 |
|
Has anyone gotten alpha values to work. I'm having a bit of trouble, I'm doing it like this:
| Code: |
//before rendering image
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
glEnable(GL_BLEND);
//render image
....
glDisable(GL_BLEND);
|
The image, does have alpha and we are passing it into glTexImage2D as glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, 64,64, 0, GL_RGBA, GL_UNSIGNED_INT_8_8_8_8,data);
But I dont see the blending. Any ideas, has anyone tested this functionality?
Thanks again
Jeff. |

| It should work, but there may be bugs. I've got a series of patches at http://goop.org/~jeremy/psp/pspgl/ which improve texture handing (including implementing texture objects), and I can certainly get alpha-blending working properly. Look at the "series" file, which says what patches to apply in what order. |
