Hi,

just to tell you i ve fixed the bug pointed out by ProjectIRR when rendering with ATI cards.

Yo can get the corrected version on the svn of SPARK :
https://sparkengine.svn.sourceforge.net ... arkengine/

I m now working on a particle editor, i ll let you know about the progress.

wow ...
great stuff.
respect !
thank you !

btw, how large is a 16 bit particle system at max, how big could it be if it were 32 bit ?

Juff · Post by **Juff** » Thu Nov 05, 2009 3:06 pm

Hi, thanks for your comment.

Actually the max nb of particles with 16 bit indices depends on the primitive used to draw particles :
16384 for quads (triangles)
32768 for lines
65536 for points

So it will generally be enough for most use in real time games.

The 32 bit indices system can hold far enough particles... well let s say a lot more than any system can render in real time (more than 1 billion quads)

stunning particle system, unfortunatly broken with irrlicht 1.5,1.5.1 and 1.6

I hope I am doing something wrong as I want to include this in my project to make it much more pretty

;0)

** updated
now I am confused, have also compiled with irrlicht 1.3,1.4 similar errors
hmmmmm what version of irrlicht.dll is included with SVN????

Juff · Post by **Juff** » Fri Nov 06, 2009 5:22 pm

Hi,

The Irrlicht version used is the latest (1.6)

I guess you have a problem with your includes.
The include path of Irrlicht in your IDE must be the 1.6 one.
All the errors you have mean Irrlicht has not been correctly included (as all the missing symbols you got are normally defined in Irrlicht)

btw dont hesitate to ask your questions directly on the forum of spark. As everybody directly ask questions on the spark topics on different forums, the spark forum is not very lively. Moreover it will centralize the information.

Great job, the particle system looks awesome. I particularly like where you write "spark" at the end of the video and it expands and disappears. All in all, great work!

**EDIT** Also wanted to suggest adding a screen shot to the screen shot of the month competition, I personally really like the first screen shot. I suppose you do not get the full effect until you see it in motion though, perhaps the video of the month contest thread?

Keep up the good work.

Thanks

Unfortunately this demo is not rendered using Irrlicht but using the native OpenGL renderers, so it wont have its place in the screenshot of the month. But I hope someday there will be a screenshot of the month with some particle systems from spark in it.

Mmm looks very nice! Will certainly give it a download and see if I can make use of it!

Juff · Post by **Juff** » Tue Nov 24, 2009 6:20 pm

Hi,

just to tell you i have fixed a couple of bugs in the Irrlicht module :

There was an array index out of bounds break in DEBUG mode in the IRRQuadRenderer which is now fixed (the data accessed was valid but the current size of the array was not that is why it was working correctly in release).
There was a conflict with deletion between the SPKFactory (which is responsible to delete registered systems in SPARK) and the scene manager of Irrlicht, it is now fixed.

You can get the latest version of SPARK from the repository. In addition to those bug fixes, there s a lot of new features as well.

Here is a new demo showing a more complex system with SPARK : an explosion. The rendering in the demo is performed with native OpenGL but can easily be done with Irrlicht by changing the renderers.
You can get it from here or from the SVN repository.

Just a small piece of news : after having developped the IrrRenderer with Juff, I'm now creating a particle system editor. More information to follow as the dev go.

PS: and sorry for my bad english

anoki · Post by **anoki** » Mon Dec 07, 2009 8:32 am

This looks really great ! I tried all demos with my NVidia 7300
with XP and runs fantastic.

When do release the next versions ?

cool. looking forward to this. I may use SPARK in my project, would be good to have an editor.
