Hi,
Here is a simple VR set-up
Here is an example of it uploaded
http://www.trump.net.au/members/ship...example3D.html
And here is the code. I am sure you will have a number of questions to ask in order to use this code for your purposes. So I will await your questions.
The following code is all there is to the example if you want to play with it. I don't think I can make it much simpler than this. All aspects can be extended if needed.
Code:function Vect3(x,y,z){ this.x=x; this.y=y; this.z=z; }; Vect3.prototype.Set=function(x,y,z){ this.x=x; this.y=y; this.z=z; }; function Matrix3x3(){ this.xx=1; this.xy=0; this.xz=0; this.yx=0; this.yy=1; this.yz=0; this.zx=0; this.zy=0; this.zz=1; }; Matrix3x3.prototype.Set=function(a,b,c,d,e,f,g,h,i){ this.xx=a; this.xy=b; this.xz=c; this.yx=d; this.yy=e; this.yz=f; this.zx=g; this.zy=h; this.zz=i; }; Matrix3x3.prototype.SetRotation=function(x,y,z){ var a = Math.cos(x*(Math.PI/180));//x plane var b = Math.sin(x*(Math.PI/180)); var c = Math.cos(y*(Math.PI/180));//y plane var d = Math.sin(y*(Math.PI/180)); var e = Math.cos(z*(Math.PI/180));//z plane var f = Math.sin(z*(Math.PI/180)); this.xx=(c*e); this.xy=(b*d*e+a*f); this.xz=(-a*d*e+b*f); this.yx=(-c*f); this.yy=(-b*d*f+a*e); this.yz=(a*d*f+b*e); this.zx=d; this.zy=(-b*c); this.zz=(a*c); }; function Object3D(){ this.Position=new Vect3(0,0,0); this.Orientation=new Matrix3x3(); }; Object3D.prototype.AddVertices=function(vertices){ this.vertList=vertices; };
