View Full Version : How to create a block hole / event horizon

Hi Anyone go any suggestions or tutorials they could point me at that will help me create a convincing black hole?

Thanks for any suggestions

take a preset for a volume light from http://presetcentral.com/

Do you have something in mind in terms of final look? Since nobody has seen a black hole its anyones guess what they might look at the event horizon :)

Can you be more specific, i don't think anyone has ever seen a black hole, besides the obvious refractions/distortions that happen at the edges because the gravity bend the light traveling past it.

Are we talking a Deepspace nine wormhole type thing? or a black hole as seen on the movie Sphere (the Unknown event log)?

I'm doing it to help a student with a film/educational video project for kids - he has a things in mind including a gravity well typically shown using a flat plane with a grid being pulled down a tube but also wanted to show someone being stretched along the curve of the light beams that are being sucked in - not sure how accurate this is scientifically -

May be using refraction sphere will give something that looks close. I suppose in real world there are defflections of light extremely raising towards event horizon. Personally i'm more interested in how to create realistic animated accretion disc.

As far as the stretching goes, in case you hadn't figured on a solution to that, it may be that a lightwave tut on morphing an object based on distance is right up that alley - on the "24 hours of Video Training" link, there are a couple of tuts. I like the one using the Node Editor - very nice. Search for "
Localized morphing of an object based on the distance of another object:" - should lead you right to it, if it is of interest to you.

for something really convincing you need an even bigger large haldron colider! :) hehe..

Apparently we just need to give our current one some time, and we'll have our very own black hole! Although rather small in size, and provided it doesn't vanish in a puff of probability, I imagine it would be no less disastrous over time. (Hyperion, anyone?)

I found this on wikipedia, maby this will help You to come with some idea to visualise an event horizon - it's a "simulation of Gravitational lensing by a black hole which distorts a galaxy in the background." this what You see is an event horizon, couse as Hawking discovered, You can't see the black hole - the naked singularity itself, need to be covered by an event horizon

Does this have to be done in LW?

If ever an effect was screaming to be done in comp....this is it :)

Refraction, may be controlled with gradient using Fresnel node as input... In addition some node things to fake background light amplification and spectrum shifting.

actually, this might be a valid use for lw's lens cap plugin....
