| Static member | Description |
Decompose(...)
Signature: (trafo:Trafo3d * scale:byref<V3d> * rotation:byref<V3d> * translation:byref<V3d>) -> unit
|
Decomposes a transformation into a scale, rotation and translation component. NOTE: The input is assumed to be a valid affine transformation. The rotation output is in Euler-Angles (yaw, pitch, roll). |
GetModelOrigin(trafo)
Signature: trafo:Trafo3d -> V3d
|
Extracts the translation component of the given transformation, which when given a model transformation represents the model origin in world position. |
GetOrthoNormalOrientation(trafo)
Signature: trafo:Trafo3d -> Trafo3d
|
Builds an ortho-normal orientation transformation form the given transform. Scale and Translation will be removed and basis vectors will be ortho-normalized. NOTE: The X-Axis is untouched and Y/Z are forced to a normal-angle. |
GetScale(trafo)
Signature: trafo:M44d -> float
|
Approximates the uniform scale value of the given transformation (average length of basis vectors). |
GetScale(trafo)
Signature: trafo:Trafo3d -> float
|
Approximates the uniform scale value of the given transformation (average length of basis vectors). |
GetScaleVector(trafo)
Signature: trafo:M44d -> V3d
|
Extracts a scale vector from the given matrix by calculating the lengths of the basis vectors. NOTE: The extraction only gives absolute value (negative scale will be ignored) |
GetScaleVector(trafo)
Signature: trafo:Trafo3d -> V3d
|
Extracts a scale vector from the given matrix by calculating the lengths of the basis vectors. |
GetViewDirectionLH(trafo)
Signature: trafo:Trafo3d -> V3d
|
Extracts the Z-Axis from the given transformation. NOTE: A left-handed coordinates system transformation is expected, where the view-space z-axis points in forward direction. |
GetViewDirectionRH(trafo)
Signature: trafo:Trafo3d -> V3d
|
Extracts the Z-Axis from the given transformation. NOTE: A right-handed coordinates system transformation is expected, where the view-space z-axis points opposit the forward vector. |
GetViewPosition(trafo)
Signature: trafo:Trafo3d -> V3d
|
Extracts the inverse/backward translation component of the given transformation, which when given a view transformation represents the location of the camera in world space. |
