CLOUDVIEWER_TEMPLATE_VECTORIZED

#define CLOUDVIEWER_TEMPLATE_VECTORIZED	(		T,
			ISPCKernel,
			...
	)

CLOUDVIEWER_TEMPLATE_VECTORIZED(T, ISPCKernel, ...)

Defines a lambda function to call the provided template-like kernel. Supported types:

• bool
• unsigned + signed {8,16,32,64} bit integers,
• float, double

Use the CLOUDVIEWER_EXPORT_TEMPLATE_VECTORIZED macro to define the kernel in the ISPC source file.

Note: The arguments to the kernel only have to exist if ISPC support is enabled via BUILD_ISPC_MODULE=ON.

CLOUDVIEWER_VECTORIZED

#define CLOUDVIEWER_VECTORIZED	(		ISPCKernel,
			...
	)

Value:

    [&](int64_t start, int64_t end) {                                       \
        CLOUDVIEWER_CALL_ISPC_KERNEL_(ISPCKernel, start, end, __VA_ARGS__); \
    }

CLOUDVIEWER_VECTORIZED(ISPCKernel, ...)

Defines a lambda function to call the provided kernel.

Use the CLOUDVIEWER_EXPORT_TEMPLATE_VECTORIZED macro to define the kernel in the ISPC source file.

Note: The arguments to the kernel only have to exist if ISPC support is enabled via BUILD_ISPC_MODULE=ON.
