"Voxel physics in a nutshell. A point inside a voxel is pushed towards the closest surface. The closest surface can be simply obtained by taking the dominant axis (some GPUs have a cubeface instruction for that)"

"Started building a voxel system for HypeHype. It's using 4x4x4 (uint64) voxel bricks. Not a full 64-tree like my hobby project design. Just a single level indirection similar to virtual texturing"

"I am considering a brick-map style voxel system for HypeHype. Each 1m3 brick would point to shared subtrees (= DAG). A bit like the Unlimited Detail demo back in the day. We wouldn't need that much detail in the bricks. Aiming for Nintendo game look instead of realistic look"

"1. Build your own programming language X. Build a game engine on top of that language X. Build your game on top of that engine if X and X didn't consume your whole life. We have been waiting this game for a long time. It's nice that Jon had the time to do it"

"Asked Codex to change my WebGPU terrain ray-tracer to use gather instead of texture load (for the DDA trace). It changed the terrain pixel format to fp16 from uint16. Much more quantized. Equivalent of XX bit at height 0.51.0. Wondering why it didn't use unorm16"

"@28delayslater Skill issue. You need to quickly toggle back/forward gear to gain speed. I don't own a Tesla so I don't know it it's easy to do on a Tesla but on a VW EV you simply wiggle the D/R toggle. Been in the same situation couple of times and that works"

"@_iamtolulope "-" has overloaded semantics in maths. It can either be the subtract operator negate or a sign (negative number). Power of two of -X is of course XX. But negate of XX = -XX. And subtract by XX is subtract by XX is -25"

"@mweinbach Yeah there are certainly advantages: 5K resolution and brighter HDR with no brightness pumping. But let's see what is the latency trade-off. OLEDs panel pixels are extremely responsive and 120Hz - 240Hz is a small improvement for fluidity too. I wait for measurements"

"Yes I have heard about that. 200km is XXX minutes of driving at 120km/h. If you start at XXX% and drive to 0%. That's not practical. 10%-80% is the recommended range. Battery wears out 2x faster if you charge to XXX% and the last XX% takes as long to charge as the first 80%. Thus you charge XX% on every stop = between XX minutes. Charge every X hours is not realistic at all"

"The ambient looks flat on the left side of the screen so I started designing a new sky visibility tech for the WebGPU terrain renderer. Realization: Voxels only have X directions. Sides top and down. Terrain system doesn't have down direction. We can do HBAO-style algorithm for the 8192x8192 terrain heightfield at startup. Instead of calculating one AO value we split the AO to four directions as we have four side directions. Four values can be stored to RGBA8. Since all side angles open from the top direction we can combine two sides as one opening angle. If we view it from the top we need to"

"@casualgamerqc @Jerroudi_Yass @Prakhar6200 @Pretentious_A_ @sukunaa420 @Sankew06 Hyperthreading is very important for servers. X64 designs cater desktops and servers. Traditionally laptop SoCs have been just variations of desktop chips but Lunar Lake is more different. Which brings big improvement for idle power consumption"

"WebGPU is awesome but not perfect. WebGL2 offered us XX year old DX9 feature set with some limitations. WebGPU offers us XX year old Vulkan XXX feature set with some limitations. There's no SM XXX style indexable descriptor heap (or descriptor indexing) there's no 64-bit GPU pointers (or 64-bit integers/atomics) descriptor sets are immutable (and there's no API for temp descriptor sets - Vulkan has resettable pools) there's no persistently mapped GPU memory for efficient data upload the async map API is cumbersome to use CPU mappable resources can't be directly loaded by shaders (need a copy"

"HLSL only requires 4-byte binding offset alignment and 4-byte load alignment (even for load2 load3 load4) which results in bad codegen on Nvidia for example (they can't emit wide loads). That's not a flaw I want to have in any new API design"

"It's sad that HLSL loadT didn't fix this flaw. It requires only alignment for a single element of a vector. For example float4 = X bytes half4 = X bytes. Microsoft optimized for AMD console hardware. But DirectX runs on Nvidia Intel and Qualcomm too"

"Lidar is just a sensor type nothing more. Various sensor data can be fed to train the network. All sensors are getting cheaper. A lidar system can be soon mass produced for $1000 in China. I expect the AI network inputs to change many times until we reach the optimal setup. I don't like polarizing discussions about different sensor types or different network topologies. People are trying to boost their favorite company perception or stock value in the social media. Feels like the console wars back in the day. Better to let various tech co-exist and evolve. We don't know the best solution yet."
