Attribute() [2/4]

constexpr GrGeometryProcessor::Attribute::Attribute ( const char *  name, GrVertexAttribType  cpuType, SkSLType  gpuType  )

inlineconstexpr

Makes an attribute whose offset will be implicitly determined by the types and ordering of an array attributes.

Definition at line 75 of file GrGeometryProcessor.h.

Attribute() [3/4]

constexpr GrGeometryProcessor::Attribute::Attribute ( const char *  name, GrVertexAttribType  cpuType, SkSLType  gpuType, size_t  offset  )

inlineconstexpr

Makes an attribute with an explicit offset.

offset()

inline

Returns the offset if attributes were specified with explicit offsets. Otherwise, offsets (and total vertex stride) are implicitly determined from attribute order and types.
