o3d（webgl）投影的最大远平面是多少？

Question

Hi,

I am using the following javascript...

  g_viewInfo.drawContext.projection = g_math.matrix4.perspective(
      g_math.degToRad(30), // 30 degree fov.
      g_client.width / g_client.height,
      1,                  // Near plane.
      9999);              // Far plane.

Can anyone tell me what the maximum far plane of an o3d (webgl) projection is?

I have tried using 5000 and 9999 but everything still seems to disappear at the same point. I have tried to locate this information in the SDK's current documentation.

Is there a reason for such a weak limitation?
Is it possible to hack the max value?
