C++ (Cpp) initShadowMaps Examples

Example #1

File: Stage.cpp Project: jejatu/3d

void Stage::run(void) {
	initGL();
	initShadowMaps();

	m_lastTime = glfwGetTime();
	m_running = true;
	while (m_running) {
		double currentTime = glfwGetTime();
		// limit fps
		if (m_framerate == 0 || currentTime - m_timer > 1.0f / float(m_framerate)) {
			update(currentTime);
			if (m_camera != 0) render();
		}
	}
}
