With the era of programmable graphics hardware, shader replaces the traditional fixed rendering pipeline to achieve more realistic effects.

随着可编程图形硬件时代的到来，着色器替代了传统的固定渲染管线以实现更加逼真的图像效果。

Finally, the shadow texture is mapped to a corresponding surface in 3D scene by projective texture based on programmable graphics hardware.

最后，在可编程图形硬件上，采取投影纹理映射技术将阴影纹理投射到场景中的相应表面。
