Syntax

[C/C++:]
void gSetViewEyeDistance(float dist);

[F90:]
subroutine gSetViewEyeDistance(dist)
real, intent(in) :: dist

Arguments

dist
Perspective distance

= 0.0,

Switch to parallel view

Description

The routine gSetViewEyeDistance() calculates a new eye position, keeping the view plane fixed, so that the perspective distance is equal to dist.

If dist<0.0, the new eye position is on the opposite side of the view plane, i.e. the direction of viewing is reversed.

If dist=0.0, the view is set to a parallel view, using the current view direction and view plane.
