AppGameKit Classic Chat / Not a lot of culling going on ...

I was surprised to see that as I zoomed in on one of my ships in my test app that the FPS remained pretty much the same (second screenshot). So I added a few lines of code to hide the outer 10 ships manually when the camera gets close to my centre ship, and look at the FPS increase!

So does anyone know if AppGameKit does any culling at all? Here's hoping there is some basic off screen culling in V2 if there isn't in V1.

I assumed there was some simple culling in 3D but it looks like there isn't. That's quite a difference in speed!

I'm wondering if perhaps the vast array of resolutions supported has affected the on/off screen detection, and perhaps it does cull eventually. In any case, it's a heads up to anyone making a game with 3D. Some manual culling should see some serious performance benefits. Luckily with Dreadcom the perspective will be simple enough for me to calculate the culling without having to learn a load of new math formulae.

The 3D in version 1 was thrown together very quickly and isn't very efficient. It doesn't do any culling or batching, but this will be addressed in version 2.

Good to know Paul! Thanks for letting us know. I'll forget about any custom culling in lieu of version 2.

Oh, that is such good news! I've been experimenting with manual culling-routines, but am finding AppGameKit a lot more slow then DBPro. This will help a lot. Am I right in assuming the culling will be part of the 3D-phase of AppGameKit V2 (estimation on Kickstarter-page is january 2014)?

That is actually nice to hear, as I was fairly impressed with it's speed in the main. Nice to know there is good room for improvement!
