rt_camera_setup()

void rt_camera_setup	(	SceneHandle	,
		flt	zoom,
		flt	aspect,
		int	alias,
		int	maxdepth,
		apivector	ctr,
		apivector	viewdir,
		apivector	updir
	)

Define a camera for a perspective projection, given the specified zoom factor, aspect ratio, antialiasing sample count, maximum ray recursion depth, and camera center, view direction, and up direction, in a left-handed coordinate system.

rt_define_image()

void rt_define_image	(	const char *	name,
		int	xsize,
		int	ysize,
		int	zsize,
		unsigned char *	rgb24data
	)

Defines a named 1-D, 2-D, or 3-D texture image with a 24-bit RGB image buffer, without any file references.

This allows an application to send Tachyon images for texture mapping without having to touch the filesystem.
