The image exhibits three-dimensional characteristics, i.e., the parallax effect . 物象显现三维特征,也即具有视差效应。
In other words, for the parallax effect to be visible, you need to be close the surface and look at it from a low angle 总之,为了看出视差贴图的效果,你必须靠近平面并且以低的视角去看。
The view angle must be low : if you're on the top of the surface, looking down, even when you're close : no parallax effect 视角要低角度,如果你垂直观看对象,甚至你的鼻尖已经碰到它了,视差贴图仍然会失效。
The view angle must be low : if you're on the top of the surface, looking down, even when you're close : no parallax effect 视角必须够低:如果你从平面的正上方往下看,就算你凑得再近,都看不出视差贴图的效果。
Terrain texture : the camera is at a low distance with a low angle . the parallax effect can clearly be visible-this is the good case for the algorithm !- 地表材质:镜头位于较低的高度并且视角也很低。视差贴图的效果可以很明显地看出来?这是个演示该技术的好案例。
Terrain texture : the camera is at a low distance with a low angle . the parallax effect can clearly be visible-this is the good case for the algorithm !- 地型纹理:现在以一个低距离,低角度的视角来观看这一个行星表面。我们可以明显的发现,在使用视差映像技术后,图片更清晰更有立体感!
