shaded is a development tool for writing and previewing glsl fragment shaders,
in the spirit of:
Bring your own text editor.
Run your shader while you code, with hot reloading on save.
Share and reuse code with glslify:
#pragma glslify: noise = require('glsl-noise/simplex/2d') #pragma glslify: smoothUnion = require('./smoothUnion')
Built in uniforms (compatible with The Book of Shaders):
uniform vec2 u_resolution; uniform vec2 u_mouse; uniform float u_time;
Texture loading by comment:
uniform sampler2D bump; // ../textures/brick_wall.jpg
All of these features are available in atom-glsl-preview, but I switched from Atom to VSCode a while back, so I wanted to be able to write shaders in any text editor. vscode-glsl-canvas is pretty great, but doesn't support glslify or simple texture loading. Instead of tying myself to a particular editor, I decided to write a more generic tool that simply worked with my file system and a browser.
If you're coming from atom-glsl-preview, the behavior of
u_mouse has changed:
instead of providing normalized mouse coordinates (0 to 1),
u_mouse will match
the coordinates of
gl_FragCoord (divide by
u_resolution to get back to
normalized coordinates). This makes the behavior match that of The Book of
As in recent versions of atom-glsl-preview, no
precision specifiers or
uniform declarations will be added to your shader automatically—what you code is
what you get.
npm install --global shaded
yarn global add shaded
Start the server in the current directory:
$ shaded shaded listening at http://localhost:3000
Open http://localhost:3000 in your browser to see a listing of the files in the
current directory. Navigating to a file ending with the extension
open a page showing the shader in a WebGL canvas.
Start the build "watchers":
yarn run server-watch yarn run frontend-watch
Start the server (needs to be manually restarted after a change):
Open a browser to the examples: http://localhost:3000/examples
