clip((_Diffuse_Texture_var.a/0.5)–0.5)
Wherein, _ Diffuse_Texture_var.a variable represents the information parameter of Alpha passage, by the information parameter of Alpha passage divided by 0.5, and deduct the 0.5 (intermediate value of the 0.5 expression Alpha passage deducted, such as 128), if the result obtained is less than 0, then the position of correspondence is set to transparent region, if the result obtained is greater than 0, then the position of correspondence is set to opaque field.
AlphaBlend function is as follows:
fixed4finalRGBA＝fixed4(finalColor,(_Diffuse_Texture_var.a/0.5))
Wherein, _ Diffuse_Texture_var.a variable represents the information parameter of Alpha passage, by the information parameter of Alpha passage divided by 0.5, and deduct the 0.5 (intermediate value of the 0.5 expression Alpha passage deducted, such as 128), finally the result obtained is appointed as the transparency of corresponding position.
Again such as, shown in figure 5B, also the information parameter of Alpha passage can be multiplied by 2 to reduce its transparence information parameter originally represented.

Wherein, _ Diffuse_Texture_var.a variable represents the information parameter of Alpha passage, the information parameter of Alpha passage is multiplied by 2, and deduct the 0.5 (intermediate value of the 0.5 expression Alpha passage deducted, such as 128), if the result obtained is less than 0, then the position of correspondence is set to transparent region, if the result obtained is greater than 0, then the position of correspondence is set to opaque field.
AlphaBlend function is as follows:
fixed4finalRGBA＝fixed4(finalColor,(_Diffuse_Texture_var.a*2))
Wherein, _ Diffuse_Texture_var.a variable represents the information parameter of Alpha passage, the information parameter of Alpha passage is multiplied by 2, and deduct the 0.5 (intermediate value of the 0.5 expression Alpha passage deducted, such as 128), finally the result obtained is appointed as the transparency of corresponding position.
Again such as, shown in figure 5C, above-mentioned determining step can be carried out in AlphaClip function and AlphaBlend function, and when judging that the information parameter of Alpha passage is positioned at first passage interval, the information parameter of Alpha passage is multiplied by 2 to reduce its transparence information parameter originally represented.
AlphaClip function is as follows:
clip((min(_Diffuse_Texture_var.a,0.5)*2.0)-0.5)
Wherein, _ Diffuse_Texture_var.a variable represents the information parameter of Alpha passage, obtain information parameter and the 0.5 (intermediate value of 0.5 expression Alpha passage herein of Alpha passage, such as, 128) less value, less value is multiplied by 2, and deduct the 0.5 (intermediate value of the 0.5 expression Alpha passage deducted, such as 128), if the result obtained is less than 0, then the position of correspondence is set to transparent region, if the result obtained is greater than 0, then the position of correspondence is set to opaque field.
AlphaBlend function is as follows:
fixed4finalRGBA＝fixed4(finalColor,(min(_Diffuse_Texture_var.a,0.5)*2.0))
Wherein, _ Diffuse_Texture_var.a variable represents the information parameter of Alpha passage, obtain information parameter and the 0.5 (intermediate value of 0.5 expression Alpha passage herein of Alpha passage, such as, 128) less value, less value is multiplied by 2, and deduct 0.5 (intermediate value of the 0.5 expression Alpha passage deducted, such as 128), finally the result obtained is appointed as the transparency of corresponding position.
When the information parameter of Alpha passage is positioned at described second channel interval in described texturing, the information parameter of Alpha passage in described texturing is utilized to control the high light expression effect of material.Shown in figure 5A to Fig. 5 C, in this example embodiment, the high light expression effect of material can be controlled by following function:
floatnode_8318＝max((_Diffuse_Texture_var.a-0.5),0.0)
Wherein, Node_8318 is the Node of stochastic generation; _ Diffuse_Texture_var.a variable represents the information parameter of Alpha passage, the information parameter calculating Alpha passage deducts the 0.5 (intermediate value of the 0.5 expression Alpha passage deducted, such as, value 128), and obtain value larger between this value and 0, larger value is appointed as the high optical information parameter of corresponding position.In this step, carry out determining step equally, to judge whether the information parameter of Alpha passage is positioned at second channel interval.
