Common PFX in Hexels include blur and color adjustment. PFX are similar to filters in Photoshop in that they modify an existing image according to a set of rules. Post-processing (PFX) shaders will be used for our two examples. Final compositing of glow onto the Hexels imageД¬urrently, three of these stagesвЂ“PFX, layer compositing (blend), and baked color adjustmentвЂ“support selection of shaders, including custom shaders supplied by the user.Post-processing effects applied to each layer.Drawing shapes and calculating low-level effects like halftone and texturing.Hexels incorporates shaders into every stage of its drawing pipeline:.For Hexels users, this allows people to create their own blending modes and PFX, potentially doing things with Hexels that we at Marmoset never dreamed of.

For developers, this is useful because code changes can be seen immediately without having to recompile and re-run. Another important feature of shaders is that they can be loaded and reloaded while the application is running.

Shaders run on the GPU far faster than compiled code runs on the CPU, which means that post effects can be re-calculated every time Hexels draws without causing a noticeable slowdown. What is a Shader?ДЄ fragment shader is a short program that runs on the graphics card (GPU) to determine the color of an individual pixel. Please note that as we improve Hexels, this information may change, and any shaders you make may need to be updated for future versions, but weвЂ™ll try to keep as much backwards compatibility as possible. A basic knowledge of GLSL 1.2 (OpenGL Shading Language) is highly recommended, but anyone with some programming experience should be able to do something with this tutorial. This tutorial gives an overview of shaders and how theyвЂ™re used in Hexels, and then shows a couple simple examples of adding custom shaders, allowing Hexels to perform new tricks. Shaders allow these effects to be calculated in real-time for HexelsвЂ™ vector graphics. One of the coolest new features in Hexels 2.5 is the use of fragment shaders for layer blending and post effects (PFX). IвЂ™ve posted it here because weвЂ™re currently in the middle of transitioning to a new website, and this tutorial hasnвЂ™t made its way over yet. Note: This is a re-post of my Shaders tutorial from the Marmoset website. You could even draw aВ picture there! (This is a flower and grass and a sun.) HexelsД¬ustom Shaders in Hexels Adding Your Own Blending and Post-Processing Effects So next time you fire up Hexels, take a new look at that plain-looking empty grid. yellow, black, and chocolate), so all your bases should be covered. Hexels 2.55 even added support for importing Lab color (i.e.

aco palettes from Photoshop as well as export back to the format. Gradients can quickly populate an entire grid of colors. Behold! The Hexels palette lets you create gradients in RGB or HSV color space.Д¬reating vertical gradients between the two takes just a few seconds and gives us a nice color selection. Click the little gear icon at the lower right of the palette and you can select HSV gradients. Hexels will even create multi-color gradients that hit every color it finds along the way. The layout of your palette can help you keep track of whatвЂ™s what.ДЄutomatic Gradients Drag and drop a color onto another to create gradients!ДoВ you find it somewhat tedious to carefully pick eight evenly spaced colors between salmon and magenta? Then we have the solution for you! Hexels allows you to create gradients right on the color palette by dropping one existing color onto another color in the same row or column. Double-click again to edit the new color swatch. Or you can double-click to add the currently selected color anywhere you want. Colors can be dragged and dropped anywhere on the palette, and even copied if you hold alt. While Hexels canвЂ™t tell you where you put your keys or what time dinner is, its palette can helpВ you organize your mind. вЂњOrganize your mind, organize your life.вЂќ Although it looks deceptively like a plain old list of colors, the color palette in Hexels 2 has got a few tricks up its sleeve.
