Member Data Documentation

◆ alpha

float KIGFX::LAYER_RANGE::alpha = 1.0f

Compositing alpha.

Below 1 the layer goes through a temp FBO, and a layer of mixed alpha keeps 1 with per-instance alpha.

Definition at line 179 of file frame_packet.h.

Referenced by KIGFX::GAL_MODERN::Flush(), NeedsTempFBO(), and KIGFX::RENDER_THREAD::RenderGeometryInto().

◆ bitmapCount

uint32_t KIGFX::LAYER_RANGE::bitmapCount = 0

Definition at line 200 of file frame_packet.h.

Referenced by KIGFX::GAL_MODERN::Flush(), HasGeometry(), KIGFX::RENDER_THREAD::RenderGeometryInto(), and KIGFX::RhiRangeReaches().

◆ bitmapStart

uint32_t KIGFX::LAYER_RANGE::bitmapStart = 0

Definition at line 199 of file frame_packet.h.

Referenced by KIGFX::GAL_MODERN::Flush(), and KIGFX::RENDER_THREAD::RenderGeometryInto().

◆ buffer

std::array<RHI_BufferHandle, RHI_SHAPES> KIGFX::LAYER_RANGE::buffer

Buffers a retained scene layer owns per shape.

A null handle indexes the draw descriptor's buffer.

◆ count

RHI_SHAPE_COUNTS KIGFX::LAYER_RANGE::count {}

Definition at line 195 of file frame_packet.h.

Referenced by KIGFX::GAL_MODERN::Flush(), HasGeometry(), and KIGFX::RhiRangeReaches().

◆ cullRuns

std::shared_ptr<const RHI_RUN_TABLE> KIGFX::LAYER_RANGE::cullRuns

Bounds of the range's buffers so off-screen runs are skipped.

Null draws everything.

Definition at line 244 of file frame_packet.h.

◆ depth

float KIGFX::LAYER_RANGE::depth = 0.0f

Definition at line 173 of file frame_packet.h.

Referenced by KIGFX::GAL_MODERN::appendSceneRanges(), KIGFX::GAL_MODERN::beginLayerRange(), and KIGFX::GAL_MODERN::Flush().

◆ depthFar

float KIGFX::LAYER_RANGE::depthFar = 1.0f

Definition at line 213 of file frame_packet.h.

Referenced by KIGFX::RENDER_THREAD::RenderGeometryInto().

◆ depthKnockout

bool KIGFX::LAYER_RANGE::depthKnockout = false

Definition at line 220 of file frame_packet.h.

Referenced by KIGFX::GAL_MODERN::Flush(), NeedsTempFBO(), and KIGFX::RENDER_THREAD::RenderGeometryInto().

◆ depthNear

float KIGFX::LAYER_RANGE::depthNear = 0.0f

Depth slice the range is drawn into.

Retained layers store relative depth so reordering layers rewrites no geometry, and the default keeps the elements' own depth.

Definition at line 212 of file frame_packet.h.

Referenced by KIGFX::RENDER_THREAD::RenderGeometryInto().

◆ difference

bool KIGFX::LAYER_RANGE::difference = false

A diff layer (GAL::StartDiffLayer) that replaces what is under it with the colour difference, as gerbview's XOR mode needs.

◆ hasNegatives

bool KIGFX::LAYER_RANGE::hasNegatives = false

Subtractive instances go through a temp FBO so their erasure stays within the layer.

uint32_t KIGFX::LAYER_RANGE::runCount = 0

Referenced by KIGFX::GAL_MODERN::Flush().

◆ runStart

uint32_t KIGFX::LAYER_RANGE::runStart = 0
