Constructors:

osg.Matrix()

osg.Matrix(osg.Matrix v)

Parameters:v (osg.Matrix) –
osg.Matrix(osg.RefMatrix v)

osg.Matrix(double a00, double a01, double a02, double a03, double a10, double a11, double a12, double a13, double a20, double a21, double a22, double a23, double a30, double a31, double a32, double a33)

Parameters:
  • a00 (double) –
  • a01 (double) –
  • a02 (double) –
  • a03 (double) –
  • a10 (double) –
  • a11 (double) –
  • a12 (double) –
  • a13 (double) –

Methods:

:transpose(osg.Matrix rhs)

Parameters:rhs (osg.Matrix) –
Return type:bool
:setTrans(osg.Vec3 trans)

Parameters:trans (osg.Vec3) –
:getTrans()

Return type:osg.Vec3
:setRotate(osg.Quat rot)

Parameters:rot (osg.Quat) –
:getRotate()

Get the matrix rotation as a osg.Quat. Note that this function assumes a non-scaled osg.Matrix and will return incorrect results for scaled matrixces. Consider osg.Matrix.decompose() instead.

Return type:osg.Quat
:getScale()

Return type:osg.Vec3
:preMult(osg.Matrix matrix)

Parameters:matrix (osg.Matrix) –
:postMult(osg.Matrix matrix)

Parameters:matrix (osg.Matrix) –
:getItem(unsigned row, unsigned column)

Parameters:
  • row (unsigned) –
  • column (unsigned) –
Return type:

double
:setItem(unsigned row, unsigned column, double val)

Parameters:
  • row (unsigned) –
  • column (unsigned) –
  • val (double) –
:decompose()

Decompose the matrix into translation, rotation, scale and scale orientation.

:getPerspective()

Get the frustum settings of a symmetric perspective projection matrix. Return false if matrix is not a perspective matrix, where parameter values are undefined. Note, if matrix is not a symmetric perspective matrix then the shear will be lost. Asymmetric matrices occur when stereo, power walls, caves and reality center display are used. In these configuration one should use the AsFrustum method instead.

:makeLookAt(osg.Vec3 eye, osg.Vec3 center, osg.Vec3 up)

Set the position and orientation to be a view matrix, using the same convention as gluLookAt (https://www.khronos.org/registry/OpenGL-Refpages/gl2.1/xhtml/gluLookAt.xml).

Parameters:
:isNaN()

Return type:bool
:identity()

:isIdentity()

Return type:bool

Static Methods:

.identity()
