Kātaitai 3D Graphics
Ka tātuhia he mata z = f (x, y) i roto i te 3D whakawhitiwhiti — whakarerekē me te whakawhānui, wātea i runga anō.
Ka whakaruru te mata kia tahuri. Hei tauira x^2-y^2, sin(x)*cos(y), sqrt(x^2+y^2)
Mo tēnei tātaitai
the calculator plots a surface defined by z = f(x, y) as a rotatable wireframe, enter an expression in x and y, such as sin(x) * cos(y) or x^2 - y^2, and drag to orbit the surface in three dimensions. Useful for visualizing multivariable functions, saddle points and peaks. Dragging orbits the camera around the surface so you can look at it from any angle, and the zoom control moves you closer or further away. This turns an abstract two-variable formula into a shape you can actually see — hills, valleys, ridges and the pass-shaped saddle points where a surface rises in one direction while falling in another. This turns an abstract two-variable formula into a shape you can actually see.For example, z = x^2 - y^2 is used in multivariable calculus to plot a surface defined by z
Ko nga pātai e pā ana
He pēhea te tāuru i tētahi taumahi 3D?
Type i tētahi kīanga i roto i te x me te y, hei tauira, x^2 - y^2, kōaro rānei (x) * kōaro (y). Ka arotakea e te tātaitai i runga i tētahi kāwai, ā, ka tātuhia te mata hua.
Ka taea e au te huri i te mata?
He. Ka whakatere te mata kia puta ai, a, ka whakamahia te whakahaere pūwhiti ki te neke tata, ki te tawhiti rānei.
He aha te tikanga o te z = f (x, y)?
Ko te tikanga o tēnei ko te tiketike z o te mata i ia ira e mahia ana mai i ngā taururuku x me y o taua ira. Ka whiwhi te (x, y) i runga i te rererangi matatini i tētahi tiketike, ā, ko ēnei tiketike e whakakotahi ana hei hanga i te mata.
He pēhea te tātuhi i tētahi mata ārai?
Ka tāuru x^2 - y^2. Ka tae ki runga i tētahi tuaka, ā, ka tū i te taha o te atu, e tū ana i tētahi pito ārai i te taketake — te tauira paerewa o tētahi mata kāore he tiketike, he raorao rānei i reira.
He aha ngā momo mata ka taea e au te kite?
Ka taea e koe te tuhi i tētahi mea hei kīanga i roto i te x me te y: ngā paraboloids (x^2 + y^2), ngā kākahu (x^2 - y^2), ngā ripples (hina (x) * kōaro (y)) me ngā pahekotanga o ngā tārua, o ngā hiko, o ngā pūtake me ngā taupū.
He pēhea te rerekētanga o tēnei i te tātaitai tātai 2D?
Ko te utauta 2D e whakataki ana i te y = f(x) hei ānau i runga i tētahi kāwai matatini. Ko tēnei utauta 3D e whakataki ana i te z = f(x, y) hei mata i roto i te mokowā, kia whakaaturia ai te āhua o te uara i runga i ngā tāuru e rua i te wā kotahi, kaua ko tētahi.
Ko ngā hua he whakataunga mō te tohutohu ahuwhānui anake, ehara i te tohutohu moni, rongoā, tāke rānei.
