I made some upgrades to my terrain streaming system: 1- asymmetric chunks/regions 2- circular vs. rectangular hysteresis zones 3- a "simulation window" that keeps a rect around the camera loaded in a contiguous block (instead of per chunk) of GPU RAM #procgen #terrain #streaming #gamedev #indiedev

Procedural Island Generation Part III is here! 🏝️ Blending of multi-scale noise layers and mountain distance fields will will transform the paint map foundation into beautiful terrain. Read the full post: #procgen #gamedev #indiedev #procedural #terrain

Testing my topology (DCEL/half-edge) library a little bit. Some Conway operators on a polyhedron and Catmull-Clark SubDiv. Simple matcap rendering in the viewport. #indiedev #gamedev #procgen #dcel #halfedge #computationalgeometry #topology

My library TopoKit is essentially a DCEL/half-edge wrapper. I've now added support for face/edge/vertex attributes, and propagation of those during mesh operations. #indiedev #gamedev #procgen #dcel #halfedge #computationalgeometry #topology

Mountain sharpness parameter to control peak steepness in procedural terrain generation: Transforms gentle hills into dramatic alpine ridges 🏔️ (Part of my ongoing series on procedural island generation). #gamedev #indiedev #procedural #terrain #procgen

New blog post: "Procedural Island Generation (II)" - Building on our Delaunay/Voronoi mesh foundation, we now create a low resolution base elevation map that defines the overall island shape. #gamedev #indiedev #procedural #terrain

In my infinite terrain streaming system I decoupled CPU load/unload (red) vs GPU activate/deactivate (blue) into two separate (intersecting) hysteresis zones. I also added a trait to support different zone shapes. #gamedev #indiedev #terrainrendering #optimization #graphics

New blog post: "Procedural Island Generation (I)" - Started a mini-series exploring terrain generation techniques inspired by the lovely mapgen4 project by @redblobgames. brashandplucky.com/2025/09/07/p... #gamedev #indiedev #procedural #terrain

[ fBm + ( 1 - Chebyshev distance to the center (squared) ) times a time-changing constant ] remapped by a water-ground 1D gradient. #gamedev #indiedev #procedural #terrain

I just finished my content-agnostic heavily-concurrent infinite-terrain system. I can now inherit from a (procedural) TerrainProvider class and everything else will happen auto-magically. #gamedev #indiedev #procedural #terrain #infinite

Poisson disk sampling constrained to another Poisson disk sampling. Valid positions for the large dots are constrained to positions from the small dots. #gamedev #indiedev #procedural #computationalgeometry #algorithms

Voronoi diagrams: circumcenters vs. centroids. 1: Using tri circumcenters. Classic/pure, angles are more abrupt. 2: Using tri centroids instead. Smoother, bubble-like regions. #proceduralgeneration #gamedev #computergraphics #voronoi #terraingeneration #indiedev

Little viz of Bridson's algorithm (blue noise). Each point (red=active) tries to spawn 1 new active point in its (orange) [r..2r] annulus. Green=success, red X=failed attempts. When no valid spots remain after k tries, the point turns blue (inactive). #geometry #gamedev #math #algorithms

Little viz of Lloyd's relaxation: iteratively move random points to their Voronoi cell centroids, naturally organizing into a hex-dominant grid. Gray trails show each point's journey from chaos to order. #voronoi #computationalgeometry #algorithms #math

Porting my little topology-focused library to RUST at the moment. #rust #rustlang #topology #programming #coding

Been diving deep into the fascinating world of terrain generation lately! @redblobgames and his incredible blog have been an absolute goldmine of insights and techniques. #terraingeneration #procedural #computergraphics #gamedev

Finally finished that spherical harmonics post that's been sitting in my drafts for 2 years. It's about encoding panoramic radiance with just a few coefficients. #computergraphics #rendering #sphericalharmonics #graphics #gamedev

Recently, I've been adding support for WebGPU and Vulkan (alongside OpenGL) to my homebrew engine. To inaugurate support for compute shaders, here's a side-by-side of classic DDA vs. Hierarchical DDA on a 256^3 voxel field. #WebGPU #Vulkan #ComputeShaders #GameDev

It’s fascinating how the velocity field highlights water streams tracing “still active” solution paths, while everything else falls silent. #gamedev #solodev #indiedev #customengine #physics #sim #CFD #FluidDynamics

Witness FLIP water solve a maze!! 🌊 Stress-testing my FLIP fluids sim (incompressibility, no tunneling, etc...). #gamedev #solodev #indiedev #customengine #physics #sim

Just finished a PIC/FLIP fluid‐solver subclass on top of my custom Eulerian engine! 🚀 Plenty of room to optimize, but I’m thrilled with how it’s coming together. 🌊 #gamedev #solodev #indiedev #customengine #physics #sim

I did participate in a game jam this weekend. If you have a chance to test the prototype I would like to hear you opinion / feedback: ditiemgames.itch.io/shaman

I threw some multi-threading into my Eulerian fluid sim, using Red-Black Gauss-Seidel for the projection step and parallelizing all the embarrassingly-parallel bits. So now mid-sized sims crank out way faster. 2048x1024 cells here 👇 #gamedev #solodev #indiedev #customengine #physics #sim

Why do planes fly? (A simplified explanation) High pressure under the wing pushes up, and low pressure above pulls up. This net pressure difference creates lift. This is a visualization of the pressure field in yesterday's wind tunnel sim. #gamedev #solodev #indiedev #customengine #physics #sim

I'm having real fun with my tiny simulated wind tunnel. :-P Here's a NACA 0012 airfoil under an increasing angle-of-attack, facing boundary layer separation (stall) at about 12-15 degrees. #gamedev #solodev #indiedev #customengine #physics #sim

This is the tiny "MAC-grid Eulerian fluid solver" I just made. CFD puts a big smile on my face every. single. time. #gamedev #solodev #indiedev #customengine #physics #sim

I've been writing some code for efficient traversal in voxel spaces recently. Here's a visual comparison between the bresenham line algorithm, and the Amanatides-Woo "Fast Voxel Traversal Algorithm". #gamedev #solodev #indiedev #customengine

Visualization of efficient DDA traversal in a heightmap (for voxel terrain raycasting). The heightmap is binned into a multi-level structure beforehand. #gamedev #solodev #indiedev #customengine

Visualization of my 2D/3D infinite terrain streaming system. The white rect represents the screen the player sees. As the player moves, regions of the map are uploaded/offloaded on-demand; nearby regions become awake/sleep for simulation (e.g., physics). #gamedev #solodev #indiedev #customengine

Crude visualization of my "multi-cache infinite terrain streaming kit". White: current player tile. Green: tiles around the player within radius. Dark vs. Light green: flagged to be fetched vs. already available. Orange: active recently but flagged to be kicked out. Purple: kick out timer went off.
