This article is for customers of Courseware and Web Suite who are experiencing issues manipulating the 3D models from internet browsers on laptops and desktops. Here are solutions for issues including slow or laggy moving models, or the app crashing or freezing.
Launch issues
Launching Visible Body via a web browser is not as fast as expected. What can I do?
The first time you launch the application, your browser will automatically download our highly detailed anatomical models. This download can take several minutes to complete, depending on the speed of your internet connection.
The newest version of Human Anatomy Atlas 2022 + is significantly faster than the other web applications. Use Atlas 2022 + on Chrome for the fastest load times. If you are using an older version of Human Anatomy Atlas—or any version of Muscle Premium or Anatomy & Physiology— follow the steps below.
First, confirm your computer meets the minimum system requirements.
You can find the system requirements for the web versions of our apps here:
- Human Anatomy Atlas
- Courseware
- Web Suite
- Physiology & Pathology
- Muscle Premium
- Anatomy & Physiology
- Physiology Animations
Second, confirm you have a reliable high-speed internet connection.
Broadband Cable, DSL, or other wired connections: There are many websites from internet providers and third parties available to test internet speeds. A few popular ones are listed below.
- http://www.speedtest.net
- http://www.cnet.com/internet-speed-test/
- https://testmy.net/
- https://fast.com/
Wi-Fi: Network and signal strengths can be extremely variable depending on hardware configuration, interference, number of devices connected to the network, and activity. Reboot your modem and router and turn off other devices to ensure optimal performance.
A wired connection is best.
Third, check your browser extensions.
Certain browser extensions may prevent Visible Body's apps from successfully launching. Try turning off your browser extensions and then launch the app again.
Trouble moving the 3D models.
If you have poor control of the 3D model when using a trackpad, try using the virtual joystick, or a keyboard and mouse.
Using the virtual joystick:
First, open the settings menu, and under controls, turn on the joystick option.
- The center of the virtual joystick is for controlling the rotation of the model. Click and drag on the center dot to spin.
- The arrows around the virtual joystick will pan the model around the screen.
- The slider below the virtual joystick is for controlling the zoom level of the view.
Using a keyboard and mouse:
- Left-click on the model to rotate.
- Hold down the spacebar or right-click and drag the mouse to pan or drag the model across the screen.
- Scroll up and down on the mouse to zoom in and out.
- Double-click on the model to automatically zoom into and center the object on the screen.

The app is freezing or crashing.
Clearing your cache can help free up memory to speed up your internet searches and prevent web applications from crashing.
Windows:
Chrome and Edge:
- With your selected browser open, press the keys [Ctrl], [Shift] and [del] on your Keyboard.
- Select the time range "All time”, to empty the whole browser cache.
- Check the Option "Cached images and files".
- Confirm your settings, and select the blue "Clear data" or "Clear now" button.
- Refresh the page.
Mac:

Performance issues
Performance while running Visible Body via a web browser is not as fast as expected. What can I do?
First, confirm your computer meets the minimum system requirements.
You can find the system requirements for the web versions of our apps here:
- Human Anatomy Atlas
- Physiology & Pathology
- Muscle Premium
- Anatomy & Physiology
- Courseware
- Web Suite
- Physiology Animations
Second, exit other applications and close browser tabs
Visible Body apps are resource-intensive. To get the best possible performance, please exit/quit other applications/programs before you launch and close additional windows and tabs in your browser.
Third, try hiding structures you don’t need.
You can also try hiding body systems and objects that you don’t need to view—performance improves with fewer visible objects in the viewing area.
Fourth, try clearing your cache and cookies.
Often times, your cache may be full or still have old data in it, or cookies could be hogging your system's resources. By clearing your cache and cookies, your browser will gather only the latest version of the web apps. This will also minimize the chances of having corrupted or incomplete data.
Lastly, try checking the speed of your internet connection.
Checking the speed of your internet connection, your upload and download speeds, is simple. There are a number of speed test websites online you can use. Many users prefer Google's built-in speed test.
In the URL bar, search for "Internet speed test."
Clicking on the blue Run Speed Test button will open a pop-up which will test your upload and download speeds and let you know how your connection measures up.
Structures appear to flicker when moving the camera
M1 Macs have an issue that makes certain structures flicker in some of our models. This issue also exists in some VBio models and also in the Atlas muscle actions. Here's the fix for that problem:
-
Go to chrome://flags
-
Search for “Choose ANGLE graphics backend”
-
Choose “Metal” as the option
-
Restart the browser (the option to restart should appear in the bottom right corner after changing the setting).
If these steps don't work for you, or you encounter other image issues, please email helpdesk@visiblebody.com.
