class PaperDrawCallFactory

Defined at line 24 of file ../../src/ui/lib/escher/paper/paper_draw_call_factory.h

PaperDrawCallFactory generates PaperDrawCalls and enqueues them into a

PaperRenderQueue. The number of draw-calls and the precise details of each

depend on the factory's configuration (e.g. the current shadow algorithm),

which is controlled by PaperRenderer that owns the factory.

void PaperDrawCallFactory (const PaperDrawCallFactory & )

void set_track_cache_entries (bool track)

TODO(ES203) - We will eventualy not need to do this as we will simply

inject PaperRenderer with a version of the PaperDrawCallFactory that

is used explicitly for testing.

When this is set to true, no draw calls get enqueued and instead,

PaperDrawCallFactory will accumulate a list of cache entries that

would have been drawn.

void PaperDrawCallFactory (EscherWeakPtr weak_escher, const PaperRendererConfig & config)

|weak_escher| is used only to create |white_texture_|; it is not retained.

void DrawCircle (float radius, const PaperMaterial & material, PaperDrawableFlags flags)

Draw the specified shape by obtaining a mesh from |PaperShapeCache| and

generating/enqueuing draw calls via |EnqueueDrawCalls()|.

void DrawMesh (const MeshPtr & mesh, const PaperMaterial & material, PaperDrawableFlags flags)

We are currently unable to clip meshes that are already provided to us and not generated

from the PaperShapeCache, and so we render them directly without doing any clipping. It is

possible to clip on the GPU, but this functionality is not available on all hardware, and

performing clipping on the GPU means our existing stencil shadow implementation will no

longer work.

void SetConfig (const PaperRendererConfig & config)

Must not be called during a frame, i.e. between |BeginFrame()| and |EndFrame()|.
