Performing Transforms
createTransformation
Creates a new Transformation object (t) that can be used to transform a shape (Wire, face, Solid etc). This is a more of generic method that lets you specify more than one type of transformation in one call. Refer to other methods that allow only one type of transform.
Note: When your intent is to use objects center as center of transform, use a flavor that captures only transformation information. If you intend to use a particular point for rotation, then construct a transform that lets you specify center and Qauternion.
Syntax
cadlib.createTransformation( { position: {x, y,z }, quaternion: { x, y, z, w}, scale: { factor: N } } );
Parameters
| Name | Type | Description |
|---|---|---|
| position | Vec3 | Optional. Include this to add positional transformation |
| quaternion | Quaternion | Optional. Include this to add rotation transformation (x, y, z, w). w is in Radians and must be greater than 0 |
| scale | Object | Optional. Include to specify scaling factor. |
Returns
Example

createRotationTransform
Construct a rotation transformation using center of rotation, axis and angle information.
Note: Use this method when you want rotation around a specific point (center).
Syntax
cadlib.createRotationTransform( center, axis, angle );
Parameters
| Name | Type | Description |
|---|---|---|
| center | Vector3 | center of rotation |
| axis | Vector3 | axis of rotation |
| angle | Number | rotation angle |
Returns
Transformation
crateQuaternionTransform
Create a rotation transform using the specified Quaternion. Supply value for center point if rotation around a specific point is needed. Otherwise, objects center will be used.
Syntax
cadlib.crateQuaternionTransform(quanternion, center);
Parameters
| Name | Type | Description |
|---|---|---|
| quaternion | [Quaternion] | Include this to add rotation transformation (x, y, z, w). w is in Radians and must be greater than 0 |
| center | Vec3 | Center of rotation |
Returns
Transformation(./)
createTranslationTransform()
Creates a translation transform.
Syntax
cadlib.createTranslationTransform(x, y, z);
Parameters
| Name | Type | Description |
|---|---|---|
| x | Point | Translation along X axis |
| y | Point | Translation along Y axis |
| z | Point | Translation along Z axis |
Returns
createMrrorAxisTransform()
Used to mirror an solid around an axis with specified center
Syntax
cadlib.createMrrorAxisTransform(center, axis);
Parameters
| Name | Type | Description |
|---|---|---|
| center | Point | Center point for the mirror |
| axis | Vec3 | Mirror Axis |
Returns
createScaleTransform()
Use this transform to scale an solid.
Syntax
cadlib._createScaleTransform(factor, center);
Parameters
| Name | Type | Description |
|---|---|---|
| factor | Number | Scaling factor. Solid will be scaled uniformly |
| center | Pont | center of scaling |
Returns
scale()
Use this method to scale a solid.
Note: This method accepts a shape/solid unlike createScaleTransform
Syntax
cadlib.scale(shape, factor, center);
Parameters
| Name | Type | Description |
|---|---|---|
| shape | [Face, Wire, Edge, Solid] | Shape to scale |
| factor | Number | Scaling factor. Solid will be scaled uniformly |
| center | Pont | center of scaling |
Returns
Shape – Returns scaled shape (Face, Wire, Edge or Solid)
