Direct3D9的學習曆程四:Direct3D9中的顔色混合

Alpha blending allows combining the pixels of the primitive currently being rasterized with the pixel values previously written at the same locations on the back buffer.

alpha混合(透明混合)允許幾何圖形的象素在後天緩存的同一位置上進行多個象素值的光栅化處理。

The blend factors allow us to control how the source and destination pixels are blended together.

混合因子允許我們控制，以何種方式來混合目标象素與源象素。

Alpha information can come from the diffuse component of  the primitive's material alpha channel of the primitive's texture.

alpha資訊可以從幾何紋理的幾何材質透明通道的擴充部分取得。
