This is what i got until now:
#get camera inverse matrix
camView = om.MDagPath()
view.getCamera( camView )
cameraInverseMatrix =
camView.inclusiveMatrix().inverse()
#convert matrix to MGLfloat *
proMat = cameraInverseMatrix
matrixToDouble =
[om.MScriptUtil.getDoubleArrayItem(proMat[0],0),
om.MScriptUtil.getDoubleArrayItem(proMat[0],1),
om.MScriptUtil.getDoubleArrayItem(proMat[0],2),
om.MScriptUtil.getDoubleArrayItem(proMat[0],
3),om.MScriptUtil.getDoubleArrayItem(proMat[1],0),
om.MScriptUtil.getDoubleArrayItem(proMat[1],1),
om.MScriptUtil.getDoubleArrayItem(proMat[1],2),
om.MScriptUtil.getDoubleArrayItem(proMat[1],
3),om.MScriptUtil.getDoubleArrayItem(proMat[2],0),
om.MScriptUtil.getDoubleArrayItem(proMat[2],1),
om.MScriptUtil.getDoubleArrayItem(proMat[2],2),
om.MScriptUtil.getDoubleArrayItem(proMat[2],
3),om.MScriptUtil.getDoubleArrayItem(proMat[3],0),
om.MScriptUtil.getDoubleArrayItem(proMat[3],1),
om.MScriptUtil.getDoubleArrayItem(proMat[3],2),
om.MScriptUtil.getDoubleArrayItem(proMat[3],3)]
suFloatArray = om.MScriptUtil()
suFloatArray.createFromList( matrixToDouble, 16 )
suPointer = suFloatArray.asFloatPtr()
test = glFT.glGetFloatv(omRender.MGL_MODELVIEW,
suPointer )
#set camera matrix to opengl
glFT.glPushMatrix()
#glFT.glLoadMatrixd( test )#>>>CRASH
#start render
glFT.glBegin( omRender.MGL_LINES )
for i in range(0,360,10):#step 10
rad = (i*2*math.pi)/360;
glFT.glVertex2f(math.sin(rad)*radius,math.cos(rad)*radius)
glFT.glEnd()
But it crash when i'm applying the matrix: "glFT.glLoadMatrixd( test )"
