PosS16Through: Treat Z as unsigned.

[hrydgard]

@unknownbrackets This takes care of both the JITs as well.

Wonder if this will help Phantasy Star Portable 2.. Proceeds to try it..

[hrydgard]

Probably not unless you also add Unknown's little Z hack? (z += 0.00001 in the vshader)

[thedax]

Do I just add it anywhere in GenerateVertexShader? Sorry for going off-topic, I won't post anymore about it after this. :)

[hrydgard]

Try adding this on line 367 (after gl_Position = u_proj_through * vec4(position.xyz, 1.0);)

  WRITE(p, "  gl_Position.z += 0.000001;\n");

and possibly vary the amount of zeroes, heh.

[thedax]

Unfortunately, it didn't help, so that game's issue is elsewhere. Thanks.

I also tested #4836 as it has similar depth issue but didn;t help yet

[ThePhoenixRises]

May I ask a Noob question, What does this do in terms of fixing?
And also why is it Unsigned, does that make much difference?

[hrydgard]

It may fix some depth issues, if we were interpreting the Z values given by the game wrong.

[ThePhoenixRises]

Sorry you will have to put into simpler terms LOL, I am that Noobish.
Do you mean as in the different graphics layers are in the wrong order, like some sprites maybe in front of an object, but in the game on PSP should be behind it.

[hrydgard]

Yeah, pretty much. There are no graphics layers on the PSP though, things are sorted by depth buffer (google it).

[unknownbrackets]

Looks good to me.
