inlineprivate

Member Function Documentation

Position VolViz::Private_::CameraClient::project ( Position const &  position, Length  ambientScale  ) const

inlineprivatenoexcept

Projects a 3D point in world coordinates into the screen coordinate system

Parameters

position	position in 3D world space
ambientScale	the physical length of one unit in the target 3D

Returns

projected position including depth

Matrix4 VolViz::Private_::CameraClient::projectionMatrix ( ) const

inlineprivatenoexcept

Returns the camera's projection matrix.

Position VolViz::Private_::CameraClient::unproject ( Position2 const &  screenPos, float  depth, Length  ambientScale  ) const

inlineprivatenoexcept

Unprojectis a point in screen coordinates with known depth into the 3D scene

Parameters

screenPos	the source point in screen coordinate system, i.e. (-1, -1) is the bottom left, (1, 1) is the top right
depth	the depth of the pixel at screenPos
ambientScale	the physical length of one unit in the target 3D space

Matrix4 VolViz::Private_::CameraClient::viewMatrix ( Length  ambientScale ) const

inlineprivatenoexcept

Returns the camera's view matrix, i.e. the inverse camera transform.

Matrix4 VolViz::Private_::CameraClient::viewProjectionMatrix ( Length  ambientScale ) const

inlineprivatenoexcept

Returns the product of projectionMatrix() * viewMatrix(...)
