Magnum::Shaders::MeshVisualizerDrawUniform2D struct new in Git master

Per-draw uniform for 2D mesh visualizer shaders.

Together with the generic TransformationProjectionUniform2D 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

MeshVisualizerDrawUniform2D(DefaultInitT = DefaultInit) explicit constexpr noexcept
Construct with default parameters.
MeshVisualizerDrawUniform2D(NoInitT) explicit noexcept
Construct without initializing the contents.

Public variables

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 setMaterialId(UnsignedInt id) -> MeshVisualizerDrawUniform2D&
Set the materialId field.

Function documentation

MeshVisualizerDrawUniform2D& Magnum::Shaders::MeshVisualizerDrawUniform2D::setMaterialId(UnsignedInt id)

Set the materialId field.

Returns Reference to self (for method chaining)

Variable documentation

UnsignedShort Magnum::Shaders::MeshVisualizerDrawUniform2D::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 the MeshVisualizerGL2D::MeshVisualizerGL2D(Flags, UnsignedInt, UnsignedInt) / MeshVisualizerGL3D::MeshVisualizerGL3D(Flags, UnsignedInt, UnsignedInt) constructor, if material count is 1, this field is assumed to be 0 and isn't even read by the shader. Default value is 0, meaning the first material gets used.
