following constants can be used anywhere in your code in place of the actual values:
| Name | Value | Description |
|---|---|---|
| RF_CP_NON_RATIONAL | 1 | Indicating that rational control point and each X, Y and Z value represents Euclidian coordinate since it is already divided by W. |
| RF_CP_HOMOGENEOUS_RATIONAL | 2 | Indicating that rational control point and to make Euclidian coordinates each X, Y and Z coordinate should be divided by homogeneous coordinate W. |
| RF_CP_EUCLIDIAN_RATIONAL | 3 | Indicating that non-rational control point and it has no homogeneous coordinate W. |
