Cortona3D Viewer is a Windows software for installing a plugin into Google Chrome, Mozilla Firefox, Internet Explorer, Microsoft Edge and other common web browsers. It provides instruments for viewing and interacting with VRML 3D worlds. There is full support for Adobe Flash.

Setup

During the installation process you are prompted to select the correct rendering engine from two options: DirectX or OpenGL. The choice depends on graphics card parameters and overall system performance. It is easy to change the engine later in the Settings menu. The rest of the setup is automatic.

How it works

Users can open the included sample scene to learn how to navigate through the 3D environment. There are instruments for rolling, turning and panning. It is possible to move the virtual camera to a specific point in the scene and straighten the view. The animation speed is adjustable as well.

Settings

The Preferences menu lets you configure the background color and toggle the FPS counter. Moreover, a slider for tuning the maximum CPU load is provided. This functionality is helpful for improving performance on older computers.
