canvas_vektor's Issues

Sort polygons on Z

For the filled polygon rendering, polygons needs to be sorted on the Z axis - then draw from back to front.

Center the Object

Create a function which centers the 3D Object vertex in the 3D Space.
All rotation should follow only after this centralization / normalization.

metacode:

function center(vertexObj) { 
   for min...max { 
      xmin = min (xmin, vertexObj[i][x])
     xmax = max (xmax, vertexObj[i]x]) 
     ymin = ..
      zmin = ..
   } 
   xcenter = xmin+((xmax-xmin)/2);
   vertexObj = shiftX(vertexObj, -xcenter);
  ...
return targetObj;
}

Add perspective

Everything looks better if perspective is added to the renderer instead of the axonometric view.
