Usage

In this page we'll explain the basic usage of VEDA.

Basic workflow

The workflow of livecoding with VEDA is like this:

1. Launch VEDA with Veda: Toggle
2. Run shaders with Veda: Load Shader (key: ctrl-enter)

So let's start coding!

First、 hit ctrl-shift-p (mac: cmd-shift-p) to open command palette.
When you type veda Atom will suggest Veda: Toggle.
Hit enter then VEDA will show the result of default shader:

Next, let's create a new GLSL file.
Create new file with ctrl-n (mac: cmd-n) and save as myshader.frag.

Paste this code to the file:

precision mediump float;
uniform float time;
uniform vec2 mouse;
uniform vec2 resolution;

void main(void) {
  vec2 position = (gl_FragCoord.xy / resolution.xy) + mouse / 4.0;

  float color = 0.0;
  color += sin(position.x * cos(time / 15.0) * 80.0) + cos(position.y * cos(time / 15.0) * 10.0);
  color += sin(position.y * sin( time / 10.0) * 40.0) + cos(position.x * sin(time / 25.0) * 40.0);
  color += sin(position.x * sin( time / 5.0) * 10.0) + sin(position.y * sin(time / 35.0) * 80.0);
  color *= sin(time / 10.0) * 0.5;

  gl_FragColor = vec4(vec3(color, color * 0.5, sin(color + time / 3.0) * 0.75), 1.0);
}

(As you may notice, this is the default code of GLSL Sandbox!)

...then hit ctrl-enter.
VEDA will evaluate myshader.frag and show the result:

Congratulations!!
Now you can edit the code and see the result with ctrl-enter.

You've started the first step as a live coder!!
