Jitter GL Camera help

Is there any way to get a first person view - or get the camera to react as a rigid body within the physics engine?

HI. That's a fairly advanced question. I can't help, and experience has been you may have to wait a while for a response when you're pushing the frontier a little, but don't be discouraged. And it may be some others are active on that, but it may not be very many people.

[jit.anim.camera] might provide some usefuls things for you, after that you'll probably need some jit.phys magic somewhere... atually i'm trying to do teh same thign, it's not easy...

Hi

Maybe this can help you to start with the camera ...

to provide collision , think to attach a jit.phys.body/ghost to your camera to interact with other body

Jit.anim.drive has a @ui_listen mode that allows you to do keyboard/mouse driven navigation. Double-clicking the jit.anim.drive lets you edit the controls dictionary. Hook jit.anim.drive @ui_listen 1 to your jit.gl.camera and you have FPS camera.

one way to do this is to use two jit.anim.nodes. the first anim.node is controlled by a anim.drive (which receives key and mouse input), and is bound to your gl.camera. the second anim.node is parented to the first, and controls a kinematic rigid body (jit.phys.body @kinematic 1).

this will sync the camera with a rigid body, and cause other rigid bodies to "bounce" off the camera, as well as allow you to retrieve and process collision information from the phys.body.

if you don't want objects to "bounce" off the camera, you can instead use a phys.ghost.

to resume the last patch you posted robert,
assume that the spheres represent static walls,

how can we ensure that the camera is constrained in its movement, it does not go through walls?

@Andrew : actually, it is not a fps camera, because the rotation is calculated on a mouse speed basis, as oppposed to a real fps where it is calculated on distance of current mouse location relatively to a fixed center location. So you can continually turn without haivng to constantly move the mouse, and you don't have that effect where you spin 81225° all of a sudden because you gave a little hiccup to your mouse :p

@touk: you have to handle the logic yourself, based on the collision dictionary.
the anim_reset message to anim.drive will cancel all currently executing animations.

another technique is to translate the output of anim.drive into forces for a dynamic phys.body, and link the gl.camera to the phys.body (instead of the other way around).

lots of options, but no ready-made solution (this is max after all).

@vichug: check out the following example patch (hit the escape key to enable mouse interaction)
