Detailed Description

The SubdivSchemeModifier class is visually represented by the small viewer window in the "Modifier" menu of the "Div" tab of the MultiResMeshEditor interface. It is used to symbolically visualize a subdivision scheme's transformations and modify these transformations. The modifications are of a different nature than those performed by the SubdivSchemeEditor : the SubdivSchemeModifier does not change the matrices' coefficients but performs rotation/symetries of these transformations in the UVW space.
The actions performed in the SubdivSchemeModifier will be transmitted to the current subdivision scheme used in the MultiResMeshEditor via signals and slots.

Constructor & Destructor Documentation

SubdivSchemeModifier::SubdivSchemeModifier ( QWidget *  parent,
const char *  name 
)

Basic constructor : The SubdivSchemeModifier is a QOBJECT

Member Function Documentation

void SubdivSchemeModifier::draw (  )  [protected, virtual]

Symbolically draws activated transformation in big, deactivated transformations in small, in a UVW grid

void SubdivSchemeModifier::drawTransfo ( int  u,
int  v,
int  w 
) [protected]

Draws the transformation symbol (pyramid like shape)

void SubdivSchemeModifier::drawWithNames (  )  [protected, virtual]

Uses PushNames to render drawn elements selectable

void SubdivSchemeModifier::fastDrawQuad ( Vec  P1,
Vec  P2,
Vec  P3,
Vec  P4 
) [protected]

Draws a quad (no shit Sherlock)

void SubdivSchemeModifier::init (  )  [protected, virtual]

Initializes class attributes and openGL viewing parameters.

Vec SubdivSchemeModifier::MatriceVecMultiply ( SSMatrix  M,
Vec  V 
) [protected]

Operator that multiplies a Vec with a SSMatrix, applies transformation to a point in IR^3

SubdivSchemeModifier::RotateU (  )  [protected]

See also:
RotateW

SubdivSchemeModifier::RotateV (  )  [protected]

See also:
RotateW

SubdivSchemeModifier::RotateW (  )  [protected]

Changes the matrix to make this transformation rotate on W
columns of the matrix are permutated in such a way that the transformation
which would have given the patch :
+ P10 + P11


+ P00 + P01
^ V
|
|
---> U

now gives the patch :
+ P10 + P11


+ P00 + P01
---> V
|
|
v U

SubdivSchemeModifier::S_Activate (  )  [slot]

Activates or desactivates the selected transformation. Deactivated transformations will not take part in a subdivision iterration

void SubdivSchemeModifier::S_ActivateTransfo ( int  Uindice,
int  Vindice,
int  Windice 
) [signal]

These signals are used to signify to the MultiResMeshEditor when a transformation has been modified via the SubdivSchemeModifier

SubdivSchemeModifier::S_ResetSubdivSchemeModifier ( int  NbTU,
int  NbTV,
int  NbTW 
) [slot]

Deletes all transformation modification, rebuilds initial data with no modifications

SubdivSchemeModifier::S_Rotate (  )  [slot]

Rotates the selected transformation around the selected UVW axis

void SubdivSchemeModifier::S_RotateTransfo ( int  Uindice,
int  Vindice,
int  Windice,
int  Axis 
) [signal]

These signals are used to signify to the MultiResMeshEditor when a transformation has been modified via the SubdivSchemeModifier

SubdivSchemeModifier::S_Symmetrise (  )  [slot]

Performs a symetry of the selected transformation across the selected UVW plane

void SubdivSchemeModifier::S_SymmetriseTransfo ( int  Uindice,
int  Vindice,
int  Windice,
int  Axis 
) [signal]

These signals are used to signify to the MultiResMeshEditor when a transformation has been modified via the SubdivSchemeModifier

SubdivSchemeModifier::S_ToggleCurrentAxis ( int  A  )  [slot]

Changes the current axis (U:0, V:1, W:2)

See also:
_CurrentAxis

SubdivSchemeModifier::SymmetriseU (  )  [protected]

Changes the matrix to perform a symetry on W
Columns of the matrix are permutated in such a way that the transformation which would have given the patch :
+ P10 + P11


+ P00 + P01
^ V
|
|
---> U

now gives the patch :
+ P10 + P11


+ P00 + P01

^ V
|
|
U <---

SymmetriseU
