OpenGL Alpha Flickering / gl.glDepthMask(false);

in Core Library Questions • 1 year ago

Hello,

im having some problems with OpenGL 3D and alpha.

I have a bunch of shapes that are stuck into eachother.

All of them are suppose to be transparent, but they arent.

at least only from one side or something like that …

if i use this little trick

gl.glDepthMask(false);

it kinda looks good, but i loose the perspective, kinda …

any other suggestions?

are there some other gl.X commands that could help?

Thanks

Try: hint(ENABLE_DEPTH_SORT)

Hello,

thanks for the reply!

Seems to help the flickering, but i guess it makes the shapes in space kinda unreadable.

i actually i guess this seems to be a classical clipping problem, without a certain solution.

if there are two shapes in the same space, there will be probably always problems to calculate which face is been drawn …

thank you!

If the problem arises because shapes/faces are in the same place, then a possible solution is to slightly move them - not by 1 but by something like 0.0001 - so they are no longer in exactly the same place.
