TransformBuilder allows for the creation of complex transformations by combining translation and rotation operations. These operations can be chained together to create composite transformations.

It is important to note that chaining transformations makes it so that the subsequent transformations are applied as if looking from the rotation of the previous transformation, not from the world graph. For example, if you rotate 180 degrees around the y-axis, then move +1 meter along the z-axis, the resulting world position will be (0, 0, -1) instead of (0, 0, 1).

Example usage:

val pose = TransformBuilder().move(1f, 2f, 3f).then(TransformBuilder().rotateX(90f)).build()

Functions

build ()	Builds the final Transform from the configured transformation steps. Signature fun build(): Transform Returns Transform A Transform object representing the composite transformation Throws NullPointerException if no transformation steps have been added
cosDegrees ( angleInDegrees )	Helper function that calculates the cosine of an angle specified in degrees. Signature fun cosDegrees(angleInDegrees: Float): Float Parameters angleInDegrees: Float The angle in degrees Returns Float The cosine value of the angle
degreesToRadians ( angleInDegrees )	Helper function that converts an angle from degrees to radians. Signature fun degreesToRadians(angleInDegrees: Float): Float Parameters angleInDegrees: Float The angle in degrees Returns Float The equivalent angle in radians
move ( x , y , z )	Creates a translation transformation. It is important to note that the translation is applied as if looking from the rotation of the previous TransformBuilder transformation, not from the world graph. For example, if you had rotated 180 degrees around the y-axis, the applied this transformation to move with z=1, the resulting world position will be (0, 0, -1) instead of (0, 0, 1). Signature fun move(x: Float = 0.0f, y: Float = 0.0f, z: Float = 0.0f): TransformBuilder.TransformStepBuilder Parameters x: Float The translation distance along the X axis y: Float The translation distance along the Y axis z: Float The translation distance along the Z axis Returns TransformBuilder.TransformStepBuilder A TransformStepBuilder that can be used to chain additional transformations
rotate_x ( angleInDegrees )	Helper function that creates a quaternion representing a rotation around the X axis. Signature fun rotate_x(angleInDegrees: Float): Quaternion Parameters angleInDegrees: Float The rotation angle in degrees Returns Quaternion A Quaternion representing the rotation
rotate_y ( angleInDegrees )	Helper function that creates a quaternion representing a rotation around the Y axis. Signature fun rotate_y(angleInDegrees: Float): Quaternion Parameters angleInDegrees: Float The rotation angle in degrees Returns Quaternion A Quaternion representing the rotation
rotate_z ( angleInDegrees )	Helper function that creates a quaternion representing a rotation around the Z axis. Signature fun rotate_z(angleInDegrees: Float): Quaternion Parameters angleInDegrees: Float The rotation angle in degrees Returns Quaternion A Quaternion representing the rotation
rotateX ( angleInDegrees )	Creates a rotation transformation around the X axis. Note that the rotation is applied as if looking from the rotation of the previous transformation, so if you rotated 180 degrees around the x-axis, then applied this transformation to rotate 90 degrees around the x-axis, the resulting world rotation will be 270 degrees around the x-axis Signature fun rotateX(angleInDegrees: Float): TransformBuilder.TransformStepBuilder Parameters angleInDegrees: Float The rotation angle in degrees Returns TransformBuilder.TransformStepBuilder A TransformStepBuilder that can be used to chain additional transformations
rotateY ( angleInDegrees )	Creates a rotation transformation around the Y axis. Note that the rotation is applied as if looking from the rotation of the previous transformation, so if you rotated 180 degrees around the y-axis, then applied this transformation to rotate 90 degrees around the y-axis, the resulting world rotation will be 270 degrees around the y-axis Signature fun rotateY(angleInDegrees: Float): TransformBuilder.TransformStepBuilder Parameters angleInDegrees: Float The rotation angle in degrees Returns TransformBuilder.TransformStepBuilder A TransformStepBuilder that can be used to chain additional transformations
rotateZ ( angleInDegrees )	Creates a rotation transformation around the Z axis. Note that the rotation is applied as if looking from the rotation of the previous transformation, so if you rotated 180 degrees around the z-axis, then applied this transformation to rotate 90 degrees around the z-axis, the resulting world rotation will be 270 degrees around the z-axis Signature fun rotateZ(angleInDegrees: Float): TransformBuilder.TransformStepBuilder Parameters angleInDegrees: Float The rotation angle in degrees Returns TransformBuilder.TransformStepBuilder A TransformStepBuilder that can be used to chain additional transformations
sinDegrees ( angleInDegrees )	Helper function that calculates the sine of an angle specified in degrees. Signature fun sinDegrees(angleInDegrees: Float): Float Parameters angleInDegrees: Float The angle in degrees Returns Float The sine value of the angle
