ludus::graphics::renderer::OverlayVertex¶

Struct

One generic overlay vertex, independent of fonts and native GPU objects.

#include <ludus/graphics/renderer/overlays.hpp>

struct ludus::graphics::renderer::OverlayVertex final

Fields¶

foundation::math::Vector4 ludus::graphics::renderer::OverlayVertex::Clip

Homogeneous canonical clip position; W must be positive, Z in [0,W].

foundation::math::Vector4 ludus::graphics::renderer::OverlayVertex::Coverage

Top-left normalized atlas UV; Z is 0 for solid geometry or 1 for coverage.

foundation::math::Vector4 ludus::graphics::renderer::OverlayVertex::Color {1, 1, 1, 1}

Straight linear display RGBA in [0,1]; shader premultiplies after coverage.
