This class represents camera objects which can be used to render a world in the engine. A camera has the following properties:
Definition at line 77 of file iengine/camera.h.
|
Create a clone of this camera.
Implemented in csCamera::Camera. |
|
Eliminate roundoff error by snapping the camera orientation to a grid of density n.
Implemented in csCamera::Camera. |
|
Get the camera number. This number is changed for every new camera instance and it is also updated whenever the camera transformation changes. This number can be used to cache camera vertex arrays, for example. Implemented in csCamera::Camera. |
|
Get the 3D far plane that should be used to clip all geometry. If this function returns 0 no far clipping is required. Otherwise it must be used to clip the object before drawing. Implemented in csCamera::Camera. |
|
Return the FOV (field of view) in pixels.
Implemented in csCamera::Camera. |
|
Return the FOV (field of view) in degrees.
Implemented in csCamera::Camera. |
|
Check if there is a polygon in front of us in the direction defined by 'v' (world space coordinates). Return the nearest polygon. Note that this function will not check beyond 'v'. So only the vector between the current position of the camera and 'v' is checked. Implemented in csCamera::Camera. |
|
Return the inverse flield of view (1/FOV) in pixels.
Implemented in csCamera::Camera. |
|
Get the hit-only-portals flag.
Implemented in csCamera::Camera. |
|
Get the current sector.
Implemented in csCamera::Camera. |
|
Set the X shift amount. The parameter specified the desired X coordinate on screen of the projection center of the camera. Implemented in csCamera::Camera. |
|
Set the Y shift amount. The parameter specified the desired Y coordinate on screen of the projection center of the camera. Implemented in csCamera::Camera. |
|
'const' version of GetTransform ().
Implemented in csCamera::Camera. |
|
Get the transform corresponding to this camera. In this transform, 'other' is world space and 'this' is camera space. WARNING! It is illegal to directly assign to the given transform in order to modify it. To change the entire transform you have to use SetTransform(). Note that it is legal to modify the returned transform otherwise. Just do not assign to it. Implemented in csCamera::Camera. |
|
Calculate inverse perspective corrected point for this camera.
Implemented in csCamera::Camera. |
|
Return true if space is mirrored.
Implemented in csCamera::Camera. |
|
Moves the camera a relative amount in camera coordinates.
Implemented in csCamera::Camera. |
|
Moves the camera a relative amount in camera coordinates, ignoring portals and walls. This is used by the wireframe class. In general this is useful by any camera model that doesn't want to restrict its movement by portals and sector boundaries. Implemented in csCamera::Camera. |
|
Moves the camera a relative amount in world coordinates. If 'cd' is true then collision detection with objects and things inside the sector is active. Otherwise you can walk through objects (but portals will still be correctly checked). Implemented in csCamera::Camera. |

|
If the hit-only-portals flag is true then only portals will be checked with the 'MoveWorld()' function. This is a lot faster but it does mean that you will have to do collision detection with non-portal polygons using another technique. The default for this flag is true. Implemented in csCamera::Camera. |
|
Calculate perspective corrected point for this camera.
Implemented in csCamera::Camera. |
|
Set the 3D far plane used to clip all geometry. If the pointer is 0 then far plane clipping will be disabled. Otherwise it will be enabled and the plane will be copied (so you can free or reuse the pointer you give here). Note that the far-plane will cull away geometry which is on the negative side of the plane (with csPlane3::Classify() function). Implemented in csCamera::Camera. |
|
Set the FOV in pixels. 'fov' is the desired FOV in pixels. 'width' is the display width, also in pixels. Implemented in csCamera::Camera. |
|
Set the FOV in radians. 'fov' is the desired FOV in degrees. 'width' is the display width in pixels. Implemented in csCamera::Camera. |
|
Set mirrored state.
Implemented in csCamera::Camera. |
|
Set the shift amount. The parameter specified the desired projection center of the camera on screen. Implemented in csCamera::Camera. |
|
Move to another sector.
Implemented in csCamera::Camera. |
|
Set the transform corresponding to this camera. In this transform, 'other' is world space and 'this' is camera space. Implemented in csCamera::Camera. |
