◆ DrawGeometry() [1/5]

void Nanite::IRenderer::DrawGeometry ( FNaniteRasterPipelines &  RasterPipelines,
const FNaniteVisibilityQuery *  VisibilityQuery,
const FPackedViewArray &  ViewArray 
)
inline

Draw scene geometry by brute-force culling against all instances in the scene.

◆ DrawGeometry() [2/5]

void Nanite::IRenderer::DrawGeometry ( FNaniteRasterPipelines &  RasterPipelines,
const FNaniteVisibilityQuery *  VisibilityQuery,
const FPackedViewArray &  ViewArray,
const TConstArrayView< FInstanceDraw > &  InstanceDraws 
)
inline

Draw scene geometry driven by an explicit list FInstanceDraw (instance-id / view-id pairs).

◆ DrawGeometry() [3/5]

void Nanite::IRenderer::DrawGeometry ( FNaniteRasterPipelines &  RasterPipelines,
const FNaniteVisibilityQuery *  VisibilityQuery,
const FPackedViewArray &  ViewArray,
FSceneInstanceCullingQuery *  OptionalSceneInstanceCullingQuery 
)
inline

Draw scene geometry with and optional scene instance culling query. If non-null, the culling result is used to drive rendering, otherwise falls back to brute-force culling (as above).

◆ DrawGeometry() [4/5]

virtual void Nanite::IRenderer::DrawGeometry ( FNaniteRasterPipelines &  RasterPipelines,
const FNaniteVisibilityQuery *  VisibilityQuery,
const FPackedViewArray &  ViewArray,
FSceneInstanceCullingQuery *  OptionalSceneInstanceCullingQuery,
const TConstArrayView< FInstanceDraw > *  OptionalInstanceDraws 
)
pure virtual

Draw scene geometry with a CPU-provided view array

const FNaniteVisibilityQuery *  VisibilityQuery,
FRDGBufferRef  ViewsBuffer,
