Glue3D

Initial window introducing the user to Glue3D

Glue3D is a 3D engine made in Scratch, developed by GL00B. The engine has many features, such as textured rendering, model editing, bone keyframe animations, scripting, file management, as well as exporting a final build of your game.

The project combines three types of 3D rendering techniques and systems to make its own 3D engine:

• 2D tile raycasting
  • A 3D method to get perfectly aligned 2D tiles that look 3D and rotate around the Y-axis. Works best for maze games, and older game ports. Super fast and easy to texture, however, no moving object on the X and Z-axis
• 2D line segment raycasting
  • An algorithm for rendering 2D polygons that look 3D, enabling you to render 2D and even 3D looking slopes. Really easy to texture, memory efficient, can have moving polygons on all axis
• Mode 7
  • A technique for rendering floors and ceilings, sloped roads and terrain. It is very well known for being super fast and easily textured. It can be flawlessly used with any type of raycasting, without a significant performance drop

Development

Glue3D was first shown off on August 22, 2025 on the YouTube video posted on GL00Bs YouTube channel named "Glue3d - a whole 3d game engine inside scratch ( sneak peak )" previewing off everything, the 3D rendering, Built in 3D modeler, and script editor to name a few.

Release

Released January 30, 2026 Glue3D was met with praise although backlash due to a last minute decision to obfuscate the code this would lead to people trying to deobfuscate the code to allow modding.
