Viewport

dojox.gfx3d.Viewport (Viewport in the following⁴) is the container for all 3D objects, created by the exported static function, createViewport:

      dojox.gfx3d.createViewport(parentNode, width, height)

Viewport would expose the following interfaces to create basic 3D objects:

      dojox.gfx3d.Viewport.createLine(start, end)
      dojox.gfx3d.Viewport.createPath(path)
      dojox.gfx3d.Viewport.createTriangle(a, b, c)

and some high level objects as well:

      dojox.gfx3d.Viewport.createCube(upper, lower)
      dojox.gfx3d.Viewport.createCylinder(top, bottom, r)
      dojox.gfx3d.Viewport.createPipe(path, r)
      dojox.gfx3d.Viewport.createCone(top, bottom, r)

Viewport is the container of 3D objects, and also the environment and viewport.

      dojox.gfx3d.Viewport.setCamera(camera)
      dojox.gfx3d.Viewport.addLighting(lighting)

We may steal more ideas from Pov-Ray⁵

Viewport is also our home-brewed 3D engine, with the folowing services exported:

      dojox.gfx3d.Viewport.applyCameraTransform(point)
      dojox.gfx3d.Viewport.renderLighting(surface, texture)
