Hi,
After playing about 1 hour (1 more) with the sceBlendingFunction without getting the results I like, I have decided to post again about blending.
What I would like to get is something like Cs * Alfa + Cd * (1-Alfa), easy....
My Pixel Buffer is 565, and the image I want to blend with the pixel buffer 565 too now. I have thing about converting de 565 to 4444 and use alfa in my vertexes, Is this what everyone would do in this case?.
P.D. With the srcfix and dstfix parameters of blend function I got some kind of blending but colors where screwed, so this is not enough for me.
Thanks in advance,
HexDump. |

Here's what I do, don't know if this will help you or not:
On init:
| Code: | sceGuBlendFunc(GU_ADD, GU_SRC_ALPHA, GU_ONE_MINUS_SRC_ALPHA, 0, 0);
sceGuEnable(GU_BLEND); |
When I set the texture, I set my modulation accordingly:
| Code: | if (pMaterial->has_alpha)
sceGuTexFunc(GU_TFX_MODULATE,GU_TCC_RGBA);
else
sceGuTexFunc(GU_TFX_MODULATE,GU_TCC_RGB);
|
For vertices: alpha value of 0==completly translucent, and 255==completly opaque[/code] |
