Microfractal<a href="https://mathstodon.xyz/tags/Fractalfriday" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Fractalfriday</a> I updated my <a href="https://mathstodon.xyz/tags/Shadertoy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Shadertoy</a> <a href="https://mathstodon.xyz/tags/fractal" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fractal</a> explorer. Link: <a href="https://www.shadertoy.com/view/33sSRf" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.shadertoy.com/view/33sSRf</a> It now supports skewing the C-plane using a quad of four draggable points. The coefficients 'a' and 'b' can now also changed by the mouse. To show the points, simply hold the space bar.Here is a video which demonstrates that. The formula is \(z_{n+1}=z_n^2*\frac{z_n-a}{z_n-b}+c\) where a and b are the blue points in the video.<a href="https://mathstodon.xyz/tags/Mathart" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Mathart</a> <a href="https://mathstodon.xyz/tags/GLSL" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GLSL</a> <a href="https://mathstodon.xyz/tags/Mandelbrot" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Mandelbrot</a> <a href="https://mathstodon.xyz/tags/creativecoding" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#creativecoding</a>

bµgSo I was making a random 2d map in <a href="https://fosstodon.org/tags/shadertoy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#shadertoy</a>, and I was trying to understand the effect of the rotation of the coordinate in a fbm 2d <a href="https://fosstodon.org/tags/noise" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#noise</a> loop, so I plugged the mouse coordinates onto the rotation angle and started to play with it to see what it did.To my surprise, it felt like a "fire" effect, directed in one direction or the other. I feel like this could really be used to make an actual fire effect, though I'm not sure if I'm doing the rotation right at the moment...<a href="https://fosstodon.org/tags/glsl" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#glsl</a> <a href="https://fosstodon.org/tags/demo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#demo</a>

bµgSo here is what the length of the derivatives look like on a 3D noise. I'm starting to see why it's useful for emulating terrain erosion ️⛰️<a href="https://fosstodon.org/tags/shadertoy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#shadertoy</a> <a href="https://fosstodon.org/tags/glsl" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#glsl</a> <a href="https://fosstodon.org/tags/noise" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#noise</a>

bµgTook me several days (including so many checks like manual unrolling), but here are the 3d gradient noise derivatives¹ from iquilezles expressed with mix instead of unrolled.Reason I did that? Well let's pretend it's for clarity and numerical stability (it's all a lie, I was just trying to understand wth was going on here).¹ <a href="https://iquilezles.org/articles/gradientnoise/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://iquilezles.org/articles/gradientnoise/</a><a href="https://fosstodon.org/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a> <a href="https://fosstodon.org/tags/glsl" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#glsl</a> <a href="https://fosstodon.org/tags/shadertoy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#shadertoy</a>

Keenan CraneAfter trying several broken repos/scripts, I made a Python script for rendering <a href="https://mathstodon.xyz/tags/ShaderToy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ShaderToy</a> shaders to antialiased video (or rather, image sequences):<a href="https://github.com/keenancrane/ShaderDump" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/keenancrane/ShaderDump</a>(This one will surely be broken too someday, but for now it works nicely 😛)

Andrea BinelloHi, recently, I started studying and developing simple <a href="https://techhub.social/tags/GLSL" class="mention hashtag" rel="tag">#GLSL</a> <a href="https://techhub.social/tags/shaders" class="mention hashtag" rel="tag">#shaders</a>, “fragment shaders”, to be precise. I discovered there are various little platforms like <a href="https://www.shadertoy.com" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://www.shadertoy.com</a> but also the less-known <a href="https://oneshader.net" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://oneshader.net</a> (and even <a href="https://editor.thebookofshaders.com" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://editor.thebookofshaders.com</a>) where it’s possible to develop and share “toy” shaders without the need to have ultra-advanced skills on OpenGL, WebGL, etc.Developing these shaders is a fun (really entertaining!) activity that nicely combines <a href="https://techhub.social/tags/programming" class="mention hashtag" rel="tag">#programming</a>, <a href="https://techhub.social/tags/math" class="mention hashtag" rel="tag">#math</a>, and <a href="https://techhub.social/tags/graphics" class="mention hashtag" rel="tag">#graphics</a>. I have already made some shaders on Shadertoy, which you can see here:➡️ <a href="https://www.shadertoy.com/user/andbin" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://www.shadertoy.com/user/andbin</a>At this time, I am unable to develop very sophisticated/stunning shaders. Anyway, my actual shaders seem nice and pleasant. Feel free to comment here (or on Shadertoy) if you like my shaders. Clearly, I am still at the beginning!
