First prototype of visualizing rays. Fairly simple implementaton: store rays in UAV, then do ray-cylinder intersections in a CS. First bounce is green, second yellow, red for the rest. Shows how dumb my tracer is with very little importance sampling, but it's fun to watch!

Always dreamt about such feature but were too lazy to implement. Havent understood ray-cylinder part, during visualization stage?

I used a ray-cylinder intersection from Basically I save off all the rays into an array, and then trace against them in a for-loop treating the rays as cylinders with a fixed radius size. It's brute force but good enough for a prototype

Why ray-cylinder?

Lets me easily specify the thickness of the ray visualization

Good afternoon, Rays Twitter. Here is what SportsCenter looked like from May 9, 2008, with Robert Flores on the call. • Rays reach three games over .500 this late in a season for the first time ever (!!!) • The lore of Complete Game James begins • Longo’s first walk-off HR

I asked the question to the referee : “is there only enough room on the back of the card for my name today?” In a joking manner and he replies “no just your name” and shows me a second yellow. Yes frustration then got the better of me but for throwing the arm band a second red?🤡

“i think a couple of cars went just straight in turn 2 and 3 and then they rejoined like 3 or 4 cars in front of me. so a little bit unfair i would say but it's the second time in a row that the first lap first corner the fia is looking to the other side.” my fav fia hater😍

BARTIROMO: How much time is it gonna take? LUTNICK: We own the economy in the fourth quarter. First and second quarter are sort of a little bit our optimism ... but it is the mess that we were left with, but it's not that bad

$The most historic experiment we had on board was a tech demonstration: The first ever X-Ray taken in space. Project: X-Ray ⚡ Question: Can we take good quality X-Rays in space? Fun facts: - Due to bone loss in microgravity, fractures can become more likely on long duration missions - so we need a way to diagnose these. - X-rays can also be used to have a look at faulty electronics! The most fun picture we have is one where we captured our chest plus a wearable sensor, so we got both objectives hit in one go. - The first X-ray in history was taken in 1895 of Wilhelm Röntgen's wife - here next to our recreation in space. Find the full list of research projects here:$

I'm so excited to reveal not one but two covers today! The first is the movie tie-in edition of How To Train Your Dragon, coming in June, and the second is the gorgeous new edition of How To Be A Viking, first published way back in 1999! It's going to be a Dragon-tastic summer🐉

Medusa's introduction. This to me is the greatest scene in Ray Harryhausen's career. Pure horror. For best results it's best to watch it as a kid for the first time. Clash of the Titans influenced how Medusa would be portrayed in future media.

Been waiting for this moment. There is a lot in my head that I must process and very little has to do with leaving the planet. Today is my first step. I have never in my life felt peace like this.

🚨 WOW! Vice President JD Vance reveals he initially was not a Christian, but then started to realize — "If the Christians are right about the importance of virtue, and they're right about the importance of being a good father as opposed to how much money you make, and they're right about the importance of being a good husband as opposed to how prestigious your job is, then maybe they're right about these more fundamental questions!" "I start asking, how do I be a good husband? How do I be a good provider? How do I be good at the things that actually matter? And the more that I asked those questions, the more that I felt like Christianity had the best answers. And it's interesting that that really is how it started for me." "I didn't have a conversion on the road to Damascus. But I started to see these sort of rays of sunshine, these evidences of truth in Christian teaching."

Visualizing light paths differentials (actually, ray footprint / spread in this case). These are used in path tracing to compute texture filtering, among other things... and are too easy to botch in corner cases, resulting in bugs and performance issues that are hard to pin back to the cause. Here I play with specular roughness of two parallel mirrors (the closest of which is made invisible to camera rays) to see how that affects the propagation of the light path footprint. I think it's pretty cool to see.

This box is so big it wouldn't even fit through the front door! From down the street right here in Tampa, it's Tampa Bay Rays! I've been a longtime fan of the Rays, and I will be at the game on Sunday to watch them play St. Louis! Thank you Coach Cash and crew for this box!
