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.

void QSet_Camera_Position	(	const char *	segment,
		double	x,
		double	y,
		double	z
	)

Similar to Set_Camera_Position(), but operates on a given segment rather than the currently open one.

Parameters:

	segment	- Name of the segment(s) to be changed. Often "?Picture".
	x	- The position, in object-space coordinates, at which to locate your vantage point.
	y	-
	z	-
