SL Cert - Basic LSL Rotations

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

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
