Under the Refraction section of your glass material, change Affect Channels: Color Only to Color + Alpha Which leads us to: it actually is not the background you see there, it's the illumination that your background gives to your refractive object to calculate its refraction, even if you try to mask it with alpha channels, and / or render elements, it will be visible so what you are getting is perfectly normal. I know what you're thinking.As a rule of refraction in 3D world, your object which has refractive material (your glass here, in this case) is processing refraction with the illumination of your native background when you hit your render button.

If you want to build a business off of this code you should probably hire someone who knows how to program professionally in Julia. In short: To me this code is a fun side project. The original paper suggests a better way of calculating loss but I didn't implement it because the naive way was easier, yet I rolled my own mesh utilities and Poisson solver because I enjoyed the challenge. My units and notation are inconsistent throughout. I have extra negative signs that I inserted that make the code work but I don't know why. I am a novice at programming in Julia so if you have suggestions for how to improve this code, please reach out or make a pull request!Ĭaveats: There are a lot of issues with my code. If you continue this work in some way, please cite them. But the slope of the glass, \frac whose divergence equals the loss:Īll of the math for this post came from Poisson-Based Continuous Surface Generation for Goal-Based Caustics, a phenomenal 2014 paper by Yue et al. In other words, the height of the glass h(x) is not on its own important.

Whether two rays converge or diverge is controlled by how curved the lens is where the glass meets the air.

The angle between the incoming light rays and the glass-air boundary has a strong effect on the refracted ray angle.

The first transition, from air to glass, can be entirely ignored. We could add material to the left side of this lens and nothing would change. This style works best with one or more transparent layers on a bright, colourful background. Multi-layered approach With objects floating in space, the layered interface maintains a clean look that’s easy on the eyes.

The overall thickness of the lens does not have a direct impact on the outgoing ray angle. The blurring of objects gives the layout a sense of perspective, almost as if they were floating in 3D space.

Zooming in on one small section of the lens we notice a few properties: The caustic image from this lens is dark everywhere with one very bright spot in the center. If all the incoming light is from a single, very distant light source like the Sun, this lens focuses all of its incoming light into a single point. This lens forms the simplest possible caustic.
