GRID Begins

Third simulator in the lineup, and this one’s a spacetime mesh, so instead of watching an object move through space you’re watching space bend around it.

• Started with a plain grid of points, then had to figure out how to actually pull them toward a mass without it looking like noise. Went with an inverse square-ish falloff (not GR accurate, more of a stylised well for now) and it clicked visually with barely any tuning.
• The annoying part was stopping the mesh folding back through the mass itself when you drag it in close. Lines were crossing over each other and it looked completely broken. Fixed it by clamping the pull so it eases off the closer you get instead of spiking, simple fix once I saw what was actually happening.
• Kept tonight deliberately small, one grid, one draggable mass, nothing else. Wanted to prove the warp looks proper before building anything on top of it (that went well for g-lens lmao)

Next up: strength slider and a reset button, then a second mass to see how two wells interact with each other.
