const

Hash()

const ON_SHA1_Hash ON_MappingTag::Hash

(

)

const

Returns: A sha1 hash the identifies the mapping tag.

IsDefaultSurfaceParameterMapping()

bool ON_MappingTag::IsDefaultSurfaceParameterMapping

(

)

const

Returns: True if the mapping tag is for a mapping with type ON_TextureMapping::srfp_mapping with m_uvw = identity.

IsSet()

(

)

const

Returns: True if the mapping tag is set.

Read()

bool ON_MappingTag::Read

(

(

const ON_TextureMapping &

mapping

)

SetDefaultSurfaceParameterMappingTag()

Member Data Documentation

m_mapping_crc

ON__UINT32 ON_MappingTag::m_mapping_crc = 0

ON_TextureMapping::MappingCRC() (from decades ago - a sha1 would be better when SDK can break)

m_mapping_id

ON_UUID ON_MappingTag::m_mapping_id = ON_nil_uuid

ON_TextureMapping::m_mapping_id.

Identifies the mapping used to create the texture coordinates and records transformations applied to the mesh after the texture coordinates were calculated. If the texture mapping does not change when the mesh is transformed, then set m_mesh_xform to zero so that compares will work right.

m_mapping_type

ON_TextureMapping::TYPE ON_MappingTag::m_mapping_type = ON_TextureMapping::TYPE::no_mapping

ON_TextureMapping::m_type.

m_mesh_xform

ON_Xform ON_MappingTag::m_mesh_xform = ON_Xform::IdentityTransformation

SurfaceParameterMapping

const ON_MappingTag ON_MappingTag::SurfaceParameterMapping

Unset

const ON_MappingTag ON_MappingTag::Unset
