Fixed slow runtime mesh creation

[Brutile]

To anyone creating mesh at runtime, like an endless terrain or something, you don't have to call Update() on the surface you just created. It was in the documentation, so I thought it was something you had to do when you created a model, but you only need to call model->UpdateAABB() with local and global parameters, like in the docs.

 

Updating the surface took around 15-20 milliseconds, which was causing frame drops when I was creating chunks of terrain, and there was nothing I could do to speed it up. But I tried it without surface->Update() and it now runs at a steady 100fps, instead of 100 and constantly dropping to 40fps.

 

Hope this helped a few people

Update() is rather thorough. It will calculate binormals/tangents, BSP collision for raycasts, and some other stuff.

 

Try calling UpdateBinormalsAndTangents() as well. I'm pretty sure the BSP collision will just recalculate itself only when needed.
