Detailed Description

ITransform3 handles homogeneous 4x4 transforms, i.e. transformations which can be represented by multiplying a 4x4 matrix with a homogeneous 3D coordinate.
ITransform3 can either pre-multiply a matrix onto the transformation, which will add a transform around the current transform, or it can post-multiply the matrix, which will add a transform inside the current transform. Post-multiply is the default mode.

Clear()

virtual void SimplygonSDK::ITransform3::Clear ( )

pure virtual

Resets the transformation to the identity transform, resets the multiplication mode to postmultiply, and clears the matrix stack

GetClass()

virtual const char* SimplygonSDK::ITransform3::GetClass ( )

virtual

GetClass returns the name of the class of the object.

Returns

the name of the actual class of the object, as a const char string

Reimplemented from SimplygonSDK::IObject.

GetMatrix()

virtual CountedPointer<IMatrix4x4> SimplygonSDK::ITransform3::GetMatrix ( )

pure virtual

Get the matrix that is used to specify the transform

Returns

the transform matrix

GetStack()

virtual CountedPointer<IRealArray> SimplygonSDK::ITransform3::GetStack ( )

pure virtual

Get the real array that is used to store the matrix stack

Returns

the matrix stack array

IsA()

virtual bool SimplygonSDK::ITransform3::IsA ( const char *  type ) const

virtual

The IsA function returns true if the object is a or is a descendant of the class named as the type parameter

Parameters

type	is the name of the class to check if the object is, or is a descendant of

Returns

true if the object is of the specified class, false if not

Reimplemented from SimplygonSDK::IObject.

IsClassA()

static bool SimplygonSDK::ITransform3::IsClassA ( const char *  type )

inlinestatic

The IsClassA function returns true if ITransform3 is a or is a descendant of the class named as the type parameter

Parameters

type	is the name of the class to check if the class is, or is a descendant of

Returns

true if the class is of the specified class, false if not

Definition at line 7500 of file SimplygonSDK.h.

IsPostMultiply()

virtual bool SimplygonSDK::ITransform3::IsPostMultiply ( )

pure virtual

Get the transform concatenation mode.

Returns

true if the mode is set to post-multiply, false otherwise

IsPreMultiply()

virtual bool SimplygonSDK::ITransform3::IsPreMultiply ( )

pure virtual

Get the transform concatenation mode.

Returns

true if the mode is set to pre-multiply, false otherwise

Pop()

virtual void SimplygonSDK::ITransform3::Pop ( )

pure virtual

Pops the topmost matrix on the the matrix stack, and replaces the current transform with the popped matrix.

PostMultiply()

virtual void SimplygonSDK::ITransform3::PostMultiply ( )

pure virtual

Set the transform concatenation mode to post-multiply, any added transform will be concatenated using this mode.

PreMultiply()

virtual void SimplygonSDK::ITransform3::PreMultiply ( )

pure virtual

Set the transform concatenation mode to pre-multiply, any added transform will be concatenated using this mode.

Push()

virtual void SimplygonSDK::ITransform3::Push ( )

pure virtual

Pushes the current transform onto the matrix stack

SafeCast()

static ITransform3* SimplygonSDK::ITransform3::SafeCast ( IObject *  ptr )

inlinestatic

SafeCast makes sure the pointer is of a class that can be cast into a ITransform3 pointer, and if this is possible, returns the cast pointer.

Parameters

ptr	is the pointer to be cast into a ITransform3 pointer

Returns

a pointer to the ITransform3 object, if the cast can be made, and a NULL pointer otherwise
