wow Whaat, how long it took to write 62954821 lines of code ?

you should add some error checking when you getElementById, maybe the DOM didnt finished rendering the HTML code when you are running the JS code. best way is to have a function that does getElementById and error check and then returns the object back if it is valid.

also ask the user to open the HTML in IE and see if it gives the same error (maybe a better line address as it is not in the shell anymore)

1) Does the MAC version of SU also use the Internet Explorer Shell?

as Gaieus said on Mac there is Safari shell

2) What if you don't have Internet Explorer installed on your machine?

a form of IE is inside every Windows, mshtml.dll, that is used by other components and IE as well.

3) Is it possible that the javascript inside a Web Dialog can be blocked by a security feature of Windows Vista or Internet Explorer?

usually the javascript is allowed on files on the computer but can be disabled via registry

also check for antivirus/firewalls that can disable/change scripting

because WebDialogs are not using the default browser installed on the user machine, but instead a Internet Explorer shell (the same that you see when viewing .chm files for example) on Windows version.

there is no option to use other browser engine for displaying WebDialogs.

btw, why do you need another one ?

sometimes (have a Powerbook G4), but this is what I used in my TimeTrack plugin and it worked for Mac users.

how about using Sketchup.find_support_file "Plugins" and then File.join(Plugins_dir, filename) ?

great work Whaat !

also check with entity.valid? before doing stuff on an entity like this:

all_ent = []
Sketchup.active_model.entities.each do |ent|
  all_ent.push ent
end
all_ent.each {|ent| x.erase! if ent.valid?}

because the internal function length is done in C world and those 3 scalar multiplies in Ruby world (which of course is slower)

why this testcase doesnt work ? I am missing something ?

later edit: duh, vtmp = v.clone otherwise it will change the original vector
from my tests scale2 is like 26-30% speed increase

def scale(v,s)
  Geom;;Vector3d.new(v.x * s,v.y * s, v.z * s)
end

def scale2(v,s)  
  vtmp = v; 
  vtmp.length = vtmp.length * s
  vtmp
end

v1 = Geom;;Vector3d.new(5,1,5)
n1 = 10

t1 = Time.now
begin
  50000.times do |x|
    scale2(v1,n1)   
  end
rescue => err
 p err
end
p Time.now - t1

Adam: bsp importer is done in Ruby ?

nice work a4chitect

Viktor: I proposed to Adam a collaboration but it seems it doesn't fit the roadmap

Biebel: Q1, Q3 - yes. regarding Q2, I dont know as I didnt saw any textures in the videos, only color. doing multitexturing (texture + lightmap) only in ruby will be slower

unfortunately it will not be free (unless someone will sponsor the development)
also it is Windows only due the tricks involved.

it is a plugin and can be activated/deactivated (even if the impact on frame per rate is minimal)

it needs some finetuning, but this all depends on the user feedback - higher feedback, higher priority

... and it is not SketchUp 7

I used 2 .avi files - they can be rotated, scaled as normal textures on a face.

enjoy

thanks guys !
and here is my present for you

how about loading a complex model (with textures, transparent materials, sun activated, ...) and typing in Ruby Console Test.time_display

but if you flip red and rotate blue 180 it is not the same as doing a flip on green ?

t = transformation.to_a
p t[0] < 0 # flipped on red?
p t[5] < 0 # flipped on green?
p t[9] < 0 # flipped on blue?

unfortunately I dont have time right now to implement it, but you are free to add it. hope that you will share the modifications so I can add it to drop.rb.

thanks for the suggestion
