Detailed Description

template<class T>
struct EBGeometry::Render::RenderDetail::CameraView< T >

What every pixel needs from the camera, worked out once per frame: the eye, the view's axes and the field of view's slope.

Internal helper; not part of the public API. It depends on the camera alone, so it is computed on the host even for a device render (the shape's box, which only a device view may read there, is not in it).

Template Parameters

T	Floating-point precision.

The documentation for this struct was generated from the following file:
