DirectX 8 wypros

problema mi e sledniq kogato se zaredi edna tekstura tq se zarevda w interface i sled towa we4e nqmam dotyp do neq interesuwame kak da q promenq sled towa i po to4no ima li na4in da q wzema kato bitowa karta ili ne6to ot sorta t.e. da moga da q promenqma swobodno

wizh LockRect, UnlockRect i UpdateTexture - obache ima znachenie kak si alokiral texturata - kude i dali e manageble. Sushto trjabwa da imash predvid che ako imash mipmapi - trjabwa sam da si gi opravish (ako si gi vkljuchil de).

Leko sam propusnal njakoi raboti..

ako teksturite ti sa create-nati kato D3DPOOL_MANAGED mozhesh da lock-wash rectowe s LockRect() - toi ti wryshta directno ukazatel kym pametta (tuj razbira se e system memory kopieto na teksturata, ne e wyw video mem-a). Wnimawai da ne lockwash po-golqm rect otkolkoto ti trqbwa (primerno cqlata tekstura :) shot posle dx-a go kopira celiq rect ot system wyw video memory-to
teksturi koito si create-nal kato D3DPOOL_DEFAULT (demek wyw video/agp mem) mozhesh da promenqsh samo prez UpdateTexture(), za takiwa teksturi shte trqbwa da si dyrzhish D3DPOOL_SYSTEMMEM kopie za da lockwash i promenqsh nego, a sled tuj s UpdateTexture() da prashtash promenite wyrhu videoto...obache ne znam kolko ima smisyl da praish tyj, mozhe da probwash i taka no mi se chini che texturi deto mnogo she gi promenqsh nai-dobre da si gi prawish kato D3DPOOL_MANAGED...w kraq na kraishtata bi trqbwalo da se izwyrshwa syshtata operaciq samo che wytreshno...

mi na wqrno mqza....
obache s ei tuj
pLockedRect = new(D3DLOCKED_RECT);
naprawo me tryshna w zemqta

D3DLOCKED_RECT locked_rect;
...->LockRect( 0, &locked_rect, 0, 0 );

ei taka izglezhda po-chitawo :)

Аве гледам ги разбираш, я кажи това DirektX откъде мога да си го купя,а? На женския пазар нямаше, днес гледах...

abe Zemedelecyt gi razdawa, powechko mu ostanali ot minalogodishnata rekolta...trebe ot nego edno sa si poiskash :P

ami razdawa - dvoino po-skupo gi prodava ot normalnoto - wuobshte ne hodi ot nego da kupuwash - po dobre wish Skotowydetza
