Magnum::Shaders::MeshVisualizerDrawUniform3D struct new in Git master

Per-draw uniform for 3D mesh visualizer shaders.

Together with the generic TransformationUniform3D contains parameters that are specific to each draw call. Material-related properties are expected to be shared among multiple draw calls and thus are provided in a separate MeshVisualizerMaterialUniform structure, referenced by materialId.

Constructors, destructors, conversion operators

MeshVisualizerDrawUniform3D(DefaultInitT = DefaultInit) explicit constexpr noexcept
Construct with default parameters.
MeshVisualizerDrawUniform3D(NoInitT) explicit noexcept
Construct without initializing the contents.

Public variables

Matrix3x4 normalMatrix
Normal matrix.
UnsignedShort materialId
Material ID.

Convenience setters

Provided to allow the use of method chaining for populating a structure in a single expression, otherwise equivalent to accessing the fields directly. Also guaranteed to provide backwards compatibility when packing of the actual fields changes.

auto setNormalMatrix(const Matrix3x3& matrix) -> MeshVisualizerDrawUniform3D&
Set the normalMatrix field.
auto setMaterialId(UnsignedInt id) -> MeshVisualizerDrawUniform3D&
Set the materialId field.

Function documentation

MeshVisualizerDrawUniform3D& Magnum::Shaders::MeshVisualizerDrawUniform3D::setNormalMatrix(const Matrix3x3& matrix)

Set the normalMatrix field.

Returns Reference to self (for method chaining)

The matrix is expanded to Matrix3x4, with the bottom row being zeros.

MeshVisualizerDrawUniform3D& Magnum::Shaders::MeshVisualizerDrawUniform3D::setMaterialId(UnsignedInt id)

Set the materialId field.

Returns Reference to self (for method chaining)

Variable documentation

Matrix3x4 Magnum::Shaders::MeshVisualizerDrawUniform3D::normalMatrix

Normal matrix.

Default value is an identity matrix. The bottom row is unused and acts only as a padding to match uniform buffer packing rules.

UnsignedShort Magnum::Shaders::MeshVisualizerDrawUniform3D::materialId

Material ID.

References a particular material from a MeshVisualizerMaterialUniform array. Useful when an UBO with more than one material is supplied or in a multi-draw scenario. Should be less than the material count passed to MeshVisualizerGL2D / MeshVisualizerGL3D constructor. Default value is 0, meaning the first material gets used.
