## Uniform
Uniform variable qualifier.
### Declaration / Example
### Parameters
### Example
```glsl
uniform vec4 direction;
```
### Description
```uniform``` variables contain read-only data shared from WebGL/OpenGL environment to a vertex or fragment shader.
The value is per primitive, so is useful for variables which remain constant along a primitive, frame or scene.

## Varying
Varying variable qualifier.
### Declaration / Example
### Parameters
### Example
```glsl
varying vec3 position;
```
### Description
```varying``` variables contain data shared from a vertex shader to a fragment shader.
The variable must be written in the vertex shader and the read-only value in the fragment shader is then interpolated from the vertices which make up the fragment.
