Hi
I’ve 2 images. Now without special the glpoint draw is alway on top. I only can see the below with transparency. alpha 0.5 works but doesn’t look very good so I wonder how to put the below above the glpoint draw image. should be possible with glBlend? but I cannot figure the right settings. Now I use :
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
which only works with alpha transparenzy 0.5
Many thanks
Michael
Draw the point further away in Z, until it is “below”.
Or I did not understand what you want to do.
No only 2D
I’ve found this but still haven’t found the solution. I don’t know which image is back or front…
