OpenGl_ShaderProgram::OpenGl_ShaderProgram | ( | const Handle< Graphic3d_ShaderProgram > & | theProxy = NULL , |
const TCollection_AsciiString & | theId = "" |
||
) |
Creates uninitialized shader program.
WARNING! This constructor is not intended to be called anywhere but from OpenGl_ShaderManager::Create(). Manager has been designed to synchronize camera position, lights definition and other aspects of the program implicitly, as well as sharing same program across rendering groups.
Program created outside the manager will be left detached from these routines, and them should be performed manually by caller.
This constructor has been made public to provide more flexibility to re-use OCCT OpenGL classes without OCCT Viewer itself. If this is not the case - create the program using shared OpenGl_ShaderManager instance instead.

Update the shader program from external files (per shader stage) in the following way: 1) If external file does not exist, then it will be created (current source code will be dumped, no recompilation) and FALSE will be returned. 2) If external file exists and it has the same timestamp as myDumpDate, nothing will be done and FALSE will be returned. 3) If external file exists and it has newer timestamp than myDumpDate, shader will be recompiled and relinked and TRUE will be returned.
