Function Documentation

void g2o::drawArrow	(	float	length = 1.0f,
		float	radius = -1.0f,
		int	nbSubdivisions = 12
	)

Draws a 3D arrow along the positive Z axis.

Definition at line 58 of file primitives.cpp.

void g2o::drawArrow2D	(	float	len,
		float	head_width,
		float	head_len
	)

draw a 2D arrow along the x axis with the given len

Definition at line 68 of file primitives.cpp.

void g2o::drawAxis

(

float

length = 1.f

)

Draws an XYZ axis, with a given len (default is 1.0).

The axis position and orientation matches the current modelView matrix state: three arrows (red, green and blue) of length length are drawn along the positive X, Y and Z directions.

Definition at line 53 of file primitives.cpp.

void g2o::drawBox	(	GLfloat	l,
		GLfloat	w,
		GLfloat	h
	)

draw a box that is centered in the current coordinate frame

Parameters:

l	length of the box (x dimension)
w	width of the box (y dimension)
h	height of the box (z dimension)

Definition at line 117 of file primitives.cpp.

void g2o::drawCone	(	GLfloat	radius,
		GLfloat	height
	)

draw a cone

Definition at line 195 of file primitives.cpp.

void g2o::drawCylinder	(	GLfloat	radius,
		GLfloat	height
	)

draw a (closed) cylinder

Parameters:

radius	the radius of the cylinder
height	the height of the cylinder

Definition at line 205 of file primitives.cpp.

void g2o::drawDisk

(

GLfloat

radius

)

draw a disk

Definition at line 218 of file primitives.cpp.

void g2o::drawEllipsoid	(	GLfloat	r1,
		GLfloat	r2,
		GLfloat	r3
	)

draw a ellipsoid whose center is in the origin of the current coordinate frame

Parameters:

r1	radius along x axis
r2	radius along y axis
r3	radius along z axis

Definition at line 182 of file primitives.cpp.

void g2o::drawGrid	(	float	size = 1.0f,
		int	nbSubdivisions = 10
	)

Draws a grid in the XY plane, centered on (0,0,0) (defined in the current coordinate system).

Definition at line 63 of file primitives.cpp.

void g2o::drawPlane	(	GLfloat	l,
		GLfloat	w
	)

draw a plane in x-y dimension with a height of zero

Parameters:

l	length in x
w	width in y

Definition at line 163 of file primitives.cpp.

void g2o::drawPoseBox

(

draws a box used to represent a 6d pose

Definition at line 83 of file primitives.cpp.

void g2o::drawPyramid	(	GLfloat	length,
		GLfloat	height
	)

draw a pyramid

Definition at line 224 of file primitives.cpp.

void g2o::drawRangeRing	(	GLfloat	range,
		GLfloat	fov,
		GLfloat	range_width = 0.05
	)

draw a range ring

Parameters:

range	the range (radius) of the partial ring
fov	Field Of View of the range sensor
range_width	specify how thick the ring should be drawn

void g2o::drawSlice	(	GLfloat	radius,
		GLfloat	height,
		GLfloat	fov,
		int	slices_per_circle = 32
	)

draw a slice of a cylinder (approximated with slices_per_circle triangles for the complete circle)

Parameters:

radius	the radius of the cylinder
height	the height of the cylinder
fov	the "fov" of the slice (om degree)
slices_per_circle	the number of triangle used to approximate the fulle circle

Definition at line 242 of file primitives.cpp.

void g2o::drawSphere
