void | VuoTransform_getMatrix (const VuoTransform value, float *matrix) |
| Converts value into a column-major matrix of 16 values, composed as a rotation followed by a scale followed by a translation.
|
|
void | VuoTransform_invertMatrix4x4 (const float *matrix, float *outputInvertedMatrix) |
| Outputs the inverse of matrix (which is assumed to consist of a rotation followed by a scale followed by a translation, like the output of VuoTransform_getMatrix), such that outputInvertedMatrix * matrix = identityMatrix .
|
|
VuoPoint3d | VuoTransform_getEuler (const VuoTransform transform) |
| Returns the transform's rotation, represented as euler angles in radians (see VuoTransform_makeEuler).
|
|
VuoPoint4d | VuoTransform_getQuaternion (const VuoTransform transform) |
| Returns the transform's rotation, represented as a quaternion (see VuoTransform_makeQuaternion).
|
|
VuoPoint3d | VuoTransform_getDirection (const VuoTransform transform) |
| Start with an object pointing rightward (increasing X axis).
|
|
VuoTransform | VuoTransform_makeIdentity (void) |
| Creates a VuoTransform with no effect.
|
|
VuoTransform | VuoTransform_makeEuler (VuoPoint3d translation, VuoPoint3d rotation, VuoPoint3d scale) |
| Creates a VuoTransform from translation, rotation (Euler angles, in radians), and scale values.
|
|
VuoTransform | VuoTransform_makeQuaternion (VuoPoint3d translation, VuoPoint4d rotation, VuoPoint3d scale) |
| Creates a VuoTransform from translation, rotation (quaternion), and scale values.

|
VuoTransform | VuoTransform_makeFrom2d (VuoTransform2d transform2d) |
| Creates a 3D transform from a 2D transform.
|
|
VuoTransform | VuoTransform_makeFromTarget (VuoPoint3d position, VuoPoint3d target, VuoPoint3d upDirection) |
| Create a transform that translates to position and looks at target with roll determined by upDirection .
|
|
VuoTransform | VuoTransform_makeFromMatrix4x4 (const float *matrix) |
| Creates a transform from the specified matrix (assumed to consist of affine rotation, scale, and translation).
|
|
VuoRectangle | VuoTransform_transformRectangle (const float *matrix, VuoRectangle rectangle) |
| Transforms rectangle using matrix (a column-major matrix of 16 values), and returns the new rectangle.
|
|
void | VuoTransform_getBillboardMatrix (VuoInteger imageWidth, VuoInteger imageHeight, VuoReal translationX, VuoReal translationY, VuoInteger viewportWidth, VuoInteger viewportHeight, float *billboardMatrix) |
| Returns a column-major matrix of 16 values that transforms a 1x1 quad so that it renders the specified image at real (pixel-perfect) size.
|
|
VuoTransform | VuoTransform_composite (const VuoTransform a, const VuoTransform b) |
| Returns a composite transformation, consisting of a followed by b .
|
|
VuoPoint4d | VuoTransform_quaternionFromBasis (VuoPoint3d basis[3]) |

json_object * | VuoTransform_getJson (const VuoTransform value) |
| Encodes value as a JSON object.
|
|
char * | VuoTransform_getSummary (const VuoTransform value) |
| Produces a brief human-readable summary of value .
