3D control

Using example from 3DreamEngine

Viewport

• W, A, S, D: up, left, down, right
• Q, E: rotate left/right
• page up: up
• page down: down
• mouse + button-1: rotate

Paddle

• up, down: move Z dir
• left, right: move X dir
• home, end: move Y dir

Notes

ODE

Geometry

• These functions set and get the body associated with a placeable geom. Setting a body on a geom automatically combines the position vector and rotation matrix of the body and geom, so that setting the position or orientation of one will set the value for both objects.
• Setting a body ID of zero gives the geom its own position and rotation, independent from any body. If the geom was previously connected to a body then its new independent position/rotation is set to the current position/rotation of the body.
