Bitmasks for Behavior of Normals

Macro Definitions

	`kA3DTessFaceDataNormalSingle`
	`kA3DTessFaceDataNormalMask`

Detailed Description

group a3d_tessfacenormal

Bitmasks used to set and access the A3DTessFaceData::m_usUsedEntitiesFlags.

If this flag is set, the corresponding OneNormal entity (see Bitmasks for Specifying Tessellation Types) is planar and only one normal is defined for the entity. Otherwise, one normal per point is defined.
