About Postcard
Postcard is a short playable technical demo where you walk around photorealistic 3D scans of real world places.Each environment in the game has been captured from the real world including its lighting, ambient sounds, and even the crunches of gravel and steps on concrete were recorded from the real location.There's not a lot to actually do in the game, but if you love pretty environments and want a hands-on peek at how scanning tech can make something far more immersive than a 360-degree video, then you might enjoy Postcard.
Where are these places?
The places you can currently visit in Postcard are in Canberra, Australia.We might be able to add some other locations in if there's interest :)What can you do in the game?
Choose from a list of 10 different characters, then choose from a list of 7 locations.Once you're in the location, you can walk, run, jump, and orbit the camera around. That's it. Nothing crazy on the controls or features, but some very stunning real-time visuals and reality capture going on.Underlying technology
For the people who love behind the scenes tech details, the environments in Postcard are created from a mixture of traditional photogrammetry and mesh construction for the terrain shapes and shadow catching, as well as gaussian splats for the beautiful visual layer. About 15-30 minutes of continuous video of each location capturing as many angles and details as possible, then processing through mesh photogrammetry and gaussian splatting, plus a lot of manual alignment and turning into playable areas. Shadow areas are hand-masked to avoid casting a second shadow over what was already present and baked in from the source scan. Spherical HDR photography in the middle of the scene for lighting, as well as walking and running on all the surfaces on site with a microphone near our shoes!Handmade, no Gen AI.What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
Grand Theft Auto: Canberra Pros: Visit the ACT without getting extoted by the National Capital Authority for parking. Cons: No Penis Owl DLC I could have really done with an inverted control scheme. And for some reason I couldnt use the enter key when in the menus either. Great work all the same, I enjoyed checking it out.1 found this helpful
Cool tech demo, got me thinking of other locations that would be interesting to visit. Everything is really smoothly done, the walking/running, the terrain, the boundary excited to think about the future uses of what is on show here. Love the little things like the spatial water fountain sounds - just let me get in and splash! Loads and runs perfectly on SteamDeck using Proton Experimental1 found this helpful
I tried this on my Steam Deck, and I have say that I'm not that impressed, nor do I think this is the "way of the future". Many areas were lacking clear detail, the characters clipped various objects, and even though I know this was a demo, it would've felt more intuitive if there was stuff to interact with. Don't get me wrong; these guys probably took quite a bit of time to take the images needed to stitch this together, and they did the best with what they got, but this demo really needed more time to cook. That said, if more gets added, I might change my recommendation. For now, though... I'd pass on this one.
This game got good graphic, but it's very small map and nothing to do, so if developer do something in future like more interesting views in world and some explore places with some quests to do with like telescope or find some things on those places, then i will maybe change my mind to positive review.
It's not going to mean a lot to anyone that isn't a local and recognises these spots. Regardless, it's an interesting view on what Gaussian Splatting can achieve. I personally would have preferred a first person perspective to a third person though. Runs well on Linux with SteamPlay
