适用于Android的OpenGL ES2-奇怪的随机突起

Question

I'm just starting to learn OpenGL ES2 for Android, and have come across a weird problem where sometimes a weird jut will be rendered from my objects (see pic). This doesn't always happen, which is strange, so I'm wondering if anyone has any experience with this sort of thing and how to fix it.

Answer 1

The problem here was that I was calling GLES20.glDrawArrays(type, first, count) with an incorrect count. Setting the variable correctly fixed it.
