aurora borealis effect
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: https://youtu.be/8NrhuBhgmjU?t=33 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
Re: aurora borealis effect
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. 2015-05-04 17:47 GMT+02:00 Will Sharkey willjshar...@gmail.com: I've been doing some research on how to achieve this effect with particles.

How do you get distance from output camera via a script
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
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.

Re: aurora borealis effect
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.

Re: How do you get distance from output camera via a script
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 Sent from my iPhone On May 4, 2015, at 1:57 PM, Greg Punchatz g...@janimation.com wrote: Hey all we are trying to figure out how to get an objects distance from the camera vis a script.
