Start:


1. Log into Odin

2. Change to your /3480/9 folder.

Copy the lab files now...
cp /home/fac/gordon/p/3480/code/9/* .

Compile and run the program:
make
./lab9

We will write code together.

specular reflections
specular highlight
multiple lights
sky
animation

Homework

1. Make a new scene that you like
2. Create an animation

Your scene should have multiple objects.

Your animation must be a looping animation that runs forever
and you cannot tell where it starts or ends.

The bouncing ball is an example of an animation for this lab.

NEEDED FOR ANIMATION

include file
------------

#include <X11/Xutil.h>

X11_wrapper prototypes
----------------------

void getWindowAttributes(int *width, int *height);
XImage *getImage(int width, int height);

X11_wrapper member functions
----------------------------

void X11_wrapper::getWindowAttributes(int *width, int *height) {
    XWindowAttributes gwa;
    XGetWindowAttributes(dpy, win, &gwa);
    *width = gwa.width;
    *height = gwa.height;
}
XImage *X11_wrapper::getImage(int width, int height) {
    return XGetImage(dpy, win, 0, 0, width, height, AllPlanes, ZPixmap);
}

Sample of an animation technique
--------------------------------
    switch (key) {
        case XK_t:
            render();
            takeScreenshot("", 0);
            //move the sphere
            obj[1].pos.x += 10.0;
            render();
            takeScreenshot("", 0);
            //make a gif animation
			
            //create your gif animation like in lab6.cpp

            break;
