How Do I Make "Gravitational" Lensing Around Shapes

Recommended Posts

I'm wanting to make a realistic invisibility cloak effect. Instead of it being a transparent silhouette, I want to make it so that there's a gravitational lensing effect that actually looks like light is being bent around an object, but I don't know how to do it around a shape other than a circle. I need to do it around a person. Will someone tell me how, show me a plugin that does, or make a plugin for it?

A realistic invisibility cloak? What do they look like? I didn't even know they're real! Do you have an example photo?

^^ what a wisenheimer I am :lol:

 

On the other hand, I've seen some artistic renderings of what an invisibility cloak might look like. For example, in those Halo games:

Is that similar to what you want to achieve?

It's possible to achieve something like the predator invisibility mode with TR's Displacement Map 3D. If the results below look acceptable to you, I can tell you how I did it if you can't figure out how to use TR's plugin (there are instructional videos throughout the plugin's thread).

The pictures that both of you showed are what I call transparent silhouettes. What I mean by "gravitational" lensing is that the light bends around it in the same fashion it does around a black hole. An example of this "realistic" cloak effect would be where a ball starts showing gravitational lensing and appears to shrink as light is bending around it.

 

Here's a picture of gravitational lensing around a black hole:

I would believe a "realistic" cloaking effect would look like it's shrinking in a distorted way with gravtiational lensing around it.

If you're talking just around circles then you can play with the Polar Inversion plugin .  It can do interesting things with spheres.

Gravitational lensing actually warps the light of stars around a black hole, unlike the picture you made.

If you read the original post, I want to do this around a different shape (the shape of a person). I am making a meme and I will show it off here when this is solved.

The closest thing I could find is SquirkleWarp, which is limited to circles, diamonds, and squares. What I want is a plugin that allows you to select any shape and make a warping effect around it and be able to set the effect radius and refraction level. I should post a plugin request. Where do I do that?

The woman in gray is showing the distortion on the right hand side of her head.

 

This effect is reasonably subtle in a static image.

Source layers look like this...

How do you make a source layer? Or can it automatically make one from a highlighted selection? Sorry, I haven't been active on using paint.net recently. If it doesn't make a source layer for ClipWarp from a selected shape, then that would be my suggestion for your plugin.

I used an outline (silhouette) of the object.  Outline the object with black then apply a couple of gray drop shadows (one external one internal). Blur the combined result before running ClipWarp.
