I want to know what exactly the alpha is. Is it the color of the transparency or the value of the transparency level.
For example:
GLubyte RGBA[1][1][4] =
{ { {255}, {255}, {255}, {255} } };
If I do this as oppose to this:
GLubyte RGBA[1][1][4] =
{ { {255}, {255}, {255}, {128} } };
Would the first example but full color white or would the white by transparent or would the second example be kind of like a window. You can tell that it is there but you can still see through it.
There may be a problem with the array but this is theory. I do know that I would have to enable GL_BLENDING before I work with this but I hope to understand the alpha before I start working with PNG files or if I don’t, be able to create better arrays so that my game would work better.
