3D-Extrusion Troubleshooting (SOLVED)

GnuTux · **Posted:** Thu Mar 12, 2015 3:59 pm **(#21)**

For those having problems, can you try this simple test?

1) Restart GIMP
2) Load the following .xcf

File comment: Gimp Text

gimptext.xcf [23.84 KiB]
Downloaded 106 times

3) Filters/Render/3D-Extrusion.. (using defaults.)

Should produce this..

If not, check to see if you have: script-fu-compat.init installed. It is currently required for this script.

On my system, it's located: /usr/share/gimp/2.0/scripts

That's all I got.

Wallace, yours work in my UPC. only at 270, 225, 135 extrusion direction that they don't work. You can see it in my .xcf file. Thank you so much.
I don't understand how it works at specific numbers and not at the ones said above.

GnuTux, What you say is OK in my gimp. Your text has worked OK.

Issabella · **Posted:** Thu Mar 12, 2015 4:15 pm **(#24)**

But it doesn't work at 225.

Something is different about our results. Your extrusion @ 135 is in a different direction than mine. Your extrusion direction is down and mine is down and to the left.

That is a head scratcher. :puzzled

Thank you GnuTux. I had installed the script which you said above.

I feel the same way as you Tux, It doesn't make sense.
This must be happening to other as well, but as of yet it's cause seems to be a mystery and all subsequent remedies failures.

I'm sorry this is a problem. The thing is that if it works ok in some parameters (only 3 not) it perhaps won't be very serious. I'll see this thread tomorrow as it's time to sleep for me. Good luck my friends.

Here is the code I'm using..

Code: Select all

;
; Calculate Extrusion Direction (Degrees to 2D Vector Normal)
;
   (set! hpos (round (cos (* ext-direction (/ 3.14 180)))))
   (set! vpos (round (sin (* ext-direction (/ 3.14 180)))))

;Direction
   (gimp-drawable-transform-2d-default working-layer 0 0 1 1 0 hpos vpos TRUE 0)

This has always worked for me and I wouldn't think the math to be calculated differently from PC to PC.

Thanks, Issabella. I'll post more test code later to see if we can get to the bottom of this mystery. :hoh

I even downloaded and tried Issabella's xcf file too - it worked OK for me!

Any ideas why it's not working for the other in this thread?

I have removed and reinstalled gimp2.8.10
I've re-created the 3D extrusion tut
and now everything works perfectly
possible there was something wrong with my previous gimp 2.8.10

this I quickly made to show that everything is ok
now I can experiment with the tutorial
Thanks to help find a solution
greetings gimper66

I wish I could figure out the issue that's been plaguing this tutorial and it's script usage.[/quote]

Wallace, I see that my script 3D extrusion behaves in the same way at 360º direction as 315º; and at 135 as 90. The outcomes are the same.
And it doesn't produce any extrusion at 270; 225; 180 (direction)
I can't understand how naughty is mine. :hoh

Anyway, I have two options on the right and at the bottom.

GnuTux had suggested back in post #28 that you should "check to see if you have: script-fu-compat.init installed. It is currently required for this script."

If you're using windows and you have this file, you can find it in this location: C:\Program Files\Gimp-2.8\share\gimp\2.0\scripts. Unless you've installed Gimp on a different drive other than your C Drive.
Let us know if you have this file.

Thank you Wallace. Yes, I have that file installed. I posted the capture screen in this thread. Don't worry, At least it works in three directions. There is always mysterious unsolved. hehehe.

I understand.
If you would like I could post the script-fu-compat.init file I have. So you can try it to see if it makes any difference?

Issabella · **Posted:** Sat Mar 14, 2015 11:05 am **(#37)**

OK. Thank you Wallace, I'll try it.
