Vectors... they're incredibly useful in so many ways, but can be difficult to understand without visualizing what is actually happening. If you use vectors for your Blender project, but find them unintuitive and confusing, then Vector Visualizer is for you!

Vector Visualizer is a simple interactive Blender tool that lets you play with vectors and see changes in real time. A basic understanding of Blender is recommended for navigating the 3D view and some simple menus.

Create a vector, change it, normalize it, rotate it or put two vectors together and generate a third vector based on a variety of math input options.

*Note that currently, only XYZ Euler rotations are supported.

Vector Visualizer is built entirely with geometry and shader nodes. You'll need version 4.1.1 or later.

Vector Visualizer 1.1 Update

This update adds a new tool specifically designed to show how the "Align Rotation to Vector" (Previously the "Align Euler to Vector") geometry node in Blender works. The node calculates and outputs an Euler rotation between a given vector and the X,Y or Z axis, which is very useful for all sorts of applications. This update allows you to visualize these rotations more easily.

There are two input modes, you can either input a vector of your own or just drag the selector around to point a vector wherever you'd like.

The rotation can even be animated to show each rotation, in order:

This update is for the pro version only. Note that it comes as a separate file from the original Vector Visualizer.

Included Visualization Tools:

Vector Arrow

-See a vector represented as an arrow.

-The arrow will change color based on the direction it is pointed (corresponding to the RGB value).

Vector Info

- See text information about your current vector.

Local Axis Relative to Global Axis

-View the vector's local axis to keep track of orientation while rotating.

Axis-by-Axis View

-See the vector broken down into each individual axis.

Gimbal (PRO Feature)

-Visualize Euler rotation and see how axes inherit rotation based on their order.

-See how much rotation has occurred on each gimbal axis.

Multi-Vector Math (PRO Feature)

-Calculate a third vector based on two input vectors.

Supported operations:

• Add
• Subtract
• Multiply
• Divide
• Cross Product
• Project
• Reflect

Align Euler to Vector (PRO Feature)

-Visualize the Align Euler to Vector node*

*Note that due to limitations, the dynamic color does not adjust based on the align Euler to vector.

Plus!

-Ghost vectors (see the vector before rotation).

-Material transparency settings.

-Change the relative origin of the vector.

-Enhanced grid that will show in renders with optional XZ and YZ grids (shows XY by default).

-Show grid as dots or lines.

Patch notes: Version 1.01: Fixed an issue where the text orientation of the X and Y axis on the gimbal were backwards. This made it incorrectly look like the rotation direction was reversed (positive rotation went clockwise instead of the correct counterclockwise).
