Hi Andres,

I'm having the same problem as original poster in this thread. I'm working on a project with Kinect using SimpleOpenNI, which returns PMatrix3D for joint orientations. I'm rendering limbs as separate GLModels (Processing 1.5.1) so I need to find a way to either use rotateX, rotateY and rotateZ instead of applyMatrix, or use gl.glMultMatrixf as in this thread on SourceForge.
To complicate things even further, I'm first drawing all models in an GLGraphicsOffscreen buffer, where applyMatrix doesn't seem to be implemented. Would it be possible to do it using example in the above mentioned link and how?
I still have enough time to upgrade to Processing 2.0, should you suggest this would be best.

Cheers and thanks for your answers!

edit: I solved it with glMultiMatrixf

void applyGLMatrix (PMatrix3D o, GL gl) {
  float[] gltemp = new float[16];
  gltemp[0] = o.m00; //n00;
  gltemp[1] = o.m10; //n10;
  gltemp[2] = o.m20; //n20;
  gltemp[3] = o.m30; //n30;
  gltemp[4] = o.m01; //n01;
  gltemp[5] = o.m11; //n11;
  gltemp[6] = o.m21; //n21;
  gltemp[7] = o.m31; //n31;
  gltemp[8] = o.m02; //n02;
  gltemp[9] = o.m12; //n12;
  gltemp[10] = o.m22; //n22;
  gltemp[11] = o.m32; //n32;
  gltemp[12] = o.m03; //n03;
  gltemp[13] = o.m13; //n13;
  gltemp[14] = o.m23; //n23;
  gltemp[15] = o.m33; //n33;
  gl.glMultMatrixf(gltemp, 0);
}
