Member Function Documentation

[constexpr noexcept] QRhiVertexInputAttribute::QRhiVertexInputAttribute()

Constructs a default vertex input attribute description.

QRhiVertexInputAttribute::QRhiVertexInputAttribute(int binding, int location, QRhiVertexInputAttribute::Format format, quint32 offset, int matrixSlice = -1)

Constructs a vertex input attribute description with the specified binding number, location, format, and offset.

matrixSlice should be -1 except when this attribute corresponds to a row or column of a matrix (for example, a 4x4 matrix becomes 4 vec4s, consuming 4 consecutive vertex input locations), in which case it is the index of the row or column. location - matrixSlice must always be equal to the location for the first row or column of the unrolled matrix.

int QRhiVertexInputAttribute::binding() const

Returns the binding point index.

See also setBinding().

QRhiVertexInputAttribute::Format QRhiVertexInputAttribute::format() const

Returns the format of the vertex input element.

See also setFormat().

int QRhiVertexInputAttribute::location() const

Returns the location of the vertex input element.

See also setLocation().

int QRhiVertexInputAttribute::matrixSlice() const

Returns the matrix slice if the input element corresponds to a row or column of a matrix, or -1 if not relevant.

See also setMatrixSlice().

quint32 QRhiVertexInputAttribute::offset() const

Returns the byte offset for the input element.

See also setOffset().

void QRhiVertexInputAttribute::setBinding(int b)

Sets the binding point index to b. By default this is set to 0.

See also binding().

void QRhiVertexInputAttribute::setFormat(QRhiVertexInputAttribute::Format f)

Sets the format of the vertex input element to f. By default this is set to Float4.

See also format().

void QRhiVertexInputAttribute::setLocation(int loc)

Sets the location of the vertex input element to loc. By default this is set to 0.

See also location().

void QRhiVertexInputAttribute::setMatrixSlice(int slice)

Sets the matrix slice. By default this is set to -1, and should be set to a >= 0 value only when this attribute corresponds to a row or column of a matrix (for example, a 4x4 matrix becomes 4 vec4s, consuming 4 consecutive vertex input locations), in which case it is the index of the row or column. location - matrixSlice must always be equal to the location for the first row or column of the unrolled matrix.

See also matrixSlice().

void QRhiVertexInputAttribute::setOffset(quint32 ofs)

Sets the byte offset for the input element to ofs.

See also offset().
