Gfx::GeometryViewer::SceneDrawer Class Reference

Inheritance diagram for Gfx::GeometryViewer::SceneDrawer:

Detailed Description

Draws every primitive of a scene with its world transform, in the shading modes of the Geometry viewer, and the lights and cameras of the scene as line gizmos. Part of the viewer's renderer, on the render thread.

The scene is walked when it changes, not every frame. A mesh is uploaded once, and kept for as long as the buffers of its primitive stay the same: a scene whose transforms only move does not upload anything again.

Member Function Documentation

active()

bool Gfx::GeometryViewer::SceneDrawer::active ( ) const

inlineoverridevirtualnoexcept

The scene needs more than the single geometry the renderer draws on its own: several primitives, transforms, lights or cameras

Implements score::gfx::ModelSceneDrawer.

bounds()

const ossia::aabb & Gfx::GeometryViewer::SceneDrawer::bounds ( ) const

inlineoverridevirtualnoexcept

The bounds of what is drawn, in the space of the scene.

Implements score::gfx::ModelSceneDrawer.

draw()

void Gfx::GeometryViewer::SceneDrawer::draw ( score::gfx::RenderList &  renderer, QRhiCommandBuffer &  cb, score::gfx::Edge &  edge  )

overridevirtual

Implements score::gfx::ModelSceneDrawer.

drawLines()

void Gfx::GeometryViewer::SceneDrawer::drawLines ( score::gfx::RenderList &  renderer, QRhiCommandBuffer &  cb, score::gfx::Edge &  edge, QRhiGraphicsPipeline *  lines, QRhiShaderResourceBindings *  srb  )

overridevirtual

With the line pipeline of the guides: world-space positions and colours.

Implements score::gfx::ModelSceneDrawer.

hasLines()

bool Gfx::GeometryViewer::SceneDrawer::hasLines ( ) const

inlineoverridevirtualnoexcept

The gizmos and the outline of the selected object.

Implements score::gfx::ModelSceneDrawer.

release()

void Gfx::GeometryViewer::SceneDrawer::release ( )

overridevirtual

The GPU resources go away, the scene stays: the next update uploads it again

Implements score::gfx::ModelSceneDrawer.

setScene()

bool Gfx::GeometryViewer::SceneDrawer::setScene ( const ossia::scene_spec &  scene )

overridevirtual

The scene the renderer received; returns whether it is another one.

Implements score::gfx::ModelSceneDrawer.

update()

void Gfx::GeometryViewer::SceneDrawer::update ( score::gfx::RenderList &  renderer, QRhiResourceUpdateBatch &  res, score::gfx::PassMap &  passes, QRhiBuffer *  processUBO, QRhiBuffer *  cameraUBO, const SceneView &  view  )

overridevirtual

Once the passes of the renderer exist for the frame.

Implements score::gfx::ModelSceneDrawer.
