[Plugin] SurfaceGen (0.9.0b) — 28 April 2012
-
You are right, in that when I get v1.4 of 'recurve' I no longer get these errors with 'surfacegen'. However, I had v1.3 [with SUpv8] and there were no major changes except for making it SUpv6 friendly ?
Anyway... no more error messages... I'll try to break it

Sponge-like object:

this is great,
some odd behavior on the Mac... when run from plugins (like you should) I get this
Error; #<ArgumentError; Cannot convert argument to Sketchup;;Point3d> /Library/Application Support/Google SketchUp 8/SketchUp/Plugins/SURFACEGEN_Dir/surfacegen_tool.rb;266;in `add' /Library/Application Support/Google SketchUp 8/SketchUp/Plugins/SURFACEGEN_Dir/surfacegen_tool.rb;266;in `getExtents'if I put the surfacegen.rb into the folder do a restart and then load from Ruby Code Editor, I get this
(eval);428; warning; don't put space before argument parentheses "Run aborted (error has occurred)" (eval);428; warning; don't put space before argument parentheses (eval);10; warning; already initialized constant SURFACEGEN_DIR (eval);11; warning; already initialized constant GRAPH_SIZE (eval);12; warning; already initialized constant WINDOW_HEIGHT (eval);13; warning; already initialized constant ATTR_DICTIONARY "Run aborted (error has occurred)"but if I restart again and use as_pluginloader.rb to load it I get
/Library/Application Support/Google SketchUp 8/SketchUp/plugins/SURFACEGEN_Dir/surfacegen.rb;428; warning; don't put space before argument parenthesesit works, but has no tool button image...

That's really nice! What's the equation you used?F(x,y,z) = 2-(cos(x+(1+sqrt(5))/2*y)+cos(x-(1+sqrt(5))/2*y)+cos(y+(1+sqrt(5))/2*z)+cos(y-(1+sqrt(5))/2*z)+cos(z-(1+sqrt(5))/2*x)+cos(z+(1+sqrt(5))/2*x))*16/(x*x+y*y+z*z) [x]; -5, 5 [y]; -5, 5 [z]; -5, 5There is plenty more at the k3dsurf forum.

Perhaps you could add some more functionality; like functions min, max and abs. Also allow use of arithmetic operations and pi in axes, like -2*pi.
-
You already have 'pi' [in lowercase] as a function?

Just re-select the group with the select tool. It seems that the SelectionObserver doesn't fire when the selection is changed in code.The
SelectionObserverhas always been very buggy: http://www.thomthom.net/software/sketchup/observers/ -
Just uploaded a fairly major update to the first post!

This should fix the issues with macs. It now uses cross-platform methods to locate and load resource, and uses show_modal rather than show on macs with the WebDialog.@notareal
The axes now let you use an expression such as 2*pi@d12dozr
Helpful error message are now shown when an expression is invalid. -
Thanks
Error; #<ArgumentError; Cannot convert argument to Sketchup;;Point3d> C;/Program Files/Google/Google SketchUp 8/Plugins/SURFACEGEN_Dir/surfacegen_tool.rb;270;in `add' C;/Program Files/Google/Google SketchUp 8/Plugins/SURFACEGEN_Dir/surfacegen_tool.rb;270;in `getExtents'One minor error in
getExtentsinsurfacegen_tool.rb
Line #270result.add @p0 if @state >= 0
can raise an error so adjusting it to
return if !@p0 or @p0.class!=Geom::Point3d; result.add @p0 if @state >= 0might help - you could also add similar validity checks on the other points that are added to the extents ? -
Ah, I knew I'd forgotten something
I've updated the first post. It shouldn't show those errors anymore.
-
Cool.
The 'rand' function is also interesting...
-
Just updated again fixing a small bug with the expression parser.
Check out this graph:
Equation = min(((max(abs(y)-(2sqrt(z+4)) ,(x+0.5abs((abs(y)+4)/3.5)/(1+(((abs(y)+4)/3.5)^2-2)^2)/2 2/(1+(z-2)^2)+abs(y/1.5)^3.5/7 ) )max( max( abs(x+0.15+(y/0.7)^2)+(z-1.3)/1.4,max(z-2.3, max( abs(x+0)/2.4 -1+2abs(1.5y)+(z+0.1)/2 , -z ))) ,x-0.8+z/2)-0.1 )*(abs(x+y^2/3)-0.2+abs(abs(z+1.8)-(0.5-(y/2)^2) )^1.2 )-0.1 ),( (x+1.2+abs(y)/10)^2+(abs(y)-1.1)^2/2.5+(z-2.3)^2/1.8-0.64))
x: -3 to 1
y: -4 to 4
z: -4 to 5.4@TIG
Yes you can use any built in ruby function;)@jim
I can't make the window resizable because it is shown and hidden by resizing it to a fixed value and zero respectively, and there is no API function to get the size of the window to save it. However, you can easily change the height of the window. Open surfacegen.rb in notepad and change the line "WINDOW_HEIGHT = 320" to about "WINDOW_HEIGHT = 350". You can try different values until you get what you want. -
yes,
working on the mac...
I don't know if I downloaded before or after your latest tweak,
is there a version number somewhere on the files?another thing, is it possible to have a 'use last' settings option?
playing around with the box size on the head requires [re]inputting the data each time
cheers

If you need to use the same settings as last time just copy and paste the graph, and then change the settings you need to. All the settings are stored as attributes of the graph so will be copied with it. If you need to change the size you can use the scale tool just as easily as creating a new graph.

Also now in axes... get improvement with other functions too
-
BTW.. the varying size of content seen by jim is most likely due to your using [ font-size: 8pt; ] as although 1px=0.75pt different browsers treat pt oddly,
with safari, in SU, on my mac 8pt is reading as 8px and everything fits if a bit small.

This is very cool.
Two questions:
Is there any noise available? If not that would be a great addition.
I've tried with rand but that isn't noise.
A few links to good sites with functions and equations for surfaces would also help getting up to speed.
-
I've updated the first post with version 0.8.
@Pixero
What exactly do you mean by noise? Surely just adding (rand-0.5) will put noise on the graph? -
Thanks, Diggsey.
Just a minor annoyance. Since the dialog steals the focsus, whenever I select a Surface, my SU shortcuts don't work. For example, select the Surface to move it - press the 'm' shortcut to Move it - can't Move it because the dialog got the keypress.
