What is Signed Distance Functions?
Ọrụ dị anya bịanyere aka na ya (SDF) na-akọwa ọdịdị 3D site n'ịgwa gị, maka ebe ọ bụla dị na mbara igwe, ka ọ dị n'ebe dị nso, yana akara na-egosi ma ị nọ n'ime ma ọ bụ n'èzí. Kọmpat a, ihe nnochite anya na-aga n'ihu na-enye ike nrụgharị 3D ọgbara ọhụrụ, nrụpụta, na ọdịdị ọdịdị.
Kedu ihe ọrụ anya bịanyere aka na ya ga-alaghachi maka isi ihe 3D enyere?
Otu SDF na-esetịpụ isi ihe ọ bụla na anya ya site na elu kacha nso; akara na-egosi ma isi ihe dị n'ime (adịghị mma) ma ọ bụ n'èzí (nke ọma).
Ebee ka elu SDF dị n'ezie?
N'elu bụ ntọala nke ebe ebe aka aka bịanyere aka na ya bụ efu efu, oke n'etiti ime na n'èzí.
Kedu ihe onwunwe ezi gradient SDF na-emeju afọ?
SDF dị irè na-erube isi na nhatanha eikonal, yabụ gradient ya nwere ogologo nkeji ebe niile wee tụọ aka n'elu nkịtị.
