Create a clone of this camera.
Implements iCamera. Definition at line 342 of file csengine/camera.h. References csCamera::csCamera. |
|
Eliminate roundoff error by snapping the camera orientation to a grid of density n.
Implements iCamera. Definition at line 388 of file csengine/camera.h. |
|
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. Implements iCamera. Definition at line 408 of file csengine/camera.h. |
|
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. Implements iCamera. Definition at line 400 of file csengine/camera.h. |
|
Return the FOV (field of view) in pixels.
Implements iCamera. Definition at line 345 of file csengine/camera.h. |
|
Return the FOV (field of view) in degrees.
Implements iCamera. Definition at line 349 of file csengine/camera.h. |
|
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. Implements iCamera. Definition at line 384 of file csengine/camera.h. |
|
Return the inverse flield of view (1/FOV) in pixels.
Implements iCamera. Definition at line 347 of file csengine/camera.h. |
|
Get the hit-only-portals flag.
Implements iCamera. Definition at line 425 of file csengine/camera.h. |
|
Get the current sector.
Implements iCamera. Definition at line 381 of file csengine/camera.h. |
|
Set the X shift amount. The parameter specified the desired X coordinate on screen of the projection center of the camera. Implements iCamera. Definition at line 356 of file csengine/camera.h. |
|
Set the Y shift amount. The parameter specified the desired Y coordinate on screen of the projection center of the camera. Implements iCamera. Definition at line 358 of file csengine/camera.h. |
|
'const' version of GetTransform ().
Implements iCamera. Definition at line 365 of file csengine/camera.h. |
|
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. Implements iCamera. Definition at line 363 of file csengine/camera.h. |
|
Calculate inverse perspective corrected point for this camera.
Implements iCamera. Definition at line 416 of file csengine/camera.h. |
|
Return true if space is mirrored.
Implements iCamera. Definition at line 392 of file csengine/camera.h. |
|
Moves the camera a relative amount in camera coordinates.
Implements iCamera. Definition at line 374 of file csengine/camera.h. |
|
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. Implements iCamera. Definition at line 378 of file csengine/camera.h. |
|
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). Implements iCamera. Definition at line 372 of file csengine/camera.h. |

|
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. Implements iCamera. Definition at line 421 of file csengine/camera.h. |
|
Calculate perspective corrected point for this camera.
Implements iCamera. Definition at line 412 of file csengine/camera.h. |
|
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). Implements iCamera. Definition at line 404 of file csengine/camera.h. |
|
Set the FOV in pixels. 'fov' is the desired FOV in pixels. 'width' is the display width, also in pixels. Implements iCamera. Definition at line 351 of file csengine/camera.h. |
|
Set the FOV in radians. 'fov' is the desired FOV in degrees. 'width' is the display width in pixels. Implements iCamera. Definition at line 353 of file csengine/camera.h. |
|
Set mirrored state.
Implements iCamera. Definition at line 396 of file csengine/camera.h. |
|
Set the shift amount. The parameter specified the desired projection center of the camera on screen. Implements iCamera. Definition at line 360 of file csengine/camera.h. |
|
Move to another sector.
Implements iCamera. Definition at line 382 of file csengine/camera.h. |
|
Set the transform corresponding to this camera. In this transform, 'other' is world space and 'this' is camera space. Implements iCamera. Definition at line 367 of file csengine/camera.h. |
