C++ (Cpp) Matrix44f::get_ptr Beispiele

Beispiel #1

Datei: frustum.cpp Projekt: otaviog/UdToolkit

void Frustum::ExtractFromOGLState() {
  Matrix44f modelview;
  Matrix44f projection;

  glGetFloatv(GL_MODELVIEW_MATRIX, modelview.get_ptr());
  glGetFloatv(GL_PROJECTION_MATRIX, projection.get_ptr());

  Extract(projection * modelview);
}

Beispiel #2

Datei: test_volume.cpp Projekt: otaviog/UdToolkit

  void DrawRaytraceVolume() {
    glLoadIdentity();

    Matrix44f modelview;
    m_camera.GetMatrix(&modelview);

    Matrix44f projection;

    glMatrixMode(GL_PROJECTION);
    glLoadIdentity();
    gluPerspective(45.0f, Projection::AspectRatio(width(), height()), 0.1, 100.0f);
    glGetFloatv(GL_PROJECTION_MATRIX, projection.get_ptr());
    glMatrixMode(GL_MODELVIEW);

#if 0
