◆ DISPATCH_DTYPE_TO_TEMPLATE

#define DISPATCH_DTYPE_TO_TEMPLATE	(	DTYPE,
		...
	)

Call a numerical templated function based on Dtype. Warp the function to a lambda function to use DISPATCH_DTYPE_TO_TEMPLATE.

Before: if (dtype == core::Float32) { func<float>(args); } else if (dtype == core::Float64) { func<double>(args); } else ...

Now: DISPATCH_DTYPE_TO_TEMPLATE(dtype, [&]() { func<scalar_t>(args); });

◆ DISPATCH_DTYPE_TO_TEMPLATE_WITH_BOOL

#define DISPATCH_DTYPE_TO_TEMPLATE_WITH_BOOL	(	DTYPE,

Value:

[&] {                                                   \
        if (DTYPE == open3d::core::Bool) {                  \
            using scalar_t = bool;                          \
            return __VA_ARGS__();                           \

            DISPATCH_DTYPE_TO_TEMPLATE(DTYPE, __VA_ARGS__); \
        }                                                   \
