Constructor & Destructor Documentation

PinholeCamera::PinholeCamera (  const sheep::Matrix4 &  m, sheep::Real  hfov, sheep::Real  aspect_ratio )

'm' is the object space to world space transformation matrix. 'hfov' is the horizontal field of view, expressed in radians. Definition at line 33 of file pinholecamera.cpp.

Member Function Documentation

Ray PinholeCamera::ComputeRay (  const Context &  context, const sheep::Point2 &  p )  const [virtual]

Returns a ray whose origin is at camera location, and which is directed toward the point 'p'. 'p' is a point on the film plane. It is expressed in NDC. The returned ray is expressed in world space. The direction of the returned ray IS unit-length. Implements toxic::ICamera. Definition at line 38 of file pinholecamera.cpp. References sheep::Point2::m_x, sheep::Point2::m_y, and sheep::Vector3::Normalize().

Point2 PinholeCamera::Project (  const sheep::Point3 &  p  )  const [virtual]

Projects a point in the scene to the image plane. Implements toxic::ICamera. Definition at line 57 of file pinholecamera.cpp.
