Kawa diitihi sudut pandangnya bagarak matan sabuting sisi ka sabuting sisi lainnya, ubjik nang tajauh kalihatan bagarak talambat pada ubjik nang taparak lawan kamera. Di kasus ngini, kutak putih nang ada di muka kalihatan bagarak tacapat pada kutak warna hijau nang ada ditangah.

Paralaks (baasal matan kata Yunani Bahari παράλλαξις (parallaxis) nang artinya alternisasi) marupakan pamindahan atawa parbidaan dalam malihat andak sabuting ubjik lawan dua buting sudut pandang nang balain wan diukur lawan sudut atawa semi-sudut kamiringan antara dua garis ngitu. Maraga perspektif, ubjik nang taparak manampaiakan paralaks nang taganal pada ubjik nang tajauh amun diitihi matan andak nang balaian, jadi paralaks kawa dipakai gasan manantuakan jarak.

Sudut pandang sanjata
Paralaks bapangaruh lawan alat panglihatan matan sanjata jarak jauh dalam banyak hal. Kekeran nang dipasang di sanjata halus wan busur, wan sanjata lainnya., jarak tegak lurus antara panglihatan wan sumbu paluncuran sanjata (misalnya kaliber paluncuran matan sanjata) biasanya dipinandui lawan ngaran "katinggian panglihatan" kawa maalami kasalahan mangeker nang liwar banar pas manimbak di jarak nang parak, apalagi pas manimbak target nang halus.  Kasalahan paralaks ngini disaimbangakan (pas diparluakan) mamakai pahitungan nang mamarluakan jua variabel nang lain kaya gugurnya paluru, katahanan angin lawan ubjik, wan jarak target nang diparkiraakan.
