/// The interface class representing user-programmable rendering kernel components.
///
/// There are two sub-classes from this interface representing rendering kernel programs applied to volumetric
/// primitives, such as regular volumes (\c IVolume_sample_program), and applied to surface primitives, such as
/// regular heightfields or planes (\c ISurface_sample_program). These classes act as scene attributes to the
/// particular scene elements.
///
/// These programs are not compiled in-place but on each rendering node depending on the encountered GPU-devices and
/// their particular compute capabilities. Failure to compile a rendering kernel program results in an error
/// containing the compile log. In order to indicate such a failure to the user, the primitives the particular program
/// attribute is applied to are rendered in a signal color (deep-pink color).
///
/// \note For best performance of the compiled rendering kernels, methods defined in device code need to be
/// decorated with special qualifiers. The qualifiers required by NVIDIA IndeX are covered by the
/// \c NV_IDX_DEVICE_INLINE_MEMBER macro. While it is not strictly required to use this macro, it is advised to do so.

/// The interface class representing user-defined parameter buffers for user-programmable rendering kernel components.

/// User-defined parameter buffers allow the application to define custom input to \c IRendering_kernel_program
/// instances. Such input can be utilized to implement custom rendering kernel programs independent of the input made
/// available through the NVIDIA IndeX rendering kernel interfaces. For instance, an application is enabled to
/// implement a specialized material shading method that is not pre-defined by any existing NVIDIA IndeX rendering
/// properties. The required material parameters, unknown to the actual rendering system, are passed through this
/// interface class to NVIDIA IndeX, which handles the distribution of such data to each rendering node and rendering
/// device. The interface class acts as a scene attribute to scene elements enabled to utilize rendering kernel components
/// (\c IRendering_kernel_program).
///
/// Each instance of this interface allows for a certain number of data buffers to be added. The buffer data is
/// assigned to so called buffer slots. These buffer slots are a way to identify the actual buffers and access them
/// in the rendering kernel programs, as shown in the following example code snippet of a volume sample program.
///
/// This example illustrates the input of clip-plane parameters on the application side:
///
/// \code
/// struct Plane_data_struct
/// {
///     mi::math::Vector<mi::Float32, 4>   plane_equation;
/// };
///
/// // Define two clip planes
/// Plane_data_struct planes[2];
///
/// // First clip plane
/// mi::math::Vector<mi::Float32, 3> clip_plane_0_normal = mi::math::Vector<mi::Float32, 3>(1.0f, 1.0f, -1.0f);
/// clip_plane_0_normal.normalize();
/// planes[0].plane_equation = mi::math::Vector<mi::Float32, 4>(clip_plane_0_normal, -11.0f);
///
/// // Second clip plane
/// mi::math::Vector<mi::Float32, 3> clip_plane_1_normal = mi::math::Vector<mi::Float32, 3>(-1.0f, 1.0f, 1.0f);
/// clip_plane_1_normal.normalize();
/// planes[1].plane_equation = mi::math::Vector<mi::Float32, 4>(clip_plane_1_normal, 10.0f);
///
/// // Add the two defined planes to the rendering kernel parameter buffers
/// kernel_param_buffers->set_buffer_data(CLIP_PLANE_PARAM_BUFFER_SLOT, planes, sizeof(Plane_data_struct) * 2);

///         m_plane_buffer_1 = state.bind_parameter_buffer<Plane_data_buffer>(0, 1 /*array offset*/);
///     }
/// ...
///     NV_IDX_DEVICE_INLINE_MEMBER
///     int execute(
///        const Sample_info_self&     sample_info,
///              Sample_output&        sample_output)

///         const float dist_p_00 = dot(m_plane_array_buffer[0].plane_equation, make_float4(sample_info.sample_position, 1.0f));
///         const float dist_p_01 = dot(m_plane_array_buffer[1].plane_equation, make_float4(sample_info.sample_position, 1.0f));
/// \endcode
///
/// or to access the same data through the separate entries:
///
/// \code
///         const float dist_p_00 = dot(m_plane_buffer_0->plane_equation, make_float4(sample_info.sample_position, 1.0f));
///         const float dist_p_01 = dot(m_plane_buffer_1->plane_equation, make_float4(sample_info.sample_position, 1.0f));
/// ...
/// };
/// \endcode
///
/// As shown in the above example the association of data input through this interface class and the actual data
/// at runtime happens through the buffer slot identifiers. Further, the example illustrates that a buffer slot can
/// actually hold an array of structures (in this example an array of \c Plane_data_buffer instances). It is possible
/// to access such arrays in a straightforward way through the array index operator or by binding the contents of the
/// array to individual variables. The function to perform the binding (\c state.bind_parameter_buffer()) allows both use
/// cases:
///
/// \code
/// NV_IDX_DEVICE_INLINE_MEMBER
/// const T* bind_parameter_buffer(
///             unsigned buffer_slot,
///             unsigned buffer_slot_offset = 0u);
/// \endcode
///
/// The \c buffer_slot_offset parameter allows to select a particular array element. The offset unit is the actual
/// number of array elements to offset the binding.
///
/// It is important to note that the contents of the buffer data input through this interface must conform to certain
/// rules to ensure data consistency between the host and device data. Especially, data alignment of buffer contents
/// must be regarded. For example, certain vector data types require alignment to special boundaries inside structures:
/// http://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#vector-types__alignment-requirements-in-device-code
///
/// Example for misaligned data between host and device:
///
/// \code
/// struct wrong_alignment
/// {
///     float3  normal;
///     float4  color; // misaligned
/// };
/// \endcode
///
/// In this example the 'color' entry of the structure is not correctly aligned to the struct. A \c float4 variable requires
/// a 4 byte alignment. Such cases can be corrected by manually adding padding data:
///
/// \code
/// struct correct_alignment
/// {
///     float3  normal;
///     char    padding_data[4]; // align the next entry to a 4 byte boundary
///     float4  color;
/// };
/// \endcode
///
/// Similarly, when storing multiple elements in an array of structures, the individual structures require alignment to
/// a certain boundary. This required array offset alignment can be queried through this interface using the
/// \c get_array_offset_alignment() method. In order to achieve correct structure alignment, padding data can be used:
///
/// \code
/// struct array_element
/// {
///     float material_property_0;
///     float material_property_1;
///     float material_property_2;
///     char  padding[4]; // pad structure to multiple of 16 bytes
/// };

/// Each volume sample program is also required to have the \c NV_IDX_VOLUME_SAMPLE_PROGRAM macro as the first

/// The \c initialize() method can be used to initialize variables used in the per-sample computation of the

///
/// The \c execute() method always receives the current sample position as input and the output color as output. Through

/// Each instance of a volume sample program has access to a state variable allowing access to the current volume data
/// set as well as the current colormap. The contents of this state is derived from the scene definition. The state
/// is accessed through the \c state variable available to each instance. The state contains a \c volume and \c colormap
/// variable, which can be used to sample the volume and lookup color and opacity values from a colormap, as demonstrated
/// in the example above. It is important to note that the return value of the \c sample() method is dependent on the
/// actual volume type. A scalar volume, such as \c uint8 or \c float32 volumes return a simple float value, whereas RGBA-
/// volumes return a \c float4 value.
