aurora borealis effect

2015-05-04 Thread Will Sharkey
I've been doing some research on how to achieve this effect with particles.
I was thinking sheets of particles with a bunch of turbulence and other
forces:

I'm still brainstorming, Any thoughts or approaches? Would you use
particles or animated Geo and a bunch of layered animated sequences?

Thanks in advance

First idea which pops into my mind is to model geometry and having an
animated weightmap on it to use in a shader.
Somehow it looks like a mix of turbulence and gradients along of layers of
twisted / curved geometry.

I would definitely try the geometry route first. Particles will likely 
take longer to setup, provide less control, and render more slowly.


I would use geometry with animated displacement (warping), and map some 2d 
animated noise pattern textures onto them. I would use multiple copies of 
each piece of geometry with slightly different displacement to each copy in 
order to give some thickness.


Then apply glow in the post.

How do you get distance from output camera via a script

2015-05-04 Thread Greg Punchatz
Hey all we are trying to figure out how to get an objects distance from the
camera vis a script.

I am not doing the coding but I thought I could help Dave find an answer
here.He is neck deep in another script an and  he was struggling fining it
via the documentation.

I thought maybe one of you nice people might be able to point us in the
right direction.

Thanks
Greg

RE: aurora borealis effect

2015-05-04 Thread Matt Lind

Many ways to attempt this.

If you prefer working with geometry, you can create some curves and extrude 
them vertically along an axis to create a wall of sorts, then animate the 
curves wriggling as they travel across the sky.  The extruded surface can 
use a shader to control falloff.  Render the geometry as separate passes 
using constant shading for faster render times as well as full control over 
the color.  Finally, blur the passes in post before assembling.


Another route to consider is using a light, 2 bitmap textures, and a cube 
with a volume shader.  Essentially you'll shine a light onto the textures 
which act as a mask to create light rays inside the volume of the cube.  The 
rays can be rendered, colored, varied and blurred.


The cube is made large enough to fill the sky and uses a constant material 
with full transparency so the inside of the cube can be seen.  The first 
bitmap texture is a matte containing the noise pattern you want to use for 
the shape of the borealis effect.  The 2nd bitmap texture is a wash/gradient 
to drive the effect's color.  Project the textures in the XZ plane from 
underneath onto the cube.  Shine the light from underneath the cube to cast 
rays into the cube via the volume shader.  The volume shader can have most 
of it's features deactivated to speed up rendering (should render really 
fast).  All you need is the active light list, density, and colorand 
possibly raymarching step set small enough to not see aliasing.  You should 
not need shadow casting provided by the volume shader.  Shadow falloff of 
the light as well as density of the volume shader control the height of the 
borealis effect, which can also be varied by inserting a noise node into the 
rendertree, or by projecting another texture from the light or onto the side 
of the cube to act like a matte.  render the scene, then blur the results a 
bit in a compositor.  The advantage to this technique is it can be 
completely procedural, but still leave the door wide open for you to 
override that with manual control at any step of the way.

cheers. I was thinking Geo was probably the route. I actually have
something cool working with strands and a lot of turbulence. Ill share when
its actually working.

Here's the pseudo code

-Create 3 vector3 objects
-Set the first two to the global transforms of the first 2 scene objects
-Set the third vector3 to the subtraction of the first 2 vector objects
-Return the length of the third vector3 object
