• **new ShaderMixins**()

## Properties

### PI

▪ `Static` **PI**: `string`

---

### arcTan

▪ `Static` **arcTan**: `string`

Good atan that returns [0, 2Pi)

---

### blend

▪ `Static` **blend**: `string`

1 minus source alpha blend mode

---

### desaturate

▪ `Static` **desaturate**: `string`

---

### fade

▪ `Static` **fade**: `string`

Fade out the last `tail * 100` percent of `value` to 0 - a plateau with a steep dropoff

---

### hueShift

▪ `Static` **hueShift**: `string`

---

### invertBrightness

▪ `Static` **invertBrightness**: `string`

---

### invertColors

▪ `Static` **invertColors**: `string`

---

### mod2pi

▪ `Static` **mod2pi**: `string`

---

### modFloat

▪ `Static` **modFloat**: `string`

---

### noiseVec3

▪ `Static` **noiseVec3**: `string`

---

### perlin3

▪ `Static` **perlin3**: `string`

3d perlin noise - `cnoise(vec3)`, returns `[-1, 1]`
