如何生成更逼真的衣物图像
FILMS like Captain America , Tron Legacy and The Curious Case of Benjamin Button haveshown that it is possible to use computer-generated imagery to make actors lookyounger, older or wimpier than they actually are, in a surprisingly realistic manner.
电影《美国上尉》、《创战记》和《本杰明?巴顿奇事》表明计算机图像生成技术能以惊人的逼真手法使演员看上去比实际更年轻、老态或懦弱。
At least, it is possible if those altered actors are kept at a suitable distance from theviewer.
这种效果至少在那些被改造过的演员与观众保持合适距离时能够实现。
The difficulty of recreating the textures of both skin and fabric means the effect is lessconvincing when seen close up.
皮肤和面料纹理重建的困难在于它们被放大观看时,效果并不理想。
The reason is that, whereas it is possible to simulate realistically the forces which makevirtual skin and fabric hang, bend, flap and stretch, recreating the subtle ways theyreflect light has so far proved extremely tricky.
原因在于尽管计算机能够真实地模拟使虚拟皮肤及面料产生悬挂、弯曲、飘动和拉伸的外力,但迄今为止想要找到构建反射光的精妙方法仍是极为困难的事情。
