Rendez-vous in Montreal (1987) - one of the first examples of skeletal animation: https://www.youtube.com/watch?v=vuvvv7Bie4U&feature=youtu.be … https://en.wikipedia.org/wiki/Rendez-vous_in_Montreal …

Played some Age of Empires Definitive Edition multiplayer for fun. MP is still pretty active and I got into a game quickly.pic.twitter.com/ztLUebOq4O

Andrew sent me his improved PVRTC encoding. So good I did a doubletake.pic.twitter.com/qvZzwgU19j

Here's a real-time encode to PVRTC (27.16 dB) and high quality BC1 (44.15).pic.twitter.com/4HMcIU4PVH

This artificial test image (from the Dava engine) is tough for PVRTC. Left is original, middle is my encoding (44.3 Y dB), right is PVRTexTool (37.89). Those artifacts on the 1 and 0 are so annoying.pic.twitter.com/S3dyfLod4e

If you ever were sitting up late at night, wondering if a grayscale H ramp looked better in BC1 vs. PVRTC, well here you go. BC1=51 Y dB (left/first image), PVRTC=60.2 Y dB (clamp addressing).pic.twitter.com/slyS4S8UOO

Torture testing PVRTC. First image is PVRTC and the rest are visualizations (low/high endpoints and 2-bit pixel modulations). I'm beating PVRTexTool for PSNR/SSIM but visually my results look worse to the eye.pic.twitter.com/PISusIYnfx

If you're curious how this was encoded into PVRTC, here are visualizations of the low endpoints, high endpoints, 0-3 modulations, and whether each block used punchthrough (3 color) alpha or not. (I processed all these images using http://ravenworks.ca/twitimagefix/ )pic.twitter.com/piIJ4KjSXU

Just achieved a 60.5 dB [0,255] H ramp with my experimental PVRTC encoder. Left is PVRTexTool best quality (46.8 Y dB), right is the new lookup table based algorithm (60.5 Y dB). This is the best H ramp I've ever seen in PVRTC 4bpp from any encoder.pic.twitter.com/U26UP03fWB

Was watching the old 90's sci-fi series "Earth: Final Conflict". It takes place in the 2020's, but it's loaded to the gills with bulky CRT monitors. You can tell the age of movie/TV productions by paying attention to the monitors used. Except for "2001" - Kubrick got it right.pic.twitter.com/XphFWe0sMq

Real-time PVRTC1 encoding is an interesting problem. The first pass computes endpoints by computing per-block RGB bounds, the second computes modulation. I really wish colorB's blue channel had 5 bits (vs. 4) - 4 bits for blue leads to slightly blue tinged ramps and more banding.pic.twitter.com/FqVRtYiYNs

I added cascaded shadow mapping to CS:GO (which was a ridiculously hard thing to do in Source1). Players have found the best "Shadow Spots" on various maps, which gives them slight advantages. I think this is awesome:https://www.youtube.com/watch?v=OOQ32mhHCy0 …

Been watching the original Star Trek TV series remastered. It's surprisingly good although the writing quality varies a lot. The new FX are good and don't stand out too much. The FX are what could have been done in the late 80's.pic.twitter.com/gMsCRSTGG0

Non-RDO BC7 encoding with random codec params, with more samples vs. my last tweet. The Pareto frontier is starting to become visible now. The test texture contains random blocks picked from thousands of textures in my corpus.pic.twitter.com/CbYezNCMD6

We're now feeding random codec configuration parameters into our non-RDO BC7 codec and plotting the results. Partially for testing, but also to find good settings to use for the various speed vs. quality profiles.pic.twitter.com/JK5z0oZkoP

Our non-RDO BC7 encoder in Basis is now faster and higher quality than all other CPU BC7 encoders that I've tried (NVTT, Intel's ispc_texcomp, MS). I just put in several mode-6 only optimizations, so we're now 19% faster than ispc_texcomp's ultrafast profile at higher quality.pic.twitter.com/jhEoV3atst

I'm optimizing mode 6 encoding in our vectorized BC7 encoder. Trying to optimize the output block packing function - clearly there's a problem.pic.twitter.com/hIK8whuQIU
