Using different views in OpenGL

You can get different points of view of your scene. It can be useful if you want to watch something for example. In order to get those viewports, you have to add :

<OglViewport screenPosition="0 0" screenSize="250 250" cameraPosition="-1 2.7 5" cameraOrientation="-0 -0 -0 1" />

where :

• screenPosition = : position on the viewer
• screenSize = : size of the viewport
• cameraPosition = : position of the camera in eye’s space
• cameraOrientation = : camera’s orientation (direction and up vectors)

cameraPosition and cameraOrientation can be easily retrieved, using viewer’s view file: get the view you want to add with the main viewer, save the view, open the resulting yourscene.scn.view file and copy-paste the 2 vectors into the corresponding fields.

Example

• example/Component/visualmodel/OglViewport.scn
