Detailed Description

Render pass that render the scene in a cubemap and project these six renderings to a single quad.

There are currently two different projections implemented (Equirectangular and Azimuthal). This pass can be used to produce images that can be visualize with specific devices that re-maps the distorted image to a panoramic view (for instance VR headsets, domes, panoramic screens)

Note that it is often necessary to disable frustum cullers in order to render properly objects that are behind the camera.

virtual unsigned int vtkPanoramicProjectionPass::GetCubeResolution ( )

Default is 300.

virtual int vtkPanoramicProjectionPass::GetProjectionType ( )
virtual

Get/Set the type of projection.

Equirectangular projection maps meridians to vertical straight lines and circles of latitude to horizontal straight lines. Azimuthal equidistant projection maps all points of the scene based on their distance to the view direction. This projection produces a fisheye effect. Default is Equirectangular.
