Visualization in MeVisLab

Introduction

Images and data objects can be rendered in 2D and 3D and interacted with in several ways using a set of tools available through MeVisLab. In this chapter in particular, we will focus on simple image interaction with two- and three-dimensional visualizations.

View2D and View3D

An easy way to display data and images in 2D and 3D is by using the Modules View2D and View3D. What can be done with these viewers?

View2D

1. Scroll through the slices using the mouse wheel and/or middle mouse button .

2. Change the contrast of the image by clicking the right mouse button and move the mouse

3. Zoom in and out by pressing CTRL and middle mouse button

4. Toggle between multiple timepoints (if available) via ← ArrowLeft and → ArrowRight

5. More features can be found on the help page.

View3D

1. Zoom in and out using the mouse wheel

2. Drag the 3D objects using the middle mouse button

3. Change the contrast of the image by clicking the right mouse button and moving the mouse

4. Rotate the object by pressing the left mouse button and moving the object around. The present orientation is displayed by a cube in the bottom right corner.
