View Full Version : floating wood simulation..

05 May 2003, 10:16 AM
hi, i'm new here at this forum. hello:-)

i tried to make a floating wood simulation with the new maya5 pond feature.i've created a pond,selected the object below the water-surface,have choosed "float selcetd object" and then "create wake".. the piece of wood appears on the water-surface bumps up and down and create a wake.. but the wake penetrates the wood-object and doesn't dripping to this...

is there a way to add blobby-surface-particles (or like that) to the surface of the pond???

helloho!!! does nobody have an idea?

Hello... Let's see...

As far as I know with particles and dynamics, you shouldn't apply the effect to the geometry itself, but rather an invisible gemoetry that surrounds it.

If you are doing this to a plank, then simply create it, but also create another geometry (turned visibility to zero). Parent the plank to the invisible geometry, and apply the field to the invisible geometry. That way particles will collide with the invisible geometry and they will penetrate it, but not the plank.

Hope that helps... Good luck!!!!

sorry,i don't understand...

how does the surface interact with the particles and the

well, maybe you could create a particle emitter and emit on a grid, to have an even surface. then add this expression to the position of the PerParticle placement attribute

vector $p = particleShape1.position;

float $u = $p.x;
float $v = $p.z;
float $disp[] = `colorAtPoint -u $u -v $v oceanShader1`;
float $dummy = oceanShader1.displacement;

particleShape1.position = <<$u , $disp[0], $v>>;

it work on oceans, haven't tried it on ponds yet :)

why don't you make the wood a fluid collision object. all you need to do is select the pond , then select the wood object, and then hit the collision object shortcut in the fluids shelf

yes,maya5's Fluid can do that effects easily.

uuuhh, yes.. that's it..

i only have testet the particle> make collide that doesn't work with the fluids...

special *thx*

ahm.. where is this shortcut?

06 June 2003, 07:52 AM
you mean fluid effects> make collidge??? that doesn't work...
