Ogre Particle Lab

Post by akem321 »

Hey,
I've been working some times on a particle editor, i've called it Ogre Particle Lab, it uses QT for the graphical user interface.
Features:

. All Ogre3D(v 1.6) default particle features availables: attributes, emitters and affectors.
. Reload resources, materials/textures and particle scripts at runtime.
. Pause/resume particles.
. Friendly camera.

EDIT>>
. Camera tab(change background color, texture or FOV).
. Light tab(usefull for shader based particle effects).
. Stereoscopic view parallel, crosseye or Anaglyph (using F1, F2, F3).
EDIT<<

Most of the time parameters are linked to 2 widgets, for example a knob(or slider) and a text input, so if the
first one is too limited in range or if the setup is not appropriate you can still enter the numeric value directly.
I tried to add tooltips almost everywhere(based on the Ogre Manual).

Here are some screens:

I've also uploaded a youtube video(in frenglish): (EDIT: old beta version)


You can download it there.

Hope you like it,
Feedback welcome.

Thanks :)
also, i wanted to mention it's better to have a screen size larger than 1024x768 otherwise you'd have to resize/move windows when starting the editor, the render window can be resized as needed so it should be ok.

Great! I tried and I love this tool.
So far I found only few things that looks a bit wrong:
- autorotate slider values are too high, it's usually rotating too fast.
- when autoratate enabled and you use left mouse button drag in scene camera jumps back. I guess you should disable left mouse button drag with autorotate enabled.
- some rotating things (for example velocity min/max) have strange limits, for example I use particles that have negative min speed. I know that I can type values manually, but that makes that rotating controller useless.

Anyway, I really like what you done, I hope you won't stop working on this great tool.

Mais oui. Je l'aime.

This is a very nice custom particle application.
Lots of useful customization features.
Lots of presets.
I like the billboard options.
Very useful randomization feature.
Installed and ran flawlessly, Win 7.
Thank you for making this available to the Ogre community.
Very nice work.

Not sure if I'll personally use this, but amazing job dude! I tested it a bit on my machine, and it's amazing! I don't think I've seen a tool quite that good before, although, I don't go looking :P

To put it simply, I was staring at it going "Ooh! Pretty colors!"

Wow this was helpful: Quatnerion and Rotation Primer

Wow, really cool. Finished and working tools for Ogre are always very appreciated, but this one looks really polished. Nice work!

Thanks! Merci! :P

@altren:

-i guess i could lower the max auto rotate speed.
-i noticed that too, yes, i will disable left mouse button.
-about the knobs and sliders values, you are totaly right about the min velocity, for some reason i didn't think about negative min velocity...this is a pretty important one, thanks.

I will check that.

some other widgets are not well calibrated, if you report them i will try to fix them.
--EDIT--
Ok, same for unit vectors, things like directions are sets from 0 to 1 instead of -1 to 1, i remember why i didn't use any negative values in first place, when synchronising widgets, i will check that too.

Sweet!

Ergonomy/layout of controllers must be pretty hard to design when there are so much options.

Thanks! hehe, i almost never speak english there, but i read/write a lot, i guess my accent must be horrible.

I had a small issue with my website but it should be ok now,
I fixed the left mouse button camera jump in auto-rotate and the rotate speed, there is also the Ogre log file activated.

@hAhni
ha, ATI is complaining about shader syntax, sorry for that, will fix it.

--EDIT--
Ok, it's fixed, should be all fine.

nice. you should marry spookyboo. or viceversa
one killer feature for me would be having the ability to slow down time
or a 'time slider' which allows me to debug the first n seconds

@ekt Thanks, very good idea, it's up.
@spookyboo Sorry i didn't check Particle Universe, i will try it, there was already a lot of features for me with the basic Ogre particles...

I didn't change anything about knobs calibration yet.

Hey,

I recalibrated all knobs and some other widgets, it is possible to set negative/positive velocity for example or
normalized vectors like direction from -1 to 1, same for colors like the colorfaders, lot of fixes,
but there is still the issue with quota...

So this is my beta-2, i think this version should be in a usable state,
but i may have missed bugs or wrongly setup this or that...
just tell me if you find big mistakes.

Thanks!

What browser/download method? Maybe you are using a download manager?
You can try to limit it to one connection, clear the cache, and not pausing the download.

Tried to edit my own particles and encountered several usability problems:
1. To load my own particles I need to copy them, edit and then copy back to see how it looks in app. There's two way to make this better: a) add resources.cfg into your application and load it, and users will be able to add their own paths. b) add "Load resources.cfg" button (I seen that in Ogre Meshy - very handy), that loads and resources.cfg from file system.
2. Camera zoom move camera by adding/subtracting some delta from distance. I have small particles (0.5 x 0.5), so I wasn't able to zoom close enough to see them well. I recommend you to multiply distance by some value (I use 1.2 usually) instead of adding/subtracting, so it will be possible to zoom in as close as user need it, and same for zoom out for very big particle systems.
3. Loading only material with "Particle/" prefix forces me to rename all materials I use and edit all particle systems with those materials. I guess you made that because you don't want to see all materials in that list, but I think it will be easier to see all instead of renaming existing materials.
4. When particle is saved you write 'CR' and then '\n', so on my system (win7) I'm getting 'CR''CR''LF' characters, i.e. two new lines instead of one. Use only std::endl or '\n' and don't add any special characters manually.
5. "Mouse released" is getting lost frequently, so if I press and start dragging scene and then it loose focus scene keep rotating on mouse move, but I already released mouse. Not a big problem, but pretty annoying.

Also, do you have any plans about making this tool open source? I think I can help you with some of this issues.

P.S. Keep up your great work.

@altren Thanks for the feedback!

1. Yes it's not very pratical ATM; i will try to add such option.
2. I'm using OgreCamera::moveRelative() for backward/forward moves;
for editing very small particles i suggest for now to approach with mousewheel, then use keyboard:
Keep CTRL(+ SHIFT for very slow moves) pressed and move with W,S,A,D keys (FPS like) to fine tunning camera view
i just tried and it was ok, i will do something like that about mousewheel moves.
3. Yes, i didn't want to see all materials in the list ...and i don't really like the combo list select btw / i will remove the filter, or an option.
4. I will fix that.
5. I have this issue too sometimes, but not frequently/not sure why...

I don't have plans to open source it, sorry:
-i have a lot of unrelated code with it.
-i have some messy code here and there.

I will try to get the editor to something functional and free for anyone who wants to use it, but that's it,
about open source i would rather join an already exisiting and larger project.
