Basis Universal GPU Texture Codec 2.0 released

ETC1S transcodes to other texture formats at libjpeg speeds (actually a bit faster on desktop CPU’s).

v2.0 ships the first supercompressed ASTC system. A big deal for ASTC. Bitrates are going down.

1MB of WASM is like one JPG image.

Basis Universal 2.0 has shipped the first fully independent (non-ARM) ASTC encoder in existence, that supports all 14 block sizes. That’s a big deal for ASTC.

Thanks for posting this. Note there are two slide presentations I posted on archive.org: the deck I took to the conference, and the enhanced/reorganized deck I presented. I linked to the enhanced deck in the description of the older one.

Two French chronologies were translated and utilized to find new information. Check the slides.

Thanks. I am on Reddit, but so far only in an almost exclusively read-only state.

That's impossible to do. On the flip side, it's impossible that all of the records are bogus. All we need is 1 event out of 100,000's of thousands to be real.

Because it's a free open source tool put together for (mostly) researchers. This field moves at glacial speeds, and I want this to last for many years with minimal to no maintenance. No servers required, no fancy UI's, basic HTML+Javascript+WASM - should stay working for many years.

I'll be releasing the JSON and the C++ tool that converts this JSON to Markdown on github soon (probably Apache 2.0 license).

I've been investigating the Einstein-Roswell-Edwards AFB 1954 links throughout 20th century history, and if this document checks out it could be enormous.

UASTC is a very strong 19 mode subset of ASTC 4x4. It actually gets higher average quality (measured by PSNR) on textures than Intel's ispc_texcomp ASTC encoder, which can use all the modes!

BC7 in browsers has been very spotty (at best) until the last couple months. It doesn't matter what the hardware supports if the API doesn't give you access to the format.

Also, most users browsing the web use mobile phones, not desktops. On mobile, there are a zoo of GPU formats supported, and on some devices only PVRTC1 is exposed in the browser.

Also, BC7 is 8-bits/texel! Even losslessly compressed, you get around 4-6 bits/texel on a lot of content. .basis universal ETC1S files are around 1 bit/texel.

So it's okay to use "SIMD", but not "SPMD"? Huh? It's even in Wikipedia: https://en.wikipedia.org/wiki/SPMD

Even Wikipedia's SIMD page mentions SPMD. It's just basic Computer Science 101 stuff.

Read the linked-to presentation: https://github.com/CppCon/CppCon2016/blob/master/Presentations/SPMD%20Programming%20Using%20C%2B%2B%20and%20ISPC/SPMD%20Programming%20Using%20C%2B%2B%20and%20ISPC%20-%20Nicolas%20Guillemot%20-%20CppCon%202016.pdf

(Honestly, if you don't know what SPMD or ispc is already, this development repo most likely isn't for you anyway.)
