Hello, when I study the “Electric Dreams” (The PCG project), I find when we get attribute, the metadata is needed
I don’t know what is that mean. I think if I want to get value of point’s attribute, I only need point and attribute name. What is the metadata.
Besides, sometimes the example use outmetadata from loop body
Sometimes, the const metadata is used.
I really don’t know why and what difference between them.
Thanks!
