C++ (Cpp) glCOLOR Examples

Example #1

File: Gfx_wrapper_OpenGL.cpp Project: DrItanium/Serious-Engine

// set constant color (and force rendering w/o color array!)
static void ogl_SetConstantColor( COLOR col)
{
  ASSERT( _pGfx->gl_eCurrentAPI==GAT_OGL);
  ogl_DisableColorArray();
  _sfStats.StartTimer(CStatForm::STI_GFXAPI);

  glCOLOR(col);
  OGL_CHECKERROR;

  _sfStats.StopTimer(CStatForm::STI_GFXAPI);
}

Example #2

File: RenderModel.cpp Project: 0-T-0/Serious-Engine

  // prepare wireframe OpenGL settings
