Detailed Description

Render pipeline and draw pass for the transparency checkerboard (fullscreen triangle).

Variable Documentation

kTransparencyCheckerboardCellLogicalPx

double donner::geode::kTransparencyCheckerboardCellLogicalPx = 16.0

inlineconstexpr

Appearance of the transparency checkerboard drawn behind see-through document pixels.

Shared by every presentation path so the same document lands on identical cells. The size is in logical pixels, so the pattern is anchored to device pixels and never scales with document zoom.

kTransparencyCheckerboardDarkColor

std::array<float, 4> donner::geode::kTransparencyCheckerboardDarkColor

inlineconstexpr

Initial value:

= {
    40.0f / 255.0f, 40.0f / 255.0f, 40.0f / 255.0f, 1.0f}

RGBA in the 0-1 range for odd cells.

kTransparencyCheckerboardLightColor

std::array<float, 4> donner::geode::kTransparencyCheckerboardLightColor

inlineconstexpr

Initial value:

= {
    60.0f / 255.0f, 60.0f / 255.0f, 60.0f / 255.0f, 1.0f}

RGBA in the 0-1 range for even cells.
