Detailed Description

Camera object to manage a scene and connect to a viewport.

Class which supports OpenGL camera capabilities. Contains parameters to control various settings Also registers keys for camera motion control.

Should define a set of activities which camera can perform. These activities can then be mapped to events. ddgVector of events is then mapped to activities to allow alternate key mappings.

Member Function Documentation

bool ddgCamera::map (ddgVector3 vin, ddgVector3 * vout)

Map a 3D world coordinate to view space.

vin is in world space, vout is in view space, Returns false if point is not on view and vout is left unchanged. (Uses OpenGL)

bool ddgCamera::unmap (ddgVector3 vin, ddgVector3 * vout)

Map a view coordinate to world space.

vin is in view space, vout is in world space, Returns false if point is not in view and vout is left unchanged. (Uses OpenGL)
