Not that large. The JS glue code for the VR web page referenced above is 48 KB, including WebGL, WebXR, Fetch, etc.

The "native WebGL bindings" still call into JS. Desktop GL emulation is just a layer on top OpenGL ES if, for example, you're still using OpenGL's fixed function pipeline (deprecated 13 years ago.)

You're correct. WebGL does require extra validation compared to native GL, but it's effectively the same API as OpenGL ES 2.0/3.0 and Emscripten handles the translation from C/C++ for you. There's some overhead but

Is this AR/VR? It looks like 2D circuit schematics.

As a counterpoint, I've enjoyed building VR on the web using C++ (with WebAssembly/WebGL/WebXR) and not having to touch the DOM or JS, see: https://twitter.com/nobbis/status/1425266634982248451 Bene

Yes, different failure cases (purely vision can't tell the depth of a plain white wall) but there are orders of magnitude more pixels in regular cameras. Apple's LiDAR produces a 256x192 depth map, but its RGB cameras run at 1920x

Cubify was a rebranded Structure Sensor, which was a Primesense camera, which was the original Kinect (that Apple bought in 2013.) It used structured light: project a static pattern of infrared dots and then measure parallax using an infrar

FYI, NZ is multiple islands the size of the UK with a population 15x that of Iceland.

How does the accuracy of your system compare to ARKit’s people/skeleton tracking with the LiDAR Scanner in the new iPad Pro?

His personal blog post has eight obtrusive ads plus a Donate button (to an engineer in finance in London.) I get the sense the author's deliberately stirring controversy.

NZ was a few days after Germany, yes, but it's a very isolated country. Germany locked down after almost 100 deaths (and 20,000 cases.) NZ locked down as soon as community transmission was detected (2 cases out of 50 total were untrace

As a Kiwi living in NYC, I'm impressed by the "go hard, go early" approach the NZ government has taken, compared with the delayed response here. NZ also has easily enforceable border control (surrounded by the Pacific ocean)

It was the first self-driving car project to cause established companies to take notice and start investing heavily, kickstarting the industry, which was my point. Other co-founders, yes, but Anthony was overall product lead. The article go

Got it. If you’re just listing open source photogrammetry software, there are many more you can add, e.g. Regard3D, OpenMVG.

I find COLMAP has better dense depth maps, a more configurable pipeline, is cross-platform, the code is solid, and the accompanying research is principled (it takes a Bayesian approach to stereo matching.) What aspects of these make them gr

by nobbis 7y ago
Range is too limited, it's front-facing (can't see what you're scanning), and the OS-provided SLAM system isn't available (so tracking error accumulates.) Issues that will disappear in the long-run, of course. One startu

Yes, we support Laplacian filtering of the level set prior to meshing in the SDK (plus other mesh smoothing techniques.) There are trade-offs involved.

Another great free alternative is COLMAP ( https://demuc.de/colmap ). And for those interested in doing this on mobile in real-time, we've just released a beta SDK ( https://abound.dev ) that lets you add real-

VIX is a variance swap, so a "CryptoVIX" would move in line with the expected short-term realized volatility of a basket of cryptocurrencies, not their price. It'd certainly be possible to price such an index (replicating str

Photorealism (or "better rendering") doesn't mean perfect imaging. You can model the radial distortion, rolling shutter, Bayer filtering of cheap webcams in 5 lines of code. A better simulation is closer to reality, not clos

by nobbis 9y ago
It's the opposite. Simple rendering makes pose estimation harder, not easier - texture and shadows resolve depth ambiguity. So it's easier to show you've "closed the simulation-to-reality gap."

Trust Google to look at their c. 1993 gouraud shaded, untextured renderings without shadows and conclude "let's use deep learning to make it look realistic!"

I commented here on Tango 3.5 yrs ago: "remains to be seen if Google can persuade cellphone manufacturers to include 2 special cameras + 2 extra processors in their future devices." Looks like that was the case. It appears the AR

We're planning to bring occlusion to ARKit with Forge. The accuracy can't match a depth camera, but still plenty of use cases. Here's an example on a Pixel: https://www.youtube.com/watch?v=K9CpT-sy7HE

Economists were modeling the economy using circuits in 1949 (see MONIAC), before the Integrated Circuit was even invented.
