bind_typed_push_constant()

void MayaFlux::Buffers::FormaBindingsProcessor::bind_typed_push_constant	(	const std::string &	name,
		std::function< Kakshya::GpuValue()>	reader,
		uint32_t	offset
	)

Bind a typed reader to a push constant slot.

The value is written as its own format's bytes at the offset, with no conversion, so vectors and matrices keep every component. The slot is as wide as the value each tick.

Parameters

name	Logical binding name.
reader	Callable returning the current value each tick.
offset	Byte offset in the push constant struct.
