Version:Size:
As seen in SatoshiMcCloud's game "PLANE2SOLID", it is possible to create a 3D effect on the graphics screen using a virtual parallax barrier. This tutorial explains how to create the virtual parallax barrier using the SMILE tool, how to draw it to the screen, a simple way how to control what each individual eye sees, and even explains how to create 3D effects. Sorry the screenshots are kinda lame. The examples I provide in the tutorial actually require you to be looking at them through a 3D screen. There's not much I can actually show in the way of screenshots. It's mainly just text and a few examples. Edit: Updated with a section explaining how to make your own VPB with the SMILE tool, rather than just using one provided to you.

Instructions:

Just run the program ".RUNME". It explains itself. I merged the files from the Microphone/Audio playback tutorial with this tutorial. You can view that tutorial by running the ".RUNME2".

Wow, this was helpful! Thank you for making this! :) That Red-Blue screen is really uncomfortable though....

Haha, yeah. I just thought that would be a really straight-forward example. I'm glad you found this helpful, though! C:

It's a good example , just painful ;) Do you think there is a way to do this with console characters instead?

Not to my knowledge. If you just want the characters to be above the graphics screen, you can use the LOCATE command. If you want different characters to have different depths, you could do it, but you'd have to write your own library.

I mean instead of using BG as the parallax barrier use a |||| character type thing instead? I might try this later.

I don't think so. The "|" character doesn't actually appear as a straight line, and you can't draw them with separation of only 1 pixel.

Ah, okay. Would there be any benefit to using FONTDEF over BGFILL?

If you want different characters to have different depths, you could do it, but you'd have to write your own library.
The z-coordinate for LOCATE isn't the offset of the entire screen, it's the offset taken by that particular character cell. Try this to see what I mean 
LOCATE 0,0,1024
PRINT "TEST"
LOCATE ,,-256
PRINT "TEST AGAIN"
If you knew that already and you meant something else, sorry, my mistake.

Ah, okay, my mistake. I'm used to using the graphics screen, I only use the console screen for basic debugging and I've never touched the sprite screen before or the background screen except for drawing the VPB. :P

Minxrod, I tried your idea and it works! You can use the console screen for this. I might add this to the tutorial since it's a method that doesn't require an external file. You can literally draw the VPB with a single command: 
FONTDEF 0,"00010000"*32
That sets null character to a character with a bunch of lines, and if the console is cleared, that's the entire screen.
