Vector Visualizer is a geometry and shader node-based tool designed to help users understand vector math and rotations directly within the 3D viewport. It allows you to create, modify, normalize, and combine vectors while viewing the changes in real time. The tool represents vectors as dynamically colored arrows based on their directional XYZ components and provides readouts for vector data. The included Pro features provide advanced visualization capabilities, such as a multi-vector math calculator for operations like cross products and reflections, a Gimbal visualizer to observe Euler rotation inheritance, and a dedicated setup to observe the behavior of the Align Rotation to Vector geometry node. Additional viewport aids include local axis visualization, axis-by-axis breakdowns, ghost vectors, and customizable grids.
