Working on Sparse Volumetric Light-maps. Thanks to CynicatPro🎃 for pointing me at Unreal's version. In a nutshell it's just another sparse voxel data structure. My implementation is, no doubt, different from Epic Games Store's own. I'm using 4x4x4 probe grid with intermediate nodes having very wide branching factor of 64 as well (4x4x4). I liked the parameters that Unreal is using, of limiting both total memory as well as the lowest level of detail, which is common in sparse grid implementations. Here's Bistro scene with just 1Mb limit. This is roughly equivalent to a 512x512 lightmap texture in 2d, except surface light maps require unique UVs and you typically get very little detail out of 512 resolution texture with a lot of light leaking. There is also no directional response. My implementation encodes second-order spherical harmonics for each probe (9 coefficients), encoding RGB channels as RGBE9995 (4 bytes). So far only worked on the structure, actual bake is yet to come. I've been eyeing sparse voxel structures for a while now, and have been studying them roughly since the GigaVoxel paper by Cyril Crassin but never really implemented anything for the GPU before. I was always the BVH-kind of guy. It's a fascinating topic. --- Stats for the scene: --- Total memory usage: 1.000 MB Node count: 609 Unique probe count: 24,025 Probe reuse: 38.36 % Unexpanded nodes: 15,714 --- Again, note that there is no GI going on here, only the structure of the probe tree and the algorithm for building it from a given scene.

Flexible Isosurface Extraction for Gradient-Based Mesh Optimization paper page: This work considers gradient-based mesh optimization, where we iteratively optimize for a 3D surface mesh by representing it as the isosurface of a scalar field, an increasingly common paradigm in applications including photogrammetry, generative modeling, and inverse physics. Existing implementations adapt classic isosurface extraction algorithms like Marching Cubes or Dual Contouring; these techniques were designed to extract meshes from fixed, known fields, and in the optimization setting they lack the degrees of freedom to represent high-quality feature-preserving meshes, or suffer from numerical instabilities. We introduce FlexiCubes, an isosurface representation specifically designed for optimizing an unknown mesh with respect to geometric, visual, or even physical objectives. Our main insight is to introduce additional carefully-chosen parameters into the representation, which allow local flexible adjustments to the extracted mesh geometry and connectivity. These parameters are updated along with the underlying scalar field via automatic differentiation when optimizing for a downstream task. We base our extraction scheme on Dual Marching Cubes for improved topological properties, and present extensions to optionally generate tetrahedral and hierarchically-adaptive meshes. Extensive experiments validate FlexiCubes on both synthetic benchmarks and real-world applications, showing that it offers significant improvements in mesh quality and geometric fidelity.

🚨 EXPOSED: Clinton Foundation's DIRTY Secrets UNRAVELED in Bombshell Leaks! 🚨 IRS & FBI Probes SHUT DOWN to Protect Hillary's Pay-to-Play Empire? You Won't Believe the Cover-Ups! Folks, the floodgates are OPEN! Thanks to whistleblowers + declassifications by Kash Patel & Pam Bondi, John Solomon just dropped MEGA docs implicating the Clintons BIG TIME: 🔥 2016 FBI Nightmare: Declassified timeline shows Obama DOJ’s “SHUT IT DOWN” order on THREE FBI probes into Clinton Foundation’s pay-to-play scams! – Foreign gov’ts funneled MILLIONS for State Dept favors while Hillary was boss. – Agents in NYC, Little Rock & DC had SOLID leads. – Andrew McCabe & Sally Yates KILLED it pre-election. Kid gloves for Clintons, brass knuckles for Trump! 🔥 2019 IRS Bombshell: Criminal tax probe LAUNCHED after whistleblowers John Moynihan & Larry Doyle exposed the Foundation as a “FRAUDULENT ENTERPRISE”! – Acting as foreign agent – Tax evasion – Commingling Bill & Hillary’s personal cash with “charity” funds – Raking in $2.8B! IRS was READY to roll, even called it a full fraud... then SUDDEN STOP. “Can’t talk about CF anymore.” Excuse? “No resources.” (Same IRS that targeted conservatives!) Pure protection racket for Dem elites! 🔥 Comey Redactions REVEALED: Unmasked memos show ex-FBI chief’s secret media mole, Daniel Richman, leaking to NYT to shape Russia hoax & force Mueller probe—ALL to shield Clintons? Comey’s lieutenants (Strzok, Page) briefed press, ignored evidence against Hillary’s emails. Govt HAD tons of dirt but REFUSED to pursue! This is the SMOKING GUN on how the swamp protected the Clintons from justice! 👀 Grand conspiracy probe incoming? ⚡ Share if you’re SHOCKED—we’re finally seeing the TRUTH!

CLINTON FOUNDATION DOCUMENTS RELEASED. The complete declassified Clinton Foundation meeting timeline. 1 of 6 pages. It's time for indictments. This is what the FBI was trying to investigate but was ordered to stand down and SHUT DOWN all investigations which then allowed the Clinton Foundation to operate a "Pay to Play" political bribery and money laundering operation without the fear of being indicted. The email investigation, and the Clinton Foundation investigation were both shut down while at the same time trying to go after Trump for false, made-up charges. This is the weaponization of the DOJ and a two-tiered justice system. They knew they were protected. The question you should be asking yourself is why do the Clinton's have so much power and what else is the Clinton Foundation involved with, especially when in comes to Haiti, the Beyond Borders Organization, USAID, ActBlue, Soros, child trafficking, etc.? Here is the Declassified Timeline on Clinton Foundation Investigation: - 2017 Memo Declassified: FBI Director Kash Patel’s release of a 2017 memo exposes deliberate political sabotage of the 2016 Clinton Foundation investigation. - Yates’ Shutdown Demand: Deputy AG Sally Yates, without any explanation whatsoever, ordered agents to “SHUT IT DOWN” in March 2016, inexplicably derailing the probe into alleged Clinton Foundation corruption. - McCabe’s Iron Grip: Deputy FBI Director Andrew McCabe repeatedly blocked investigative steps without his approval, strangling the probe’s progress. - DOJ’s Early Sabotage: By February 2016, the DOJ signaled refusal to support the investigation, with New York prosecutors stonewalling by August. - Pay-to-Play Evidence Ignored: The probe targeted potential pay-to-play schemes, with evidence linking foreign and U.S. donors to favors from Hillary Clinton’s State Department. - Investigation Dragged and Buried: Roadblocks delayed the probe past the 2016 election, with DOJ citing statute of limitations to justify closure. - FBI’s Double Standards: While the Clinton probe was smothered, the FBI aggressively chased the unfounded Trump-Russia collusion narrative. - Justice in Motion: Attorney General Pam Bondi’s new strike force and grand jury, backed by current and former agents, now probes these law enforcement abuses. Everything is being laid out for you to see and judge for yourself, this is called transparency so when the trigger is pulled you know exactly why at what you were being lied to about over the last decade, plus.
