資源簡介

要實(shí)現(xiàn)基于OpenGL ES 2.0的陰影映射，要攻克這三個(gè)技術(shù)難點(diǎn)： 1、 熟練操作FBO。幀緩存FBO是需要熟練操控的，因?yàn)镕BO可以很快地將深度圖寫入一塊顯存中，然后作為紋理渲染到真實(shí)的場(chǎng)景中。 2、 掌握著色器的使用。由于OpenGL ES 2.0只允許使用著色器來對(duì)其進(jìn)行渲染，因此對(duì)著色器的書寫熟練程度要求較高。 3、 掌握將float深度數(shù)據(jù)分拆成vec4再將vec4合并成float的操作。這個(gè)已經(jīng)成為業(yè)內(nèi)熟練掌握的技能之一了，網(wǎng)絡(luò)上搜索“how to pack float into RGBA”，能夠得到很多有用的回答。
