The image exhibits three-dimensional characteristics, i.e., the parallax effect . 物象顯現三維特征,也即具有視差效應。
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 總之,為了看出視差貼圖的效果,你必須靠近平面并且以低的視角去看。
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 視角要低角度,如果你垂直觀看對象,甚至你的鼻尖已經碰到它了,視差貼圖仍然會失效。
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 視角必須夠低:如果你從平面的正上方往下看,就算你湊得再近,都看不出視差貼圖的效果。
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 ! - 地表材質:鏡頭位于較低的高度并且視角也很低。視差貼圖的效果可以很明顯地看出來?這是個演示該技術的好案例。
