ludus::graphics::renderer::ViewMapping¶

Struct

Copied mapping shared by draw preparation and pointer conversion; no GPU ownership.

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

struct ludus::graphics::renderer::ViewMapping final

Fields¶

ludus::foundation::uint32 ludus::graphics::renderer::ViewMapping::DrawableWidth = 0

Actual drawable width against which the mapping was resolved.

ludus::foundation::uint32 ludus::graphics::renderer::ViewMapping::DrawableHeight = 0

Actual drawable height against which the mapping was resolved.

rhi::RasterRectangle ludus::graphics::renderer::ViewMapping::Region {}

Physical region owned by this view, clipped to the actual drawable.

rhi::RasterRectangle ludus::graphics::renderer::ViewMapping::Viewport {}

Rounded drawing rectangle; Fill uses Region and clips through ClipTransform.

ludus::foundation::math::Vector2 ludus::graphics::renderer::ViewMapping::Origin {}

Physical pixel-edge origin of logical (0,0), including crop/letterbox offsets.

ludus::foundation::math::Vector2 ludus::graphics::renderer::ViewMapping::Scale {}

Physical pixels per logical unit, derived from the rounded content rectangle.

VirtualScreen ludus::graphics::renderer::ViewMapping::Screen {}

Validated authored dimensions.

ludus::foundation::math::Matrix4 ludus::graphics::renderer::ViewMapping::ClipTransform = ludus::foundation::math::Matrix4::Identity()

Apply to canonical clip coordinates before rasterization; Fill expands for cropping.

bool ludus::graphics::renderer::ViewMapping::FractionalFallback = false

True only when IntegerFit could not fit a whole-number scale.
