A problem with the rendering of a certain model.

[nashiro66]

I'm interested in your research, and I tried using the Stanford Bunny model available here (https://ptex.us/samples.html) to convert it from .ptx to .htx format with ptx2htx. After using htxview to render the model, I thought the rendering was successful.

However, when I tried zooming in, the result appeared to be jumbled and chaotic even if we consider the filter mode. What could be the cause of this issue? The top image is the result of htx drawing and the bottom is the result of ptx drawing. Are these results correct?

I would appreciate any advice you could give me.
