# Bitangent

The geometric bitangent vector of the currently-processed data in a given coordinate space.

## Parameter Types

Parameter Types Parameter descriptions Discussion Valid values for the Space parameter include: model: The local coordinate space before the shader applies any local deformations or global transforms to the geometry. object: The local coordinate space after the shader applies local deformations, but before it applies global transforms to the geometry. world: The global coordinate space after the shader applies both local deformations and global transforms to the geometry.
