Function Documentation

appDemoLoadScene()

void appDemoLoadScene	(	SLAssetManager *	am,
		SLScene *	s,
		SLSceneView *	sv,
		SLSceneID	sceneID
	)

Forward declaration of the scene definition function from AppDemoLoad.cpp.

Forward declaration of the scene definition function from AppDemoLoad.cpp.

appDemoLoadScene builds a scene from source code. Such a function must be passed as a void*-pointer to slCreateScene. It will be called from within slCreateSceneView as soon as the view is initialized. You could separate different scene by a different sceneID.
The purpose is to assemble a scene by creating scenegraph objects with nodes (SLNode) and meshes (SLMesh). See the scene with SID_Minimal for a minimal example of the different steps.

createAppDemoSceneView()

SLSceneView * createAppDemoSceneView	(	SLScene *	scene,
		int	curDPI,
		SLInputManager &	inputManager
	)

Alternative SceneView creation C-function passed by slCreateSceneView.

initGLFW()

void initGLFW	(	int	screenWidth,
		int	screenHeight
	)

Initialises all GLFW and GL3W stuff.

initSL()

void initSL

(

SLVstring &

cmdLineArgs

)

Inits all for SLProject library.

main()

int main	(	int	argc,
		char *	argv[]
	)

The C main procedure running the GLFW GUI application.

mapKeyToSLKey()

SLKey mapKeyToSLKey

(

SLint

key

)

Maps the GLFW key codes to the SLKey codes.

onCharInput()

void onCharInput	(	GLFWwindow *	,
		SLuint	c
	)

Event handler for GLFW character input.

onClose()

void onClose

(

GLFWwindow *

myWindow

)

onClose event handler for deallocation of the scene & sceneview. onClose is called glfwPollEvents, glfwWaitEvents or glfwSwapBuffers.

onGLFWError()

void onGLFWError	(	int	error,
		const char *	description
	)

Error callback handler for GLFW.

onKeyPress()

static void onKeyPress ( GLFWwindow *  myWindow, int  GLFWKey, int  scancode, int  action, int  mods  )

static

Key event handler sets the modifier key state & forwards the event to the slKeyPress function.

onMouseButton()

static void onMouseButton ( GLFWwindow *  myWindow, int  button, int  action, int  mods  )

static

Mouse button event handler forwards the events to the slMouseDown or slMouseUp. Two finger touches of touch devices are simulated with ALT & CTRL modifiers.

onMouseMove()

static void onMouseMove ( GLFWwindow *  myWindow, double  x, double  y  )

static

Mouse move event handler forwards the events to slMouseMove or slTouch2Move.

onMouseWheel()

static void onMouseWheel ( GLFWwindow *  myWindow, double  xscroll, double  yscroll  )

static

Mouse wheel event handler forwards the events to slMouseWheel

onPaint()

SLbool onPaint

(

)

onPaint: Paint event handler that passes the event to the slPaint function.

onResize()

static void onResize ( GLFWwindow *  myWindow, int  width, int  height  )

static

onResize: Event handler called on the resize event of the window. This event should called once before the onPaint event.

onUpdateVideo()

bool onUpdateVideo

(

)

Implements the update per frame for video update and feature tracking.

This routine is called once per frame before any other update within the the main rendering loop (see: AppDemoMainGLFW::onPaint or GLES3View::onDrawFrame). See the documentation within SLCVTracked and in all of its inheritants.
