The French coding team Coyote Flux have revealed the latest in their line of interesting Amiga projects. "J Miner is a sequence-based photogrammetry package, allowing to correct and edit photos as if they were 3D models. The program is entirely written in PPC680x0, so both 68k and PPC versions are available." Read more about it here.

I think that they would need to redesign their website. It is very hard to read the pages with these backgrounds.
Is the software commercial, freeware ?

Oops, just assumed it since the main page says "Coyote Flux, Paris". :) OK, so they're Dutch, but currently based in France, right?

I didn't notice the Paris until you wrote about it.
Well I have no clue what this Paris is doing there ...
I remember listening to Coyote flux interviewing Bill Mc Even: They did not sound french at all. It sounded more german/dutch ...

This looks like it's based on "voxels"...

According to the webpage, this will not work on AmigaXL, Amithlon or UAE. Why?
Are they deliberately preventing the 68k version from working on an emulated environment?

In reply to Comment 9 (Detritus):
I guess they used some 68060 functionalities that are not available in emulators.
"Both versions are heavily optimized"
"High speed 80-bits floating point assembly engine"
Anyway warp3d is required ...

In reply to Comment 8 (Hm...):
I agree. Definitely looks like voxel graphics. Pretty cool idea they
are having there. If it runs fast enough, there might be potential for
a pretty innovative game using their engine.
Especially the aerial photo which was turned into 3d landscape looked
good. How about it guys? Anyone interested of doing a helicopter
warfare game on amiga with realistic looking voxel terrain?
It's been quite awhile since we've had anykind of fly/destroy games on
our miggies and I sometimes miss those... Thunderhawk and desert
strike kicked serious butt.

Clever, possibly even useful. Nice to know those guys are still at it, but I wonder what happened to Burning Rubber? Is it just me or do they imply that it can extract 3d info from a 2D source? If so, then I wonder if they have any clever algorithms/options to fill in the missing data?

It looks like the missing data becomes just dark patches, see the photo of the bedroom floor on the website.

In reply to Comment 14 (Budda):
I think that the dot render is just that - one dot for each pixel in the photograph, except with the inferred height added.
Hence the black spaces are where there are no dots because the height changed rapidly in the top down photo - the edge of the bed, for example.
I expect that the next step is to create a true 3D scene from a 2D image, with all the correct textures etc included as well, and mapped to the correct positions in the image.

Hello there!
First of all, we live in Paris, not "near Paris" and we will continue to live here. So we are a little bit of French now, but since we were born in Amsterdam we are also still kinda dutch... :-)
Anyway, there are a lot of exciting things going on with both the 3D engine and J Miner, but there is not a lot we can tell you right now.
Thanks for the comments, we really appreciate it.
Best regards,
Sharwin & Rakesh Raghoebardayal

In reply to Comment 18 (Coyote Flux):
Wow, Coyote Flux themselves dropped in! OK, so this thing can analyze moving frames and build 3d data from that? I want to know where you are going with this! Are you thinking of a game engine which can reproduce environments from 3d locations, or is it some kind of production tool? Do you have any plans for filling in the missing parts of the scene, like with symmetry, or filling in the volume as solid? I hope the site is updated regularly as this thing develops...

If you want to know more about how these sort of things are done, the keywords to search for are "optical flow", "image flow", and "3D reconstruction".
Basically, it involves figuring out how much things in the scene appear to move as the camera moves. The more it moves, the closer it is to the camera.
Once you've figured out a depth for each pixel, you can warp the image to any viewpoint by for example rendering them as 3D points or voxels.
There are zillions of algorithms for finding per-pixel image flow floating around the computer vision community. Probably none work well in all situations.
This isn't a magic solution to all your modelling problems, but it is neat that someone has implemented this on an Amiga.

Apologies for the useless country/nationality discussion.
I should ban myself from ANN ;)
I was wondering how fast was your program.
What CPU power would it need to be real time ?
Does a fast G4 with altivec would be enough to process in realtime
with a nice resolution ?

I might be totally off here, but wasn't the 6888x FPU "limited" to 64 bit? I really don't know...

Good to see there are still cool projects going on. With new Amigas coming maybe there will be more and more.. and more....:)

Yep, you are totally off and you don't know :)
PPC is limited to 64bit, that's what you read somewhere and mixed it up with 68k.

You cannot have views of surfaces that haven't been seen yet.

Great Project! I hope it will soon also support Multiimage reconstruction.
