it's perfectly ok to simulate 3D pathfinding on a 2D grid. It's all about edge detection: mark cells between different elevations as unwalkable. Mark cells as walkable to create a "ramp" between levels. Keep a height map to vertically displace units. PF simulation remains 2D

Marching squares is a classic algorithm for constructing contours of a 2D scalar field. It is used to create visualizations like topographic maps. Grid cells are matched to simple polygons based on which of their corners are above or below a threshold.

GTA 6 Fact #4: - The minimap features 3D buildings, bridges elevations, and water levels. - There’s an option to switch to a 2D view. - You can also use a compass, similar to RDR2, instead of the traditional radar.

We built a 3D node just for Astra. Generate 3D faster in FLORA, iterate between 2D & 3D directly on the canvas, and export directly to Blender.

RPG Maker U2U has been officially revealed which will allow users to create HD-2D-style games. Called "P2D" (Perspective 2D), users can create 3D depth and rich effect expression to conventional 2D maps. 2D assets from previous RPG Maker titles can be used as map tiles for decoration, and more than 100 ready-to-use P2D maps are included. #rpgmaker

It's the future it's possible that we'll use cells plus silicon for compute. In this experiment, scientists used a mouse brain organoid (brain-in-a-dish) to play a video game, showing living cells can solve digital tasks. Reaching 46% proficiency in a CartPole simulation.

Working on pathfinding. It's based on the A* algorithm. For testing purposes I can mark a destination and the algorithm tries to find the best path. Progress is visualized by small cubes. The yellow cubes mark the current best path.

There is a clear link between vaccines and autism. “It's really a toxic overload of the cells. These children that are more likely to regress into autism have impaired detoxification pathways.” Watch as Brian Hooker, PhD breaks down how vaccines can cause autism on Health Freedom Radio. ⬇️

2D or 3D ? It’s wild to be able to create such precise 3D models with a 2D visual using Tripo or Meshy. They aren’t 100% perfect, but I’m going to refine them in Blender with the help of Claude.
