on_attach()

void MayaFlux::Buffers::VolumeFieldProcessor::on_attach ( const std::shared_ptr< Buffer > &  buffer )

overrideprotectedvirtual

Cache and validate the volume, size the dispatch, write the shared parameter prefix, then call on_volume_ready.

Parameters

buffer

The attached buffer, expected to be a VolumeGridBuffer.

On any validation failure the cached volume is reset, which makes on_before_execute reject every subsequent cycle.

Reimplemented from MayaFlux::Buffers::ShaderProcessor.
