Function Documentation

void appendTextToBuffer ( char * tempStr )

void buildGL ( void )

Initializes OpenGL.

void createMenus ( )

void drawCStringGL ( char * cstrOut,

GLuint fontList

)

Draws a CString in OpenGL.

void drawGL ( pRecContext pContextInfo )

Main OpenGL drawing function.

void drawInfo ( pRecContext ) [static]

Displays the info on the screen.

pRecContext getCurrentContext ( )

void keyPressed ( unsigned char key,

int x,

int y

)

Called when a key is pressed, and no other keys are held down.

int main ( int argc,

char ** argv

)

void mouseDolly ( int x,

int y,

pRecContext pContextInfo

) [static]

void mouseMovedButton ( int x,

int y

)

Called when the mouse is moved with a button pressed down.

void mousePan ( int x,

int y,

pRecContext pContextInfo

) [static]

void mousePressedButton ( int button,

int state,

int x,

int y

)

Called when a mouse button is pressed.

int processFramesPerSecond ( char * argument[],

int maxNumArgs

)

void processMenuEvents ( int option )

void renderScene ( void )

Renders the scene.
Used by GLUT for it's display function. Wraps the drawGL() function.

void resizeGL ( pRecContext pContextInfo,

CGRect viewRect

)

Handles resizing of GL need context update and if the window dimensions change, a window dimension update, reseting of viewport and an update of the projection matrix.

void resizeWindow ( int x,

int y

)

Called when the window is resized.
Specific format for GLUT.

void submitTextToBuffer ( const char * val )

void updateModelView ( pRecContext pContextInfo )

Updates the viewpoint of the model.

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.
