how to use ogrexmltoflower.rb

hi!

i'm using ogre1.7+nxogre1.5.5. nxogre need some special mesh format,so i use flour. but there are some problems.

when i use flour0.32, it can convert heightfield, like *.raw to *.nxs, but can not convert *.mesh(runtime error).

so i download flour 0.4, but it no longer surpport *.mesh. and betajaen give us the ogrexmltoflower.rb, which is Ruby script to convert an Ogre Mesh XML into flower, and then convert *.flower to *.nxs.

but how can i use ogrexmltoflower.rb.

can anybody kowns that help me.

thanks!

1. Make sure you have Ruby installed (http://rubyinstaller.org/).
2. Copy your mesh.xml to the same directory as ogrexmltoflower.rb
2. Open a Command Prompt (DOS) Window, and CD to the Directory where you have ogrexmltoflower.rb in.
3. Type, and press enter.

ogrexmltoflower mymesh.mesh.xml

(Where mymesh.mesh.xml is the name of your mesh).

4. You should have a new file called "mymesh.flower" which you can then give to flower for conversion.

I you have any problems, reply back, and I'll help.

thanks very much!

i have installed the Ruby 1.9.1-p378 (RC2), and i copy the ogrexmltoflower.rb and fence4.mesh.xml to c:\ruby19,

and in dos window, i cd to the c:\ruby19, and the cmd line are like below,
c:\runy19> ogrexmltoflower fence4.mesh.xml

but the result is that,
ogrexmltoflower is not inner or outer cmd
and ofcourse there is not a new file fence4.flower or fence4.mesh.flower.

what is wrong about this?

You put ogrexmltoflower.rb and your mesh in C:/Ruby19 right?

If so; try:

ruby ogrexmltoflower.rb fence4.mesh.xml

it does not work still.

show the error,
c:\ruby19>ruby ogrexmltoflower.rb fence.mesh.xml
c:/ruby19/lib/ruby/site_ruby/1.9.1/rubygems.rb:827:in 'report_actevate_error':

Not particually helpful.

Copy and Paste the contents of the DOS window, or take a screen shot of you trying to convert the mesh file.

i have edited the last post, i don't kown how to upload a screenshort,

Okay, type in the DOS Window.

gem install hpricot

Then try it again.

thanks again and again!

but i'm so sorry, i'll type the result, it seems that hpricot failed to build.

Again, what is the error message?

below is the result,

i have checked the mkmf.log, but it's empty, nothing in it.

Try this:

gem install hpricot -v0.6

If a menu comes up choose the option that says mswin32".

error still, a little difference

Try a number of options from here:

I had no problems with installing hpricot on my computer, it is weird that you have.

thanks so much!

the ruby and the gem hpricot had installed successfully.

but there may be something wrong with your script, or just syntax is wrong, my result is like below,

c:\ruby19>ruby ogrexmltoflower.rb fence4.mesh.xml
i can only convert into convex, triangle or cloth. not a 'fence4.mesh.xml'

c:\ruby19>ruby ogrexmltoflower.rb column.mesh.xml
i can only convert into convex, triangle or cloth. not a 'column.mesh.xml'

c:\ruby19>ruby ogrexmltoflower.rb column.xml
i can only convert into convex, triangle or cloth. not a 'column.xml'


You forgot to put what it wants to be:

ruby ogrexmltoflower.rb triangle fence4.mesh.xml

ok, succeed now!

thanks betajaen for the patient guide!

any one who want to use ogrexmltoflower.rb may follow the guide below.(exactly from betajaen)

routine:
1. use ogrexmltoflower.rb to convert ogre mesh xml(*.xml) to the format flower(*.flower).
2. use flour 0.4 to convert the flower (*.flower) to nxs flies(*.nxs).

practice:
1. install Ruby and devkit (http://rubyinstaller.org/download.html)
2. install gem hpricot. Open a Command Prompt (DOS) Window, and CD to the Directory your ruby installed(like c:\ruby19).the syntax is that:

gem install hpricot v-0.8.2
any problem can see this,http://stackoverflow.com/questions/1718500/installing-hpricot-on-ruby-1-9-1-on-windows

3. Copy your mesh.xml and ogrexmltoflower.rbt o the same directory (like c:\ruby19).
4. in the last Command Prompt (DOS) Window(if you closed it, open a new and cd to the same Directory), use the syntax to convert the mesh.xml to mesh.flower. Type, and press enter.

ruby ogrexmltoflower.rb triangle mesh.xml
triangle can be conver or cloth also, mesh.xml is your choice(like column.xml). after this there will be mesh.flower in your direction.(like column.flower)
5. install flour 0.4 and follow its syntx to convert mesh.flower to mesh.nxs.(http://www.ogre3d.org/addonforums/viewtopic.php?f=6&t=11000)

Hello,

i have nearly the same problem.
If i load my program with an relativ media path like this


NxOgre::ResourceSystem::getSingleton()->openArchive("media","file:..//nxs");

i get an Debug Error:

HEAP CORRUPTION DETECTED: after Normal block.....
but i have no problems with collision. (<- i think the nxs files are ok!)

If i make the media path absolut. I have no problems and no error message.
I have tested "flour 0.3.2" and "flour 0.4".

But what can i do with the message?

Thanks for your help.

Which NxOgre are you using?

NxOgre.1.5.5.BloodyMess

OgreSDK_vc9_v1-7-0

I think there is a problem with the resource system in BM. You should upgrade to Detritus and Critter, it's far better.
