Draws x,y,z axes representing the current reference frame.

This function draws a set of x,y,z axes, which can be helpful for understanding which way is up. There are no unit markings nor arrowheads. Axes are not drawn in the negative directions. Axes are drawn in red (+x), green (+y) and blue (+z), starting from the origin.

Parameters

size	The size at which to draw the axes.

Draws grid planes representing the current reference frame.

This function draws a set of three double-ended grid planes centered at the origin. Parameters allow each of the grid planes (yz,xz, and xy) to be turned on or off. Optionally, the function can include white numeric labels for grid subdivisions. (Numeric labels are drawn using ofDrawBitmapString internally.)

The yz plane (at x=0) is drawn in red. The xz plane (at y=0) is drawn in green. The xy plane (at z=0) is drawn in blue.

Parameters

stepSize	distance between (parallel) lines on the grid
numberOfSteps	number of lines to draw on each side of the central axis of the grid. A number of 8 will draw 8 lines on each side of the central axis, plus one line at the central axis.
labels	Whether or not labels are drawn.
x	Whether or not the yz plane (at x=0) is drawn.
y	Whether or not the xz plane (at y=0) is drawn.
z	Whether or not the xy plane (at z=0) is drawn.

Draws the YZ grid plane representing the current reference frame.

This function draws the YZ grid plane, at x=0, in a double-ended manner centered at the origin. Optionally, the function can include white numeric labels for grid subdivisions. (Numeric labels are drawn using ofDrawBitmapString internally.) The grid is drawn with the current color (i.e. set with ofSetColor).

Parameters

stepSize	distance between (parallel) lines on the grid
numberOfSteps	number of lines to draw on each side of the central axis of the grid. A number of 8 will draw 8 lines on each side of the central axis, plus one line at the central axis.
labels	Whether or not labels are drawn.

Draws an arrow with the current color.

This function draws an arrow from a start (tail) point to an end (head) point, with a conical arrowhead at the end point. The arrow is drawn in the current color (e.g. set with ofSetColor).

Parameters

start	The start point (tail) of the arrow, expressed as an ofVec3f.
end	The end point (head) of the arrow, expressed as an ofVec3f.
headSize	The size of the arrowhead.

This function renders a set of 3 axis-aligned circular bands, centered at the origin.

Parameters

radius	The radius of the circular bands.
stripWidth	The width of the circular bands. The default is 10 units.
circleRes	The resolution of the circular bands. The default is 60 segments.
