Detailed Description

Utility functions for encoding and decoding mesh vertex attributes.

Provides conversion between high-level types (ezVec3, ezColor, etc.) and various GPU buffer formats. Handles normals, tangents, texture coordinates, bone weights, and vertex colors with optional color space conversion.

EncodeTangent()

EZ_ALWAYS_INLINE ezResult ezMeshBufferUtils::EncodeTangent ( const ezVec3 &  vTangent, float  fTangentSign, ezByteArrayPtr  dest, ezGALResourceFormat::Enum  destFormat  )

static

Encodes a tangent vector and bitangent sign to the specified GPU buffer format.

The tangent sign is typically used to reconstruct the bitangent in the shader.
