How to fix screen tearing in cocos3d?

Question

When I get the camera closer to some objects in the scene the image tears apart like it's shown below.

I'm using OpenglES 2.0

This is a video showing the issue.

And this is the test project that reproduce the issue, it's just the cocos3d template with the temple.pod file.

It seems that it only happens when the field of view is 85º or wider.

From what I can tell by running your demo, the "tearing" appears to be occurring as the near clipping plane of your camera breaches your model. Essentially, it is a result of the camera entering your model.

The CC3Camera nearClippingDistance property controls the distance to the camera's near clipping plane. The default value is 1.0. If the coordinate scale of your scene is very small, then you should adjust the near and far clipping distances of the camera to values more suitable for your scene.
