<h2>GLSL Std140 and Std430 Layout Calculator</h2>
<a href="https://jackjamison.net">by Jack Jamison</a>

<br>
<div>
<textarea rows=20 cols=25 id="input"></textarea>
<textarea rows=20 cols=40 id="output" readOnly=true></textarea>
<br>
<select id="version_select" options=["one"]>
<option value="std140" selected>Std 140</option>
<option value="std430">Std 430</option>
</select><br>
</div>
<h2>Instructions</h2>
<p>Write your declarations on the left, get your output on the right. For the most part, you can paste in GLSL code.<br><br>
You can define structs and uniform blocks with the syntax "#uniform <b>name</b>" or "#struct <b>name</b>".</p>
<h2>About</h2>
<p>This tool was made because tons of resources online about GLSL alignment are wrong, such as <a href="https://ptgmedia.pearsoncmg.com/images/9780321552624/downloads/0321552628_AppL.pdf">this one</a>.</p>
<a href="https://registry.khronos.org/OpenGL/specs/gl/glspec46.core.pdf">For detailed rules, read the OpenGL spec, pages 146-147</a><br>
