Syntax

[C/C++:]
void gDefinePerspView(float xe, float ye, float ze, float dx, float dy, float dz, float dist);

[F90:]
subroutine gDefinePerspView(xe, ye, ze, dx, dy, dz, dist)
real, intent(in) :: xe,ye,ze,dx,dy,dz,dist

Arguments

xe,ye,ze
Eye position in space coordinates

dx,dy,dz
Direction of viewing

dist
Perspective distance

Description

The routine gDefinePerspView() defines a perspective view from the eye position (xe,ye,ze) along the line specified by the direction vector (dx,dy,dz). The view plane (defined to be normal to this line) and the view centre are at a distance dist from the eye position. If the perspective distance dist or all of dx, dy and dz are zero, an error message is output and no further action is taken.
