|o||The projection matrix, and in particular, the near and far clip planes, are not altered. Thus, trying to move in too close or out too far could cause objects to be clipped away.|
o Various fancy rendering techniques involve rendering a quad that is carefully aligned to the screen; altering the camera will break such techniques. There is ultimately no general fix as it is impossible to know when an application is dealing with the real world. If you are writing such an application and wish it to work with this filter-set, you should use a vertex program that ignores the model-view matrix in situations where you do not want this filter-set to interfere.
o Applications that rely on the feedback buffer are likely to break.
mouse_dgaThis is a boolean option which should be enabled when debugging an application that uses XDGA(3) to get relative motion data from the mouse. If the camera goes all over the place as soon as you move the mouse, try enabling this option (SDL-based applications are the main culprits).
speedThis sets the speed at which the camera moves. Since each application has a different scale, you will need to adjust the value for each application (but dynamic control is also possible; see below).
key_forward, key_back, key_left, key_rightThese are the keys for moving the camera. They default to the arrow keys.
key_faster, key_slowerThese keys control the speed of the camera, doubling or halving it respectively. They default to PageUp and PageDown.
key_resetThis key cancels any alterations made, restoring the camera to where the application thinks it is. There is no default.
key_toggleThis key alternately releases and recaptures the mouse. It can be useful if you need to use the mouse in another window without completely disabling the filter-set (which would also restore the camera position). There is no default.
This toggles display of the original view frustum. If this driver supports GL_NV_depth_clamp, depth clamping is used to prevent the frustum from being clipped to the near and far clip planes. There is no default.
