NVIDIA“钛[Ti]”系列显卡实测报告

Cho通知我说他们已经在国内率先测试了Nvidia GeForce Ti系列显卡：

"虽然GeForce3 Ti500和GeForce3使用同样的架构，也就是说两者是具备同样的功能的，但是NVIDIA在随Ti500/Ti200的资料中，特别提到了两个特性：NVIDIA 3D Texture[NVIDIA 3D纹理]和NVIDIA Shadow Buffer[NVIDIA 阴影缓冲]。

目前最普遍应用的纹理是类似256X256这样的2D纹理，而3D Texture[3D纹理]就是指具备三维坐标的纹理，描述方式是256X256X256的样子，较普通的2D纹理增加了一个“深度信息”。其实最早在游戏卡上实现3D Texture游戏卡上实现的最早是ATi的R100/Rage6C——RADEON，很遗憾的是，Radeon的3D Texture由于不支持mip-Mapping，实际的执行效果令人失望，没有什么实用意义...

...NVIDIA Shadow Buffer是GF3 Ti GPU使用创新的方式来生成光打在复杂对象后在场景中形成的平滑阴影效果，除了需要增加略干新的硬件单元以外，还需要传统的纹理贴图技术共同参与。"
