This is an initial take on a set of guidelines for scripting position and rotations. It still needs a lot of work and a good deal of thought.
Basic Requirements
Basic definition of position
Absolute position
Relative position
Basic definition of a rotation
- Euler
- Axis and angle
- Quarternions
Changing position and rotation via the edit window
Intermediate Requirements
Reference Frames
- Global
- Local
Basic commands to get position information
- llGetPos
- llGetLocalPos
- llGetRootPosition
Basic commands to get rotation information
- llGetRot
- llGetLocalRot
- llGetRootRotation
Basic commands for changing position
- llSetPos
- llSetPrimitiveParams
- llSetPos within different reference frames.
Basic commands for changing rotation
- llSetRot
- llSetLocalRot
- llSetPrimitiveParams
- How the commands work in different reference frames.
- Rotations
- Multiplication and division of rotations
- Difference between left and right multiplication
Advanced Requirements
Rotations and position
- using llSetPrimitiveParams to move and rotate at the same time
- Rotating and moving a prim to a specified orientation
- Absolute coordinates
- Relative coordinates (in a link set)
Smooth movements in absolute coordinates
- Rotate and movement around the edge of a prim
- Rotate and move around a fixed point
- Rotate and move around a predefined axis
Smooth movements in local coordinates
- Rotate and movement around the edge of a prim
- Rotate and move around a fixed point
- Rotate and move around a predefined axis
Transitions =
- Smooth movements between two different orientations
