bindings_from_spec()

std::vector< GpuBufferBinding > MayaFlux::Yantra::bindings_from_spec ( const Portal::Graphics::ShaderSpec &  spec )

inline

Derive a GpuBufferBinding list from a ShaderSpec.

Translates ShaderSpec binding declarations to the GpuBufferBinding vocabulary understood by GpuResourceManager and any GpuExecutionContext subclass. The result is suitable for passing to declare_buffer_bindings() overrides or directly to GpuResourceManager::initialise().
