glsl-canvas installs statistics

💎 vscode-glsl-canvas

The extension opens a live WebGL preview of GLSL shaders within VSCode by providing a command.

It use glsl-canvas a modified and improved version of glslCanvas javascript library from Book of Shaders and glslEditor made by Patricio Gonzalez Vivo.

*Now supporting WebGL2. just add #version 300 es at the very start of the file.*

*Now supporting nested includes with relative paths.*

*Optimized video recording options, with record size and duration. Choose between MediaRecorderApi or CCapture for high quality compression.*

*Run ⌘ ⇧ P on mac os, ctrl ⇧ P on windows.* *Then type command to display a fullscreen preview of your fragment shader.*

Features

• Both supports WebGL and WebGL2. Automatically create WebGL2 context by adding #version 300 es as the first line of file. • Integrated support of error handling with lines hilight. • Drawing modes: , , , and with default mesh. • Mesh loader and parser for format. • Vertex in fragment with macro. • Multiple buffers with macro. • Play / pause functionality. • Recording and exporting to video with resolution and duration settings, using or for high quality video. • Activable stats.js performance monitor. • Custom uniforms. • Activable gui for changing custom uniforms at runtime. • Export to html page with live reload. • Glsl code formatter standard and compact mode. • Glsl Snippets.

Attributes

Uniforms

The uniforms provided are , , , and .

WebGL Extensions

You can include any supported WebGL extension through the array option modifying the workspace's file.

You can then enable the extension in the shader

WebGL2

For WebGL2 context creation just add #version 300 es at the very start of the file.

*no other characters allowed before macro!*

IO Buffers

You can use shader buffers by requiring definition with #ifdef or defined directly in .glsl code. Just ask for BUFFER_N definition and a u_bufferN uniform will be created for you:

Playground

Textures

You can define the texture channels (, , ...) by modifying the workspace's file.

*As of today VSCode do not support video element or audio element. You can use video texture with the Export to html feature.*

u_camera

is a vec3 array with coordinates for an orbital camera positioned at world zero, useful for raymarching.

Playground

u_trails[10]

is a vec2 array with stored inertia mouse positions for mouse trailing effects.

Playground

Custom Uniforms

You can also define custom uniforms by modifying the workspace's file.

Types supported are , , and . Vectors structures are converted from arrays of floats. Range values goes from to .

| Type | Property |

| float | "u_float": 1.0, | | vec2 | "u_vec2": [1.0, 1.0], | | vec3 | "u_vec3": [1.0, 1.0, 1.0], | | vec4 | "u_vec4": [1.0, 1.0, 1.0, 1.0], |

Uniforms Gui

By clicking the option button you can view and modify at runtime uniforms via the dat.gui interface.

Export to html

You can export your shader, assets and uniforms to an html page with livereload for testing in browser.

Color Picker

Waiting for a more customizable code inset feature, and arrays can be modified with the integrated color picker.

Including dependent files with #include

You can now include other GLSL code using a traditional #include "file.glsl" macro.

Antialias

Enables or disables antialias in the WebGL context.

Change detection

You can set the timeout change detection option by modifying the workspace's file.

Refresh on save

Enables or disables refreshing the glslCanvas when saving the document.

Refresh on change

Enables or disables refreshing the glslCanvas when changing the document.

Use formatter

Enables or disables glsl code formatter.

Use compact formatter

Enables or disables glsl code formatter compact mode.

Install on export

Enables or disables installing the Npm packages on export.

Record duration

Specify automatic recording duration in seconds. Set to to disable this feature.

Record width

Specify canvas recording width in pixels. Default value is .

Record height

Specify canvas recording height in pixels. Default value is .

Fragment shader

An example of fragment shader. You can copy paste this code in an empty .glsl file:
