Ogre Procedural [v0.2 officially out]

[saejox]

Great, i was planning to make an AngelScript one, since syntax is identical to c++. But this will do nicely

I have a few questions,
1. I don't like default mouse look. Can i disable it?
2. Is it possible to stop it from grabbing the mouse? [DISCL_FOREGROUND, DISCL_NONEXCLUSIVE]
3. Would you enable mWindow->setDeactivateOnFocusChange(false); ?
4. How do i create a random number ?

Thank you!

The Lua bindings are based on SWIG, which brings very little work compared to manual binding.
But SWIG doesn't have support for AngelScript...

1. I don't like default mouse look. Can i disable it?

You mean the cursor? it's not visible on my computer when the exe is launched..

2. Is it possible to stop it from grabbing the mouse? [DISCL_FOREGROUND, DISCL_NONEXCLUSIVE]

Yes, at the moment, you can still alt+tab to jump to your text editor, but no mouse grabbing at all would be better..

3. Would you enable mWindow->setDeactivateOnFocusChange(false); ?

Ok.

4. How do i create a random number ?

You can read Lua's documentation!
There's something about it here
EDIT : the standard lua libraries aren't loaded from the c++ code, I thought I read somewhere you could do it from the lua script itself, but I'm not so sure now...

I'm away from a dev computer for a few days, due to christmas stuff, but will have a look at your requests when I get back.

Thank you! No rush

I don't like default mouse look. Can i disable it?

What meant was:
It has a default fps like move mouse look. Since this is basically a mesh editor, that behavior is disrupting. A simple 'turn camera only when ALT is down' would suffice.
Thanks

@saejox : done (in the source, I haven't updated the binaries).
But there's a small bug (coming from OIS?) : if you gain focus to the main window with alt+tab, OIS considers that the left mouse button is down, until you actually click it.
If you gain focus by clicking on the window, you don't have this bug...

Thank you.
I can confirm that is a OIS bug. i have a similar program and same bug.
OIS registers mouse clicks on taskbar icon as a mouse click on application. That would be fine if it sent mouse released it but it doesn't.

• Add TextTexture class as texture modifier to draw text on texture (freetype required)
• Bugfix for a few doxygen warnings

freetype.patch

I was wondering: do you think it's too soon to ask for a dedicated sub-forum for Ogre Procedural? Everything is mixed here. Patchers could provide their patch in user-specific threads and other discussions on different topics would be more visible.
Only visibility of the forum itself would be reduced.

What do you think? Too early?

No, I agree!

Hi,
i tried to work with ogre procedural .
i downloaded it from the link in the first post
i modifate the proprieties of my project where i add the include,lib and the dll of the ogreprocedural

in my create scene i added just this line

Code: Select all

Procedural::Root::getInstance()->sceneManager = mSceneMgr;

my app do not want run , it crach

proc.jpg

if i delete it the project run without error

i use OgreSDK_vc10_v1-7-4 version

[Klaim]

It seems that your Ogre dll version isn't compatible with the last Ogre Procedural sources.
Check which version is required, then decide which to update. Sources of both projects are online for you to decide which version you want, and build it.

[johan07]

i downloaded this version "OgreProceduralSDK_vs10_v0.2.7z"
so i must download ogre1.8 ? (i use visual 2010), or if i download the version OgreProceduralSDK_vs9_v0.2.7z it work with visual 2010+ogre1.7.4

Hi,
i added the ogreprocedural to my project

in my create scene i add this line

Code: Select all

Procedural::BoxGenerator().setSizeX(2.0).realizeMesh("mymesh");

i get this error

Thanks, I'll have a look at it tomorrow

I agree, because this forum is called 'showcase', and things can get messy with several conversations interleaved.
This thread would just be for showcasing and main announcements.

I'll ask the moderators if they agree with that.

The binary SDK was compiled against Ogre 1.8.0, so you have to use the same version of Ogre to be sure to have it working (1.8.1 and 1.8.2 may be ok, I'm not sure about it)
OgreProceduralSDK_vs9_v0.2.7z is also compiled against Ogre 1.8.0 but with Visual Studio 2008.
In your case, you can either switch to Ogre 1.8.0, or compile OgreProcedural from source (it's not that hard, really instructions are here)

Another reason for compiling from source is that you'll get all the new features..

Which version do you use?
Do you use CMake in your project?
Is the version you compiled against and the one of the DLL in your execution dir of the same?

@Mikachu
Maybe you should add a small note about the required ogre version on main site (paragraph Here are the SDKs ).

hi,
i downloaded the ogre1.8 and i configurate my project to use ogreprocedural

i just added in my project "#include "Procedural.h""
i get this error

Code: Select all

C:\ogresdk\ogreproceduralsdk_vs10_v0.2\ogreproceduralsdk_vs10_v0.2\include\ogreprocedural\ProceduralUtils.h(46): error C2664: 'OutputDebugStringW' : cannot convert parameter 1 from 'const char *' to 'LPCWSTR'

EDIT
my problem is resolved , i used the seconde code in this reply .
[quote="saftschachtel"]Hi Mikachu,

congrats to the great work. I have one suggestion for your code.
In the file "ProceduralUtils.h" i replaced the code.

Code: Select all

static void log(const Ogre::String& st)
{
	Ogre::LogManager::getSingleton().logMessage("[PROCEDURAL] " + st);
	#if (PROCEDURAL_PLATFORM == PROCEDURAL_PLATFORM_WIN32)		
		OutputDebugString( (st + "\n").c_str() );
	#endif
}

Hi again ,
i fixed my first problem, i have no error no,
to use ogre procedural i just added this line in create'scene()

Code: Select all

Procedural::SphereGenerator().setRadius(10.f).setUTile(1.5f).setPosition(0,0,0).realizeMesh("mySphere");
mSceneMgr->createEntity("mySphere");

BUt i did not see the sphere , i did not see any thing !!

if i add this line in init()

Code: Select all

Procedural::Root::getInstance()->getInstance->sceneManager = mSceneMgr;

i get error that procedural::root has no membre sceneManager

I think you should first read a basic tutorial about Ogre!

(hint : you need to add your entity to a scenenode)

BUt i did not see the sphere , i did not see any thing !!

if i add this line in init()
CODE: SELECT ALL
Procedural::Root::getInstance()->getInstance->sceneManager = mSceneMgr;

i get error that procedural::root has no membre sceneManager

That's because it doesn't exist anymore (it did in the earlier versions of OgreProcedural)

[rimie2387]

yes i tried to do that before, but it does not work
i made it with wrong way
now i regled the problem

[johan07]

the ogre procedural work now with my project
i have some questions , because is ly first time to create shapes i want to know
to ceate shape like this

cone.jpg

i use Procedural::ConeGenerator() ? or is better ti use Procedural::CylinderGenerator()
and for this shape too

pelv.jpg

thanks very muxh for your idea

[Mikachu]

@johan07:
I would use Lathe (see here), it's defintely more flexible.
You can create the shape for the Lathe by using CatmullRomSpline2 (for example)

[johan07]

@Mikachu
thanks for the advice , but is tehre any code or exemple that help me to use lathe ? because i did not understand how it (lath) can help me ,why it's better to use cone shape for exemple ,
and more how i create shape for lath by using CatmullRomSpline2

[Mikachu]

@johan07:
Cone is good, it's just that it looks like a cone, which is not what your picture look like (or only as a raw approximation).
You can find sample code about lathe and CatmullRomSpline2 in Sample_Extrusion, which is included in the SDK.

[johan07]

@ Mikachu
ok i will see the sample.
EDIT
to run the sample i must create the project ? because it's not like the ogresdk sample where the sample is project

EDIT
i use cmake to generate the project
but i get this error

Code: Select all

CMake Error at CMakeLists.txt:27 (procedural_create_vcproj_userfile):
  Unknown CMake command "procedural_create_vcproj_userfile".

[johan07]

i can't generate project of the sample
any idea ?

EDIT
problem solved
