Man ir jautājums Smile Gribu OpenGLā fonā ielikt bildi (piemēram title skrīnam) - kā to izdarīt pareizi? (Protams var jau ielikt parastu plakni ekrāna priekšā, bet tas nu tā)

Ir kādas idejas?

Un kaada vaina lielam quadam ar textuuru? Tas laikam buutu viseertaakais un aatraakais variants. Ja ljoti gribaas kaut kaa savaadaak, vari pameegjinaat glDrawPixels - bet tur notiks kopeeshana no RAM uz framebufferi, kas buus diezgan leeni. Vai arii glCopyPixels - bet tur buus diezgan liela chakareeshanaas ar bufferiem... nu domaa pats Wink iesaku vienkaarshi quadu Wink

Skaidrs....tad palieku pie 'quada' (hmm...tad jau laikam spēlēs izmanto vienkārši plakni title-screen fonā (tas neattiecas uz 3D fona kā piemēram POPā). Ok, paldies! Very Happy
