I've always loved 3D sterescopic images and decided today to try making a 3D stereoscopic map. It was just a test map, but frankly, it was a pain in the butt.

So has anyone done these before and have any advice or shortcuts?

Arcana's done some stereo work. Samples starting at about post #6 in this thread:

He also posted a tool of some sort in there, but since stereograms give me a headache, I haven't had any desire to look at it.

Wow! Your Anaglyph came out really well! Just to show how big of a geek I am, I actually have a pair of anaglyph glasses setting next to my computer and they are not made out of paper. Anyway, well done!

That gives me some ideas for other stuff. I wonder how a game played using anaglyph images via MapTool would be...?

Wow! I don't have 3d glasses so I was looking at the parallel stereoscopic. Very cool! I would love to see some complicated dungeon maps done this way. Talk about making the game world come alive. VERY cool stuff!

In most 3d applications you can render stereo images...I create a camera rig that consists of two cameras linked to a dummy that I move around...the cameras are properly spaced for the scale of the scene and I just move them around and render the view from both cameras and use my stereogram maker to paste them together quickly.

This woudl be a quick and easy way to render out a complicated map without having to actually think about the stereo process.

I don't know why I didn't grab that the first time around, but I have it now. ;)

Did you do those by hand?!?

Thanks for the link, Arcana. I'll check it out...

Well, my hand was on the mouse. Does that count? :)

I meant - "drew the two views by hand as opposed to making a 3d model you took stereo views of..."

I'm impressed!

There is actually a very easy method that can be used to create anaglyphs in PhotoShop I'll have to see if I can remember it and post it up here for anyone that might be interested.

Here's a second test. I wanted to see if I could incorporate some textures and some stuff from my dungeon map library.

As it turns out, it was actually easier this time around. I paid strict attention to the grid and kept track of the offset deltas for each layer.

Next step will be to try a full dungeon level...

[Edit - That's weird. The cyan color keeps going off a little bit after it's uploaded. May take some experimenting to get it right...]
[Edit - It looks like it's the saturaration that's getting fudged when I upload it. I doubt the problem is inherent to this site (which is running vBulletin), so it's probably something to do with Internet Explorer. Maybe my local settings... Anyone else getting off colors?]

Cyan is perfect for me... it is the red that is off.. Could be my monitor. That is why I prefer the cross-eyed version (reproduces colour better, too)

Has anyone tried a chromadepth map like these here:

The glasses that come with the Crayola 3D chalk are the right kind, and will apparently work on any image of this type.

I'm intrigued! How did you find out those glasses would work? The one link shows gel markers being used. Do those glasses come with the markers? I wonder where you can get those?

I found it out in a review of the Crayola 3D chalk in a parenting magazine (excuse me, but my life stage is showing :P). They said it worked well with crayons, gel markers, computer screens (and has a weird effect with movies that have high saturation... think Dick Tracy)...so long as the background is dark/black.

That is fascinating. I may have to guy up to Toys R Us this weekend...
