HungryProton<p>If you're looking for a cheap way to break texture repetition (and keep the texture seamless), I got something for you <br><a href="https://mastodon.gamedev.place/tags/godotengine" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>godotengine</span></a> <a href="https://mastodon.gamedev.place/tags/shaders" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>shaders</span></a></p>
Filip Rachůnek<p>Hi everybody. It's still summer 2025, and to take a short break from further improvements to our raymarching shader, this time we'll create something really simple. We'll use the Voronoi algorithm, which we know from several previous tutorials, but we'll map it onto a sphere, so we’ll end up with something like a slightly strange planet or a dead star. <a href="https://mastodonczech.cz/tags/Godot" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Godot</span></a> <a href="https://mastodonczech.cz/tags/Godot4" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Godot4</span></a> <a href="https://mastodonczech.cz/tags/GodotEngine" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GodotEngine</span></a> <a href="https://mastodonczech.cz/tags/GodotTips" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GodotTips</span></a> <a href="https://mastodonczech.cz/tags/shaders" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>shaders</span></a> <a href="https://mastodonczech.cz/tags/devlog" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>devlog</span></a> <a href="https://mastodonczech.cz/tags/indiedev" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>indiedev</span></a> <br><a href="https://www.youtube.com/watch?v=Y34a4qQA0Ps" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="">youtube.com/watch?v=Y34a4qQA0Ps</span><span class="invisible"></span></a></p>

Steven Dollins<p>Tetrahedral symmetry requires that a general point be in a set of 12 -- on each of the 4 faces in each of 3 orientations. You can also add 4 points at the vertices, 4 at each face center, or 6 at each edge center. Combined, any even number of points &gt;= 4 can be arranged with tetrahedral symmetry, albeit not always evenly.</p><p>Here is 50 points in tetrahedral symmetry which requires that some of them have valence 7.</p><p><a href="https://genart.social/tags/AlgorithmicArt" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AlgorithmicArt</span></a> <a href="https://genart.social/tags/CreativeCoding" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CreativeCoding</span></a> <br><a href="https://genart.social/tags/Processing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Processing</span></a> <a href="https://genart.social/tags/glsl" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>glsl</span></a> <a href="https://genart.social/tags/shaders" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>shaders</span></a></p>

Steven Dollins<p>50 vertices arranged in D6 symmetry is interesting in that it forms two different but close in length triangle strips -- one following the longitudes and the other the latitudes.</p><p><a href="https://genart.social/tags/TilingTuesday" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>TilingTuesday</span></a><br><a href="https://genart.social/tags/AlgorithmicArt" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AlgorithmicArt</span></a> <a href="https://genart.social/tags/CreativeCoding" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CreativeCoding</span></a> <br><a href="https://genart.social/tags/Processing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Processing</span></a> <a href="https://genart.social/tags/glsl" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>glsl</span></a> <a href="https://genart.social/tags/shaders" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>shaders</span></a></p>
Steven Dollins<p>And 22 vertices can also arrange with 2-fold cylindrical symmetry that runs all the pentagons together into one long strip.
