AC 10. I thought that maybe GS
had changed the rnd() function which is used several times in the script
but could not find any reference to a change either in the GDL manual or
in New GDL features in AC 10.
A very interesting 3D script with all that math describing a parabolic curve.
I have no idea why it is so slow in AC 10.
If anyone would know it would be Frank Beister.

I am curious about something else.
In your .pla there is another library part called "Wave"
When I tried to open it I got an error saying could not find
a macro called in the script. Do you have that macro ?
I would be very interested in what Frank Chin did in this library part.

Thank you,
Peter Devlin

Hi Peter,

Thanks for looking at the fountain object. Quite a puzzle. Let's hope Frank Beister will be able to figure it out.

Attached is Frank Chin's wave object, also freeware.
There is also a short quicktime movie that comes with it, but is too large to post.

PM if you would like me to email it to you.

Hello Erika,
Thank you for uploading the object for me.
I'm curious, where did you get these objects ?
I checked Objects on line and they are not there.
Thanks

Years ago he was actvie in archicad and on the old architalk. He posted a link to his website, now defunct. He also did a tent object.

I may be mistaken, but I think Djordje might know what he is doing/where he is these days.

Hello Erika,
Oh boy, I am just starting to figure out what Frank Chin
is doing with his wave object. I haven't looked at the script yet.
I have some guesses about what he is doing with the mesh element.
So now I have deal with this tent object
Thank you very much for the tent object.
I think I will be busy for a while.
Thanks,
Peter Devlin

That's good, as I am out of Frank Chin objects!

marin's hosting some frank chin cars on his archicad-croatia website here:

i thought he had the whole lot somewhere . . . they may be converting and posting them piece-by-piece? marin?

Interesting problem.

It seems not to be RND, RESOL or SPHERE. It seems to be PROJECT2, which slows down. Maybe because of its expansion to the third version with different display options. I have mentioned, that all evolved commands as STR (to STR{2}) and others do use the same algorithm or program code, because you can use STR{2}-flags in a STR-command.
Anyway. This problem is not solveable from outside. I will send GS a note to this, maybe they can give an answer.

But I have a solution for you Erika:

Delete the PROJECT2-command and replace it by this:

MUL2  1,b/a
w=360/nub

for i=0 to 360-w+0.001 step w
for j=1 to nuw

rot2 i+rnd(angd)-5
circle2 rnd(a/2),0,rdus
del 1

next j
next i

This gives the object a native 2D-view. The 3D-speed seems not to be the problem so it has not to be fixed.

The tentmaker object you can find also here in updated versions:

I looked for Frank Chin, when I started opengdl. It was not easy, but I do not know either, what he is doing now.

[Erika Epstein]

Frank,
WOW!

Like I understood any of that, but thanks. You are great. It works beautifully now in AC10.

Attached is the corrected object "Fountain AC10"
And thank you, Frank Chin, wherever you are...

p.s. David Nicholson-Cole always drilled into us to write the 2D script and not rely on a Project 2 statement as it is faster. But I had never seen such a blatant example of the time saved by writing this 2D script.

I am glad and grateful to Frank Beister that he was able to figure out what the upgrade in AC10 GDL meant and that he was able to communicate this problem to Graphisoft.

thanks again Frank.

Sadly, I don't.

But I do have the full set of his freeware objects, and Marin is trying to update and post them on his forum.

Yes, they are freeware ... so if the update is needed, as it is (tentmaker saved my bacon more than once!) maybe the proper place would be Frank's GDL site?

Frank? Marin?

[F_ Beister]

Hello Djordje. Selfgdl is not totally finished yet. If we will have so, I will rebuilt the openGDL site. Then we can do this more easy than in the moment. But it will take a little while. If Marin is faster, he can do. But a simple download site of zip-files should be possible anyway.

I have got an answer vom GS. The PROJECT2-command has been optimized in AC 10 and works now normally faster. Excepted, if many identical elements have to be projected. GS works on a solution. In the moment is the only way to program a 2D-script without this PROJECT2.
