MCShapes 3D Engine
Flawless 3D voxel blueprints for Minecraft mega-builds
Building massive spheres or domes in Minecraft? Traditional 2D generators use confusing "ghost" layers that cause misplaced blocks. MCShapes is a free, interactive 3D voxel engine built to solve this. It features high-contrast layer tracking, a "Hollow" mode for survival bases, center-axis alignment, and exact material counting. Stop guessing your curves and plan your mega-builds in full 3D!
Hey everyone.
I built MCShapes because I was sick of using 10-year-old 2D web tools to plan massive 3D builds in Minecraft.
If you've ever tried building a 50-block wide underwater dome or a floating planet, you know the nightmare: one miscounted block at the base means your entire roof is lopsided hours later. Existing generators rely on a transparent "ghosting" effect to show layers, which is visually confusing and causes constant mistakes.
To fix this, I built a dedicated 3D voxel engine that runs smoothly in the browser.
Instead of guessing curves, it gives you:
* High-Contrast Layers: Active blueprint in Yellow, completed layers in Blue. Zero visual overlap.
* Red Axis Alignment: A 3D crosshair to ensure your roof always aligns perfectly with your base.
* Hollow Mode: Strips interior mass to calculate the exact block count for the outer shell.
It’s completely free. I'd love to hear your feedback on the 3D rendering performance, or let me know what shapes I should add to the engine next.
