# BlendEquation

Scene/BlendEquation.js 8
Determines how two pixels' values are combined.

##### Properties:

Name | Type | Description
--- | --- | ---
`ADD` | Number | Pixel values are added componentwise. This is used in additive blending for translucency.
`SUBTRACT` | Number | Pixel values are subtracted componentwise (source - destination). This is used in alpha blending for translucency.
`REVERSE_SUBTRACT` | Number | Pixel values are subtracted componentwise (destination - source).
`MIN` | Number | Pixel values are given to the minimum function (min(source, destination)). This equation operates on each pixel color component.
`MAX` | Number | Pixel values are given to the maximum function (max(source, destination)). This equation operates on each pixel color component.
