I don't know the calling consttants though... did they not give you a help file with this? It is a part of the download when I bought the lib???Camera Range
Camera range determines how far into the distance a camera can 'see'. You specify 2 values for camera range - a near value and a far value. All rendering is clipped to this range.
Its a good idea to try and keep the near value as high as possible, while keeping the far value as low as possible. This helps to minimize z-buffer problems like 'jaggies'. By default, the near value for a new camera is 1, and the far value is 1000.
To change the camera range, use the CameraRange command:
;Sets the near range to 5 and the far range to 5000
CameraRange camera,5,5000
Camera Zoom
Changing a cameras zoom allows you to 'zoom-in' or 'zoom-out' of the action in the world. The default zoom value for a new camera is 1. Zoom values greater than 1 will cause a 'zoom-in' effect, while zoom values less than 1 will cause a 'zoom-out'. Zoom values should never be set at 0 or less!
The CameraZoom command controls camera zoom:
;Zoom-in a bit!
CameraZoom camera,1.5
erm... i'm using the blitz3d SDK -- not all blitz3d functions are available. and the 2 functions above have nothing to do with the focal length of the camera (or field of view). i think the function is 'SetCameraFOV' or something.Rook Zimbabwe wrote:Let me look at my Blitz3D docs...

Code: Select all
Function HUD_Camera_FOV_Correction(ThisCamera)
Scale640x480# = 480.0 / 640.0
ScaleThisRes# = Float(GraphicsHeight()) / Float(GraphicsWidth())
Rescale# = Scale640x480# / ScaleThisRes#
ScaleEntity ThisCamera, 1, Rescale#, 1, True
End Function
. took me a while to notice the difference though lol.
