QSSGGltfAccessorReader Namespace Reference

Functions
QByteArray	readPacked (const QSSGGltfDocument &document, int accessorIndex)
QList< float >	readAsFloats (const QSSGGltfDocument &document, int accessorIndex)
QList< quint32 >	readIndices (const QSSGGltfDocument &document, int accessorIndex)

Detailed Description

Typed access to glTF accessor data. All functions compose the buffer view byte stride (interleaved data), the accessor byte offset, and sparse substitution, and return tightly packed copies. An accessor without a buffer view yields zeros, as the specification requires.

Function Documentation

readAsFloats()

QList< float > QSSGGltfAccessorReader::readAsFloats	(	const QSSGGltfDocument &	document,
		int	accessorIndex )

Returns the element data of accessor accessorIndex in document, converted to floats, accessor.componentCount() per element. Normalized integer component types are dequantized as the specification describes (c/255, max(c/127, -1), ...), which also covers accessors quantized per KHR_mesh_quantization; non-normalized integers are cast.

readIndices()

QList< quint32 > QSSGGltfAccessorReader::readIndices	(	const QSSGGltfDocument &	document,
		int	accessorIndex )

Returns the scalar index data of accessor accessorIndex in document, widened to 32-bit unsigned integers.

readPacked()

QByteArray QSSGGltfAccessorReader::readPacked	(	const QSSGGltfDocument &	document,
		int	accessorIndex )

Returns the element data of accessor accessorIndex in document, packed to accessor.elementByteSize() per element.
