Ukugenca «I-GLMatrix»

Okwami okuthunyelwe kwesibili.. .. Ngizokukhombisa (into abanye abangayithola ingenamsebenzi) njenge shintsha umbala kwe-screensaver engisithandayo (i-screensaver, i-screensaver) mayelana xscreensaver, I-GLMatrix, okuthi uma ungazi ukuthi yisimulator yezimpawu ezijwayelekile eziwela esiqeshini ngesitayela seMatrix ngemiphumela emihle ye-3D. Nasi isithombe:

Njengoba ngicasula impela, futhi ikhompyutha yami yenziwe ngezifiso ngemibala emnyama nohlobo oluhlaza okwesibhakabhaka I-Arch Linux (ebukeka kahle ngekhibhodi yami eluhlaza okwesibhakabhaka xD) .. ..okujwayelekile umbala oluhlaza ye-Matrix, ayingihlanganisi (noma njengoba umuntu angasho lapha naphakathi kwezingane, ayishayi ngisho ne-mucus).

Ukufeza lokhu, sizokwenza ukungenela kwikhodi yomthombo ye-xscreensaver, ungatatazeli abangenalwazi, kulula, futhi ngizokwenza kanjalo khombisa igxathu negxathu ukuze bakufinyelele; ngalokhu ngifuna ukukutshela, ukuthi angizukushiya izinto esezihlafunwe, kodwa lokho umqondo ngukuthi bathathe isiphuzo bese bebeka isandla..ngasabi.

Asikwenze..

1- Landa ikhodi yomthombo ye-xscreensaver.

Singafaka ikhasi le-xscreensaver, futhi siyalanda inguqulo yakamuva ye ikhodi yomthombo (ikhodi yomthombo).

Noma singakwazi landa ngqo kusukela Isikhumulo con wget, ukwazi njalo i- inguqulo yayo, esimweni esinjalo 5.20:

 $ wget http://www.jwz.org/xscreensaver/xscreensaver-5.20.tar.gz

Siyayivula ku-zip:

 $ tar -xf xscreensaver-5.20.tar.gz

 2- Bheka ukuncika kwakho.

Sizoqinisekisa ukuthi sine- amaphakheji adingekayo ukuze i-xscreensaver isetshenziswe, kulokhu sizosebenzisa 'ukulungisa'. Kumele naka ekuphumeni (Okukhiphayo) abasinika zona, ukwazi ukuthi thina enye iphakheji ayikho, noma kukhona iphutha. Uma ngabe iphasela lilahlekile, lifune bese ulilanda (kungaba ngama-synaptics, apt, pacman, njll - kuya ngokuthanda kanye ne-distros).

-Sifaka ifolda entsha engafakwanga uziphu:

 $ cd xscreensaver-5.20/

Senza okulandelayo:

 $ ./configure

3- Siqinisekisa ukusebenza okulungile.

Uma kungekho phakheji elahlekile, futhi awunayo alikho iphutha; siqhubeka faka i-xscreensaver, ukuqinisekisa ukuthi isebenza kahle.

Sikhipha:

 $ make

Uma kungekho maphutha ekwakhiweni, njengomsebenzisi 'impande' siyifaka:

 # make install

Sihlola:

 $ xscreensaver-demo

4- Shintsha /hacks/glx/glmatrix.c

Bazokhuluma nababo umhleli wombhalo intandokazi (i-vim, i-nano, i-gedit, njll) kimi ngabona, ifayili esizoliguqula kuleli cala:

 $ vi ./hacks/glx/glmatrix.c

Kufanele bathole ifayela le- vimba nalokhu okulandelayo indlela:
{
unsigned long p = XGetPixel (xi, x, y);
unsigned char r = (p >> rpos) & 0xFF;
unsigned char g = (p >> gpos) & 0xFF;
unsigned char b = (p >> bpos) & 0xFF;
unsigned char a = g;
g = 0xFF;
p = (r << rpos) | (g << gpos) | (b << bpos) | (a << apos);
XPutPixel (xi, x, y, p);
}

Y siyengeza ngokulandelayo umbala oyifunayo:
{
unsigned long p = XGetPixel (xi, x, y);
unsigned char r = (p >> rpos) & 0xFF;
unsigned char g = (p >> gpos) & 0xFF;
unsigned char b = (p >> bpos) & 0xFF;
unsigned char a = g;
r = 0x71;
g = 0x93;
b = 0xD1;
p = (r << rpos) | (g << gpos) | (b << bpos) | (a << apos);
XPutPixel (xi, x, y, p);
}
Ukuba phakathi I-RGB Hexadecimal (obomvu-luhlaza-luhlaza okwesibhakabhaka)

Isibonelo, okuluhlaza okwesibhakabhaka kwesici I-Arch Linux ingabe: #1793D1, okusele:

r=0x71;
g=0x93;
b = 0xD1;

Siyaqhubeka izinguquko.

5- Sihlanganisa kabusha i-xscreensaver entsha ne-glmatrix eguquliwe.

Kuleli qophelo sizokwenza cishe ngendlela efanayo nase- iphuzu 2, kepha kulokhu ukuthatha izinguquko esizenzile.

Sikhipha:

 $ make clean

Bese:

 $ make

Uma ngabe alukho uhlobo lwephutha olwazile ukwenziwa, njengomsebenzisi 'impande' senza:

 # make install

6- Sisebenzisa, siqinisekisa, silungiselela futhi siyakujabulela.

Sikhipha:

 $ xscreensaver-demo

Ohlwini esikukhethayo I-GLMatrix:

Futhi ekwethulweni kufanele ngabe sekuvele kubonakala ngombala abawukhethile.

Lungiselela ukunambitha .. futhi ukujabulela (I.

7- Ezinye izibonelo zemibala ehlukene. (+ ICEBISO)

ISU: ukwazi a umbala en I-Hexadecimal ngisebenzisa I-GIMP, sivula iphalethi yombala bese sibala njenge "Ukubhalwa kwe-HTML". Singacindezela futhi 'o'bese uthatha umbala wesithombe ukwazi ukuthi umbala waso unjani kuHex.

Ngiyethemba ukujabulele ukuzama nokukubhala njengami. Unganqikazi ukubuza nganoma yimiphi imibuzo.

Ukugenca okuhle ..
