yAxis

Syntax

    member(whichCastmember).transform.yAxis

Description

3D transform property; allows you to get but not set the vector representing the transform's canonical Y axis in transform space.

Example

The first line of this example sets the transform of the model ModCylinder to the identity transform. The next two lines show that the Y axis of ModCylinder is the vector ( 0.0000, 1.0000, 0.0000). This means that the Y axis of ModCylinder is aligned with the Y axis of the world. The next line rotates ModCylinder 90° around its X axis. This rotates the axes of ModCylinder as well. The last two lines show that the Y axis of ModCylinder is now the vector ( 0.0000, 0.0000, 1.0000 ). This means that the Y axis of ModCylinder now is aligned with the positive Z axis of the world.

    member("Engine").model("ModCylinder").transform.identity()
    put member("Engine").model("ModCylinder").transform.yAxis
    -- vector( 0.0000, 1.0000, 0.0000 )
    member("Engine").model("ModCylinder").rotate(90, 0, 0)
    put member("Engine").model("ModCylinder").transform.yAxis
    -- vector( 0.0000, 0.0000, 1.0000 )
