Typedef Documentation

CommandLineCallback

typedef int(* CommandLineCallback) (char **, int)

A command-line callback handler takes in a char** which points to the argument which matches the argument that this handler was installed for.

The second argument is the number of remaining arguments available. The handler can process and use as many of the remaining arguments, and returns the number of arguments it processed.

Definition at line 206 of file Common.h.

FrameCallback

typedef void(* FrameCallback) (unsigned long windowID, unsigned int viewport, void *)

install a FrameCallback to be called once per frame and viewport This is where you should do any drawing and/or update the unit simulation time.

The viewports will be processed in order (0..#, max 4), so any global processing should only be done when the viewport is 0. The void* data is passed back to each call.

Definition at line 170 of file Common.h.

JoystickCallback

typedef void(* JoystickCallback) (unsigned long windowID, double offsetX, double offsetY, void *)

a joystaick callback handler is passed the same data passed in when it was installed

Definition at line 180 of file Common.h.

KeyboardCallback

typedef void(* KeyboardCallback) (unsigned long windowID, tKeyboardModifier, char)

a keyboard callback handler is passed the current unit simulation, the key that was hit, and any modifiers that were being held down.

Note that the modifiers can change the character being passed.

Definition at line 198 of file Common.h.

MouseCallback

typedef bool(* MouseCallback) (unsigned long windowID, int x, int y, point3d loc, tButtonType, tMouseEventType)

a mouse callback handler passes the absolute and local mouse coordinates of the click returns true if the click/movement was handled; false if ignored

Definition at line 186 of file Common.h.

MouseCallback2

typedef bool(* MouseCallback2) (unsigned long windowID, int viewport, int x, int y, point3d loc, tButtonType, tMouseEventType)

the new callback handler also passes the viewport frame in which the click occured.

The loc is relative to the frame which was clicked

updateProjection()

void updateProjection	(	pRecContext	pContextInfo,

	)

Update the projection matrix based on camera and view info.

Should be called when viewport size, eye z position, or camera aperture changes. Also call if far or near changes which is determined by shape size in this case.
