Step 1: Establish the Base Object and Coordinate Frames

The first step is to create a simple 3D object in the VR environment and clearly define its global and local coordinate frames. The global coordinate system represents the fixed world reference, while the local coordinate system is attached to the object itself. Both coordinate axes are visualized using color-coded X, Y, and Z directions.

This step is essential because all geometric transformations—translation, rotation, and scaling—are applied relative to these coordinate frames. Without explicitly defining and visualizing them, users cannot understand what reference frame a transformation is acting in. Establishing this baseline ensures that every transformation applied later has a clear mathematical and spatial meaning.
