Detailed Description

Vertex fetch instruction of 3 dwords.

Member Function Documentation

GetExpAdjust()

int rex::xenos::ucode::VertexFetchInstruction::GetExpAdjust ( ) const

inline

Returns the exponent adjustment, [-32, 31].

GetFetchConstantIndex()

u32 rex::xenos::ucode::VertexFetchInstruction::GetFetchConstantIndex ( ) const

inline

Returns the vertex fetch constant index [0-95]. Valid only for vfetch_full.

GetOffset()

i32 rex::xenos::ucode::VertexFetchInstruction::GetOffset ( ) const

inline

Returns the dword offset, [-4194304, 4194303].

GetPredicateCondition()

bool rex::xenos::ucode::VertexFetchInstruction::GetPredicateCondition ( ) const

inline

Returns the predicate value that enables the instruction.

GetPrefetchCount()

u32 rex::xenos::ucode::VertexFetchInstruction::GetPrefetchCount ( ) const

inline

Returns the prefetch count, 1 less than the number of vertices.

GetSrcReg()

u32 rex::xenos::ucode::VertexFetchInstruction::GetSrcReg ( ) const

inline

Returns the source register index. Valid only for vfetch_full.

GetStride()

u32 rex::xenos::ucode::VertexFetchInstruction::GetStride ( ) const

inline

Returns the dword stride, [0, 255]. Valid only for vfetch_full.

IsIndexRounded()

bool rex::xenos::ucode::VertexFetchInstruction::IsIndexRounded ( ) const

inline

Reports whether the index is rounded as floor(index + 0.5) rather than floored.

IsMiniFetch()

bool rex::xenos::ucode::VertexFetchInstruction::IsMiniFetch ( ) const

inline

Reports whether the instruction is vfetch_mini rather than vfetch_full.

IsNormalized()

bool rex::xenos::ucode::VertexFetchInstruction::IsNormalized ( ) const

inline

Reports whether the data is normalized rather than integer.
