Lines(const mat4d &transform, const vec4f &rgba)

Constructor to initialize a set of lines.

Parameters:

  • transform[in] – 4x4 matrix representing a transform for the points

  • rgba[in] – 4x1 float matrix representing lines color in RGBA format

void update_from(const Lines &other)

void set_points(size_t num_points, const float *points)

Set the 3D points defining the lines.

Each line is defined by 2 points, a start and an end.

Parameters:

  • num_points[in] – number of points

  • points[in] – num_points*3 array of doubles representing the xyz of each point

void set_transform(const mat4d &pose)

Set the transform for the lines.

Parameters:

pose[in] – new pose for the lines
