Cortona 3D Viewer (formerly Cortona VRML Client)

Although 3D content can be viewed online, not all types of data are supported by the web browsers and many times a special plug-in is required to carry out the task.

Cortona 3D Viewer is such an add-on. Designed to work with the major browsers on the market (Internet Explorer, Google Chrome, Mozilla Firefox, Opera and Safari), it is available for both 32-bit and 64-bit computers.

Installing the plug-in goes fast but users need to pay attention to the process in order to select the renderer (DirectX or OpenGL) that should be used in Cortona 3D Viewer and the desired web browser that should open the VRML data.

VRML (virtual reality modeling language) files are specifically created for representing 3D vectorial graphics that can be used with a web browser.

When the 3D image is loaded Cortona kicks in and renders the graphics. The navigation options available at the bottom of the screen permit viewing the object from any side. You can control the navigation speed.

Among the configuration options of the plug-in there is the possibility to change the background color, define a gradient setting, control the CPU load in order to enable a higher or lower frame rate during the navigation.

There is the possibility to change the renderer and set it up to meet your system’s capabilities. Changes can affect the textures and their sizes.

Cortona 3D Viewer is not complicated to handle and for most users the default configuration is also the best. Once installed it makes sure that 3D models can be loaded and viewed with the web browser, which is its exact purpose. On the other hand, navigation can be improved.
