Set_Camera_Position

Functions

void Set_Camera_Position (double x, double y, double z)
void DSet_Camera_Position (double x, double y, double z)

Function Documentation

void Set_Camera_Position ( double  x,
double  y,
double  z 
)

Sets up your viewing tripod within the framework of the scene you've created.

Parameters:
x- The position, in object-space coordinates, at which to locate your vantage point.
y-
z-

DETAILS

In order to look at the scene you've created, you need some way of telling the system where to locate and aim its "TV camera". Set_Camera_By_Volume() is a simple utility that makes some assumptions and lets you quickly set up a 2-D camera. At the other extreme, the generic Set_Camera() routine requires complete details about every aspect of arranging the camera. In between these extremes are a set of routines (see below) that let you vary one detail at a time. In particular, Set_Camera_Position() lets you say where in your scene the camera is to stand, and Set_Camera_Target() lets you say what it's pointing at.

NOTES

If no camera exists in the specified segment, then a complete default camera will be provided, without regard to any camera specifications that there may be in the higher-up segments.

If, at Update time, the camera ends up positioned right on top of the camera target, an error is reported.

RESTRICTIONS

void DSet_Camera_Position ( double  x,
double  y,
