NAME

SG_Point — Agar-SG point node

SYNOPSIS

#include <agar/core.h>
#include <agar/sg.h>

DESCRIPTION

The SG_Point node represents a reference point in space. This is useful in feature-based modeling, or as construction geometry.

INHERITANCE HIERARCHY

AG_Object(3) -> SG_Node(3) -> SG_Geom(3) -> SG_Point.

INITIALIZATION

SG_Point *
SG_PointNew(SG_Node *parent, const char *name, const M_Vector3 *p);

void
SG_PointSize(SG_Node *parent, M_Real size);

void
SG_PointColor(SG_Node *parent, M_Color color);

The SG_PointNew() function creates a new point at the origin of the parent node. If the p argument is non-NULL, the point is translated to the specified coordinates.

The functions SG_PointSize() and SG_PointColor() specify a point size in pixels, and a color, respectively, which will be used in graphically rendering the point node.

STRUCTURE DATA

For the SG_Point object:

float size

Size factor used in graphically rendering the point.

M_Color color

Color used in graphically rendering the point.

HISTORY

The SG_Point node class first appeared in Agar 1.6.0.
