Detailed Description

This interface can be used to obtain the MDL backends.

Member Enumeration Documentation

Currently available MDL backends.

Enumerator
MB_CUDA_PTX	Generate CUDA PTX code.
MB_LLVM_IR	Generate LLVM IR (LLVM 12.0 compatible).
MB_GLSL	Generate GLSL code.
MB_NATIVE	Generate native code.
MB_HLSL	Generate HLSL code.

virtual IMdl_backend * mi::neuraylib::IMdl_backend_api::get_backend ( Mdl_backend_kind kind )

pure virtual

Returns an MDL backend generator.

Parameters

kind	The desired backend generator.

Returns: The backend generator, or nullptr if the requested backend is not available.

virtual const Float32 * mi::neuraylib::IMdl_backend_api::get_df_data_texture	(	Df_data_kind	kind,
		Size &	rx,
		Size &	ry,
		Size &	rz,
		const char *&	pixel_type
	)		const

pure virtual

Returns the distribution function data of the texture identified by kind.

Parameters

	kind	The kind of the distribution function data texture.
[out]	rx	The resolution of the texture in x.
[out]	ry	The resolution of the texture in y.
[out]	rz	The resolution of the texture in z.
[out]	pixel_type	The type of the data elements.

Returns: A pointer to the texture data or nullptr, if kind does not correspond to a distribution function data texture.
