Magnum::Shaders::TransformationUniform2D struct new in Git master
#include <Magnum/Shaders/Generic.h>

2D transformation uniform common for all shaders

Contains the per-draw transformation matrix.

Constructors, destructors, conversion operators

TransformationUniform2D(DefaultInitT = DefaultInit) explicit constexpr noexcept
Construct with default parameters.
TransformationUniform2D(NoInitT) explicit noexcept
Construct without initializing the contents.

Public variables

Matrix3x4 transformationMatrix
Transformation matrix.

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 setTransformationMatrix(const Matrix3& matrix) -> TransformationUniform2D&
Set the transformationMatrix field.

Function documentation

TransformationUniform2D& Magnum::Shaders::TransformationUniform2D::setTransformationMatrix(const Matrix3& matrix)

Set the transformationMatrix field.

Returns Reference to self (for method chaining)

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

Variable documentation

Matrix3x4 Magnum::Shaders::TransformationUniform2D::transformationMatrix

Transformation matrix.

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