| I haven't looked around a lot, but does anyone know what Inigo's
| video production process & tools are? He's got a lot of shots in
| the video I'm not sure how I'd make, and I've love to know how
| much custom software he's writing just for the video making.
|
| I've tried painting with maths as he likes calling it, on
| ShaderToy... for many hundreds of hours. It's always more
| difficult both technically and artistically to get the image in
| my head to show up on screen. Sometimes I wonder if I need to
| allow things to happen more organically, to try things and run
| with whatever works, but I rarely work that way. Maybe sticking
| too closely to something I have in mind in advance makes me aim
| for unrealistic looks that SDFs aren't good at. Or maybe I'm just
| not trying hard enough. I don't know. Inigo makes it looks easy
| though.
|
| Another thing that's really fun to do is deconstruct his shaders
| piece by piece, or unpaint the character. It's very enlightening
| in a different way than his construction videos. I've done this
| for the shader in the video here, as well as a few of his other
| shaders, and I always learn things. It always strikes me how
| close to the edge of the illusion his shaders are, how well they
| play to the camera and how quickly they look bad with tiny
| changes. It's a master class in efficiency of design.

| also uses some aftereffects to put it together.

| If I remember right I think he mentioned somewhere on Twitter

| cool

| percentage of programmers has this level of artistic fluency.
| dahart wrote:
| Absolutely and without question. I'd argue he surpasses the
| normal meanings behind 10x, and is one of the super-rare people
| up in the stratosphere. Not because of the code itself (though
| his combination of math, code, and art skills are 10x on their
| own), but more because of his goals and it's effects on other
| people. Inigo Quilez is one of the most famous demo scene
| programmers, one of the authors of ShaderToy, has one of the
| best sets of graphics programming articles on the net
| (https://iquilezles.org/articles/) and he has been focused on
| sharing ideas and getting other people to share ideas. His
| level of knowledge and code influence on other people, if you
| tried to measure it, which you can't, but it would be more than
| thousands of times more productive than a single programmer.

| If you're interested in learning to create these types of

|
| https://shaderpark.com
|
| It's specifically designed to make the methods Inigo is demoing
| in this video easier to use!
|
| There are a couple initial tutorials as well
