there is a sun demo using billboard in example StaticGeometry.pb
but this is a sun particles demo, or a giant red star, show the storms inside the sun,

the script from http://www.ogre3d.org/tikiwiki/tiki-ind ... ExampleSun
but change it a little, copy it to a file like sun.particle

Code: Select all

Nice Thing man

Sun Looks fantastic.

Thanks ApplePi.

Looks really good.

Add this at line 38:
RotateMaterial(#particle_mat,0.1,#PB_Material_Animated)

thanks DK_PETER
with the animation it looks like a solar eruption

Yeah..It's a nice effect.

Your example made me try to do a sun example myself. Mind you..I'm extremely new at this.

Here's the complete rar file:Edit [removed]

Best regards

You're right!

Hi Guys,

Please help. I've never done any 3d stuff, and this looks great.

I cannot get it working.
Exactly where do I place the sun.particle file. (Careful how you answer that, please)

Save it in your "PureBasic\Examples\3D\Data\Textures" folder as "sun.particle". And run the code in the first post.

[Edit]

As you can see here:

Code: Select all

Add3DArchive(#PB_Compiler_Home + "Examples/3D/Data/Textures", #PB_3DArchive_FileSystem)
Add3DArchive(#PB_Compiler_Home + "Examples/3D/Data/Packs/skybox.zip", #PB_3DArchive_Zip)

Engine3D will have access to Data\Textures folder and Data\Packs\skybox.zip archive. Anything else inaccessible.

DK_PETER your example are realy fantastic, i have found that there are 2 particle editors for Ogre which i have not tried yet, i hope it will enable us to experiment with particle scripts before using it in purebasic.
1- OGRE Particle Editor
http://sourceforge.net/projects/ogre/fi ... ols/1.2.0/
http://www.game-cat.com/ogre/pe/ParticleEditor_Beta.zip
http://www.game-cat.com/ogre/pe/docs/ description and tutorial
2- Ogre Particle Lab
http://www.ogre3d.org/tikiwiki/Ogre+Particle+Lab
i have downloaded it from a torrent, there was one person seeding the file
@davido: in addition to olby reply, if you add

Code: Select all

Add3DArchive(".", #PB_3DArchive_FileSystem)

then you can put the particle file in the same folder as the code file

applePi, have you found any usable Ogre Material script editors by any chance? I need something like FX Composer where changes are immediately compiled and rendered.

Posted: **Thu Aug 08, 2013 6:13 pm**

there is a material editor here: http://www.purebasic.fr/english/viewtop ... ial+editor , read the limitation there, also there are several versions go down the page
it is too slow on my slow machine, i can't even rotate the teapot by mouse easily. so i can't test, hope it will work for you it seems good utility.
i remember reading something like your quest, i remember the answer was negative, but it may be the answer was wrong.

Posted: **Thu Aug 08, 2013 6:17 pm**

That looks good enough, should give it a spin.

Posted: **Thu Aug 08, 2013 6:55 pm**

Hi Olby,

Thank you very much for taking the time to help me out.

I had put it in the directory with other .particle files.

Looks really great - Thanks applePi

Thanks for the 'thumbs up' ApplePI. I know the example is at best: mediocre.
I think it's time to dive into real 3D from now on. I'm completely bored out of my skull doing windows applications.
Appreciate the links. I've downloaded them and will try'em out for sure.

Best regards
Peter
