Detailed Description

template<typename RenderableCompare>
class Carna::base::GeometryStage< RenderableCompare >

Partially implements a rendering stage that uses at least one render queue for rendering geometry from the scene graph.

Parameters
RenderableCompareDefines partial order of renderables that is applied to the predefined rendering queue of this stage. Set this to void if no particular order is required.

Override updateRenderQueues and rewindRenderQueues if you require further rendering queues.

Member Function Documentation

◆ prepareFrame()

template<typename RenderableCompare >
void Carna::base::GeometryStage< RenderableCompare >::prepareFrame ( Node root)
overridevirtual

Called once before each frame.

Reimplemented from Carna::base::RenderStage.

Definition at line 189 of file GeometryStage.h.

◆ renderPass()

template<typename RenderableCompare >
void Carna::base::GeometryStage< RenderableCompare >::renderPass ( const math::Matrix4f viewTransform,
RenderTask rt,
const Viewport vp 
)
overridevirtual

Called once per pass.

If this rendering stage maintains one or more Carna::base::RenderQueue objects, than this is the right place to build them. Note that the queues need to be rebuilt only once per frame and not per pass, unless isViewTransformFixed is false. If it is true and this is not the first invocation of this method since the last time prepareFrame was called, rewinding the queue will be sufficient.

Implements Carna::base::RenderStage.

Reimplemented in Carna::presets::VolumeRenderingStage, Carna::presets::DVRStage, Carna::presets::DRRStage, Carna::presets::MeshColorCodingStage, Carna::base::MeshRenderingStage< RenderableCompare >, Carna::base::MeshRenderingStage< base::Renderable::BackToFront >, Carna::presets::MaskRenderingStage, Carna::presets::MIPStage, Carna::presets::CuttingPlanesStage, and Carna::presets::TransparentRenderingStage.

Definition at line 226 of file GeometryStage.h.

◆ videoResource()

template<typename RenderableCompare >
template<typename GeometryFeatureType >
const GeometryFeatureType::ManagedInterface & Carna::base::GeometryStage< RenderableCompare >::videoResource ( const GeometryFeatureType &  geometryFeature) const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
