Blender Particle System

[coolymichael]

how do you do that?

@coolymichael

You can check out this video's comments page where I have already explained it once. If you need it more in depth you can also check out one of the tutorials I wrote about this: bit(dot)ly(slash)dnd8FS

if you still have the file you should export it in HD 1080p

I wish I still had the file! I may recreate it someday, though!

nice vid

u using the rose equation for it?

[lcc0612]

@phizikl

Hi, thanks for your comment.

This video does not use a rose equation. The particle emitter is a cube that's animated to continuously rotate and scale itself up and down - The particles being emitted from its verticies.

[phizikl]

oh ok, i thought because i found it under that keyword,

have u implemented equations like that in blender?

how easy is it to implmenet mathematical formulas ?

@phizikl

Ah, well I do actually have one or two more videos that are similar but use polar rose equations instead.

It's actually really easy. You just need to know one or two python commands.

The idea is that the emitter has a unique X and Y position - And each of these values can be mapped to a function.

If you're plotting a Cartesian graph just let X increase over time while Y will be the actual function.

A polar equation needs to be converted to cartesian first.

(cont'd)

The steps are as follows. 1. Create your emitter object 2. Open an IPO window 3. Click "LocX" 4. Press "N" on your keyboard to open the properties window 5. Click "add driver" 6. You can now use a Python expression to determine the motion by clicking the python logo Here are some functions that may be useful: b.Get("curframe") returns the current frame number m.sin( ) returns the sine of its input float ( ) makes decimals return properly That's all, I guess! xD

[phizikl]

sounds easy, but i wouuld have a hard time setting it up, im a 3dsmax user :)

if you want to set up a particle scene in blender using the rose equation i would lov to see it

if you dont have time its cool

thx for the cool videos!

[lcc0612]

OH! lol! =D

I already have videos of Blender drawing polar roses! Check out:

This one is really amazing! Do you know a good tutorial on doing such particle explosions/systems/...?

[lcc0612]

Thank you so much =)

Unfortunately I haven't been reading much tutorials with regard to particle systems because I prefer to experiment.

Good places for tutorials include BlenderNation, which has a whole collection of good stuff around the net.

Search around, there'll be nice stuff, particles are reasonably easier to understand!

[Onjas]

Thanks for the quick reply and the link. I'll check that one out.

Keep up the great work!

[lcc0612]

Cheers! Have fun with particles =)

how much bake and render time?

[lcc0612]

Bearing in mind this is a simple particle system, no baking required. Rendering every frame just takes a couple of miliseconds, even on a lousy computer (which is what I used).

[delta97baseball]

kk thnx

[Camsynth]

Is there away to make this in the game engine?

[lcc0612]

Nope, unfortunately as far as I know, there is no way to get particles into the Blender Game Engine.

There are some tutorials out there that show how to emulate a particle-like effect though.

[KasmeiPortal]

Good Job

[pendulummedia]

hey, how do you make them change colors?

[lcc0612]

All you have to do is to do the color changes using IPO. Note that the changes must be within frame 1 to 100.

What happens is, the lifetime of each particle is mapped across frames 1 to 100, so each particle will change its color across its lifetime according to what you defined between frames 1 to 100.

Thanks, great vid...(HD?)

[lcc0612]

Thanks! Well, this vid isn't in HD (I probably don't even have the project files around anymore)

But when I find the time I'd probably attempt to remake this in HD =)

Thanks again.

[TF2Chicky]

ooo... something as interesting as TF2..

[HanYou2]

looks cool. nice

[lcc0612]

Thanks!
