I want to make a 3D heart,append at least two effects to the heart, such as materials, lights, and so on.And make an animation by using the heart,and the animation are supposed to make good sense. My Imagination is:the heart can move.Run up against walls,after several collisions the heart became larger.it means after hardships and dangers one man can be stronger.
I'VE FINISHED A 3D HEART, BUT WITHOUT MATERIALS OR ANIMATION:
%(x^2 + (9/4)y^2 + z^2 - 1)^3 - x^2z^3 - (9/80)y^2z^3 = 0 -3<=x,y,z<=3
[x,y,z]=meshgrid(linspace(-3,3)); %做出网格meshgrid
p=(x.^2+(9/4)*y.^2+z.^2-1).^3-x.^2.*z.^3-(9/80)*y.^2.*z.^3; %实现结果的表达
isosurface(x,y,z,p,0); %使用函数做图mesh surf
axis equal;
axis off;
view(0,35); %视角的控制
colormap([1 0 0]); %绘图颜色红色
brighten(1.0); %增亮
camlight left; %光源位置
lighting p; %光照模式
HERE IS WHAT I'VE SEARCHED IN THE INTERNET,ABOUT A BALL RUNNING UP AGAINST A WALL
figure(1);%定义函数
axis([-5.1,5,-0.05,1.05]);%绘制二维图形
hold on;%保持当前图形及轴系所有的特性
axis('off');%覆盖坐标刻度，并填充背景
%通过填充绘出台阶及两边的挡板

How can I come achieve my imagination?If it is impossible,similarity is OK I start studying matlab for only a short time.THANX for your help!
