This struct is a nested type of Struct HolovizOp::InputSpec.

struct View
Layer view.
By default a layer will fill the whole window. When using a view the layer can be placed freely within the window.
Layers can also be placed in 3D space by specifying a 3D transformation matrix. Note that for geometry layers there is a default matrix which allows coordinates in the range of [0 … 1] instead of the Vulkan [-1 … 1] range. When specifying a matrix for a geometry layer, this default matrix is overwritten.
When multiple views are specified the layer is drawn multiple times using the specified layer views.
It’s possible to specify a negative term for height, which flips the image. When using a negative height, one should also adjust the y value to point to the lower left corner of the viewport instead of the upper left corner.
Public Members
- float offset_x_ = 0.f
- float offset_y_ = 0.f
offset of top-left corner of the view. Top left coordinate of the window area is (0, 0) bottom right coordinate is (1, 1).
- float width_ = 1.f
- float height_ = 1.f
width and height of the view in normalized range. 1.0 is full size.
- std::optional<std::array<float, 16>> matrix_
row major 4x4 transform matrix (optional, can be nullptr)
