moving into a openGL space

Mar 04 2009 | 1:38 pm

Hi all,
i’m trying to build a 3d universe and move the camera inside pointing the mouse on the direction i want to reach. I find it quite difficult. I’d like to giev some coordinates by pointing the mouse on the render window and control a speed parameter to move inside. The problem is feeding the right parameters to the camera base on its current position and "look at" vector. After some trigonometry i thought maybe getting information form the would be much easier. Anyone should have tried something similar. Any idea/code sample on how to do that?
Any discussion is much appreciated, i see it quite challenge for me!

I don’t know if it could help you, but you should have a look at AdvancedCamera.pat example?

Thanks Kyred it looks really nice! I’ll have a look… Did not think it could be so difficult… but it’s a good starting point saving me lots of maths!

I’ve made several different GL navigators here that allow you to fly around 3D-engine-like.

Processing versions available here:

Here’s a click-and-drag camera rotation patch that I just whipped up. Made something like this in Processing and have been meaning to put a Max version together. So here it is. Hope someone finds it useful!

Hi Zach, thanks i’ll try your stuff soon. In the mean time i managed to modify the "advanced camera" example and it works quite fine. But i can always learn from more experience user! By the way would it be possible for you to re-post the previous patch in max 4 format? I’m still old school Wink.

Here’s a snapshot of the Max5 patch. You can download the patch and run it through that SC converter script – that should work as there are no Max5-only objects.

Great Thanks

I just made it into an abstraction, for ease of use. I’ve attached it here, and also included it in my abstraction package on the website. Picture included as well.
