    New Video, on deriving the SDF of a Line Segment. It's an introductory tutorial, but contains some useful info I think: I hope you enjoy it!

    LIVE stream coming up on February 5th at 11AM PST! I'll stream the development of a NEW shader based mathematical painting I started recently. Besides the Q&As, we'll talk about my creative process, the art direction, the coding and the maths! Link:

    How does one disable V-synch for Chrome? * I have my NVIDIA settings to "Use the 3D application setting" (checked other apps no longer do vsynch) * I start chrome with --disable-gpu-vsync * I tried both ANGLE and native GL (--use-gl=desktop) Still I'm always capped to 60 fps :(

    I kind-of accidentally found that f(x) = (2ˣ-1 - x·ln2)/(1-ln2) is a pretty good approximation for f(x)=x^2.2 that passes through 0 and 1, shares the derivative at 0 and _almost_ shares the derivative at 1. y = (exp2m1(x) - x*0.6931470)*3.258891;

    Dan Franke spent _two weeks_ painting this amazing Spiderverse tribute VR animation in Quill. (that's 1 person 14 days, not 1 month 14 people. Imagine what's going to happen the day the later is actually the case)

    Here's a wild prediction (because predicting incorrectly is kind of how predictions work) - by the end of the next decade, "Without Machine Learning" will be the "Organic" of computing and will be regarded in some areas of application as a sign of quality and trusty software.

    Triangle tiling. Or in micro-shader form, color=sign(fract(x+0.5*y)-fract(y))

    Super excited to announce my first VR story “The Remedy,” is released on Oculus TV!

    It took Goro two hours to make this, from scratch. If you are a film studio and are not using VR in your pipeline, you are wasting your time, energy and money.

    Articulating and texturing an SDF, which has been traditionally difficult. It's limited to torus shaped joints, but gives a correct SDF and provides solid UVW coordinates. Rigging, modeling and animation is basic/just for testing. Inspired by dr2's work.

    Idea for Android phones - when letting a user crop photos after the fact from their album, let them do it only in 8 pixel increments so you can just serialize the appropiate DCT blocks again without recompressing and damaging the image.

    Tomorrow I'll be streaming my 3rd LIVE Shader Deconstruction, at 11am Pacific time (2pm in the East Coast, 10pm in Europe, 5am in East Asia). I'll talk about modeling and lighting of the "Greek Temple" shader. This time it will be for Patreon supporters:

    I quickly tested the new sphere-noise with basic terrain generation. It's easy to setup to produce decent shapes (including concave areas). And since it is basically an SDF it renders at the speed of light of the raymarcher, without step reduction tweaks

    This is a (new?) type of noise that IS an SDF itself - it can be raymarched exactly without artifacts or small step sizes. It uses a grid of spheres of random sizes. You can combine different octaves with (smooth)minimum so FBM structures remain an SDF

    For the people asking, chances are they'll keep the recording public only to ACM members. But I'll ask whether I can take bits of it and edit a new video from them for my Youtube channel.

    "Why Do I Create Images with Mathematics" is the titl of my keynote at , Wed 20 at 9:30am. It's the story of a journey, and failures, successes, lessons, observations, realizations and conclusions. And pretty mathematical pictures. Maybe a little bit of live coding!

    New Video tutorial, on "Rounding Corners" in SDF modeling. It's introductory, but contains some pretty visuals: It got shared around a bit over this weekend, but I'm officially announcing it now nevertheless. Enjoy!

    The "Law of Conservation of Framerate" ensures that my new PC comes with a GPU that is 2x faster than the previous one, but also with 2x the screen resolution. (there's a similar Law of Conservation of Renderfarm Time for films that holds true for decades now thanks to artist's)
