Different Gladius Shapes

‹prev | My Chain | next›

I am a tad weary of squares and pyramids in Gladius. Tonight I would like to generate something a little different. How about a nice, simple sphere?

Well, looking through the CubicVr.js Primitives class, it does not seem like a simple thing to do manually. The sphere primitive calculates sever point around the center in order to call a "lathe" primitive to actually build the mesh. That seems... hard manually.

So how do I access the sphere primitive from the gladius-cubicvr.js?

At first I try:

require(['gladius-core', 'gladius-cubicvr'],
  function(Gladius, cubicvrExtension){
  // ...
  var resources = {
    mesh: cubicvrExtension.sphere(),
    material: {
      textures: {
        color: '/images/rygb.png'
      }
    }
  };

  game.bind( null, engine, resources );
  // ...
}

By virtue of require.js, I have access to the cubicvrExtension object. It would be nice if the sphere() primitive just exists on that extension. Unfortunately, when I load the thing in the browser, I see the following in the Javascript console:

Uncaught TypeError: Object #<Object> has no method 'sphere'

That would be too easy. Digging through the code, I find that Mesh can generate a sphere with the right primitive. I find a Mesh function in the cubicvr Gladius extension and try to use it like this:

  var Mesh = cubicvrExtension.services.renderer.resources.Mesh;
  var resources = {
    mesh: Mesh({
     primitive: {
       type: "sphere",
       radius: 0.5,
       lat: 24,
       lon: 24,
       material: {
         textures: {
           color: '/images/rygb.png'
         }
       }
     }
    })
  };

Unfortunately, that turns out to be the wrong Mesh. I have to call it a night here, but I will keep digging for an easy way to generate primitive shapes in Gladius + CubicVR.js.
