Akọwa jiometrị - na nke ahụ bụ frontal ụgbọelu?

Iji nweta ihe echiche banyere isiokwu mee ya image na akwụkwọ ma ọ bụ ihuenyo. A, isiokwu image na onye ọ bụla n'ime ndị ọzọ adịghị enye a zuru foto nke ya ụdị, ọ na-achọrọ na-enweta ya ntule na abụọ ma ọ bụ atọ ụgbọ elu. Streamline na usoro nke ntule, ụgbọelu nke ntule-ewe ebe, perpendicularly ọ bụla ọzọ. Tụlee, ihe ndị ahụ dị iche iche ụgbọ elu. All atọ nke ha, ha na-etolite a zita ohere a nri n'akuku.

Onye ọ bụla nke ntule ụgbọ elu nwere ya aha na lettering. Frontal ụgbọelu - a ekwesị enịm tupu anyị anya ntule ụgbọelu. N'ihi na ihe doo anya - na ọ bụ a ụgbọelu, nke anyị na-na-eche ihu, ya bụ, anyị na-enyocha ụgbọelu nke picture ... Ẹkedọhọde n'ihu ụgbọelu nke Latin akwụkwọ ozi V.

Kwụ ụgbọelu bụ perpendicular ka n'ihu. N'ụzọ ihe atụ na-ekwu okwu, ndị kwụ ụgbọelu - nke a bụ ụgbọelu nke na-na-na anyị "n'okpuru ụkwụ ya." Ọ na-emekarị denoted site n'akwụkwọ ozi H.

The atọ nke isi ntule ụgbọ elu a na-akpọ a profaịlụ. Dị ka frontal ụgbọelu, ọ na-emi odude ekwesị na Nleta a nri n'akuku na aga abụọ. Rụtụ aka na profaịlụ ụgbọelu Latin akwụkwọ ozi W.

Mgbe pairwise nrutu nke atọ ụgbọ elu nke data eme ahazi axis x, y, z. Nke a apụta perpendicular ụzarị na a nkịtị vertex na nrutu nke atọ ụgbọ elu nke ntule, denoted site n'akwụkwọ ozi O.

Iji nweta ihe ọmụma zuru ezu onyinyo nke ihe, ọ na-achọrọ ikpokọta oyiyi nwetara na atọ ibe perpendicular ihu. Iji mezuo nke a, abụọ ihu nke n'akuku idokwa na ikpokọta na nke atọ. Frontal ụgbọelu na-anọgide na ebe, kwụ-agba gburugburu n'ala site 90 Celsius tinyere x-axis, a profaịlụ ụgbọelu na-agba gburugburu nri site 90 Celsius tinyere z axis. N'ihi ya abụọ ikpeazụ ụgbọelu kwekọọ n'ihu (dị n'okpuru ndị kwụ, profaịlụ - aka nri).

The akọwa jiometrị ọ bụla ọ na-amanye emi odude ke eru ụgbọelu nwere ike kọwaa na ụzọ dị iche iche: atọ projections adịghị ịgha ụgha na a ogologo akara nke ihe, a ogologo akara ntule na a mgbe n'èzí ya, nakwa dị ka projections ukem ma ọ bụ intersecting edoghi ma ọ bụ a ụgbọelu ọgụgụ.

Ikwu na isi ụgbọelu nke ntule ele ụgbọelu nwere ike na-na-esonụ ndokwa:

1. O nwere ike ịbụ na-abụghị perpendicular ọ bụla nke ha. Mgbe ahụ, ọ -. Ya mere na-akpọ. ọnyà ụgbọelu.

2. O nwere ike ịbụ otu n'ime atọ perpendicular ụgbọ elu nke ntule. N'ọnọdụ dị otú ahụ a na-akpọ a ịgbasapụ projecting, profiled ma ọ bụ-projecting frontally-projecting, karị, nke ụgbọelu nke bụ perpendicular ya.

3. The ụgbọelu nwere ike perpendicular ka ha abua na nke-atọ yiri. Mgbe ahụ, ọ na-akpọ n'ihu, kwụ ma ọ bụ profaịlụ karị.

Direct nwere ike ogide na-esonụ ọnọdụ ke mmekọrita ụgbọelu:

1. nke ya.

2. Bụrụ ya ẹbiet.

3. intersects ụgbọelu (a pụrụ iche ikpe - ka perpendicular)

Na ụgbọelu e nwere isi edoghi, na-akpọ ngwe na Frontale. Ọ edoghi dina n'ihe a ụgbọelu na yiri ka nwoke ụgbọ elu nke projections.

Ọ bụla ụgbọelu nwere ike na-anọchi anya dị ka r. N. ụgbọelu Chọpụta, ya bụ, e tinyere nke ọ intersects na ntule ụgbọelu. Metụtara nke ụgbọelu na-akpọ kwụ, frontal na profaịlụ. The isi nke nrutu na ụgbọelu nke anyụike nke projections na anyụike na-enwe a uche nke inyerịta nrutu nke ụgbọelu nke metụtara, ndị metụtara na-adịkarị na-akpọ edere ihe na ụgbọelu.

Kwụ na frontal ụgbọelu metụtara na ụgbọ elu nke projections idako na ha projections nke otu aha. Ọ kwesịkwara kwuru na niile kwụ otu ụgbọelu na-apụta ihe yiri na yiri kehoraizin track, nakwa dị ka ọ bụla nke ya frontal ibe yiri na yiri ya n'ihu ọgwụgwụ nzọ ụkwụ.
