Hello there, I'd like to create an air-crafts explosion in the air.
So, I would appreciate if anyone could give me any ideas on:
Dynamics for collision of 2 air-planes when they hit each - other.
Explosion (fire ) effects to make it look real.
I am new to Houdini (6 months), so at the moment I am trying to make what I've mentioned by RBD Houdini, and investigating the Sprites in Houdini for fire.
Perhaps, you have better idea or tutotial or an example, or even the link to those topics.
Best regards,
Jamolhon
if you can, please write me on: ahmedov_j_u@mail.ru

Modell the plane in SOP and the use the Cookie SOP to split up your airplane in the pieces that will go into DOP and be the actually chunks that are ripped apart when the airplanes collide.
Look for help in houdini help and search for
Cookie Sop
Glued RBD object
Collision Data ( for particles to be generated from the chunks that rips apart)
A good tip is to buy the Rigid Body Dynamics DVD from Gnomon.
It's great.
Have a nice help surfing in Houdini
Good Luck

Hi Jens Martensson,
thank you for your help.
Have a looka at test animatics, that will give you better visual understanding of the project:

and test DOPs test that I've got at the moment:

However, I am looking for how to creare the explosion itself. Now I am testing the sprites, but I am sure should be more other ways.
Do you know any particular tutorials about explosions. Video or paper or ….
Thanks.

You might try
http://www.miguelperezsenent.com/ [miguelperezsenent.com]
and check out the Meteor tutorial
he is using deep shadows and sprites and it
gets a very volumetric look.
This might be a good direction for you to try.

Hello Lyn,
Miguels meteor example working fine and look OK.
But, I have noticed the sprites are very censitive to the lights, so as soon as I move them the effect of fire is gone.
Can you tell me what is the solution as to fix the lights to the camera? or the lights should be directed / looking at sprites at certain angle?
Thank you for your help,

As sprite are “camera based” (always facing the camera) you have to make some consolations as to how far one direction or the other you move your lights. This is just a function of sprites.
You just have to be creative as to how you use them.
One thing I do sometimes is to create a seperate set of light just for the sprites, always with an eye towards the compositing stage.
You can also do things like copy spheres to your particles and shade them to use as shading control in your comp.
Normal maps might also be a good option.
additionally you can setup your lighting in an RGB fasion
for example ( green = key light, red = fill light blue = rim light)
so that you can color correct and control the light in comp.
