d2 

Returns the current square discriminant value. 

leftTransformation 

Returns the current left 3D non-linear transformation. 

rightTransformation 

Returns the current right 3D non-linear transformation. 

setD2 

Sets a new square discriminant value.
 

setLeftTransformation 

Sets a new left 3D non-linear transformation.
 

setRightTransformation 

Sets a new right 3D non-linear transformation.
 

transformPoint 

Evaluates a specified parameter using the following formula:
tmp_result = left_transformation.evaluate(param); output.x = tmp_result.x * cos(tmp_result.y * d2); output.y = tmp_result.x * sin(tmp_result.y *d2); output.z = tmp_result.z; output = right_transformation.evaluate(output);
