static class Lines
A line drawing class! This is an easy way to visualize lines or relationships between objects. The current implementation uses a quad strip that always faces the user, via vertex shader manipulation.
Static Methods
| Add | Adds a line to the environment for the current frame. |
| AddAxis | Displays an RGB/XYZ axis widget at the pose! Each line is extended along the positive direction of each axis, so the red line is +X, green is +Y, and blue is +Z. A white line is drawn along -Z to indicate the Forward vector of the pose (-Z is forward in StereoKit). |
Examples
Identity Pose
The identity pose is a Pose at (0,0,0) facing Forward, which in
StereoKit is a direction of (0,0,-1) represented by a Quaternion of
(0,0,0,1). Note that a Quaternion of (0,0,0,0) is invalid, and can
cause problems with math, so using default or an empty
new Pose() with this struct can result in bad math results.
Pose.Identity is a good default to get used to!
Note that Lines.AddAxis here shows the Pose orientation by
drawing the pose local X+ (red) Y+ (blue) Z+ (green) axis lines in
the positive direction, and Forward in white.
Pose pose = Pose.Identity;
Lines.AddAxis(pose);
// Show the origin for clarity
Lines.Add(V.XYZ(-1,0,0), V.XYZ(1,0,0), new Color32(100,0,0,100), 0.0005f);
Lines.Add(V.XYZ(0,-1,0), V.XYZ(0,1,0), new Color32(0,100,0,100), 0.0005f);
Lines.Add(V.XYZ(0,0,-1), V.XYZ(0,0,1), new Color32(0,0,100,100), 0.0005f);
