Set Fov and Set Fog!

[Gilmer]

Hello, im with the following doubt, in editor, in main properties, i can set the camera fov. But when i make the program in c++, has none command that i can are setting the fov. I searched in wiki and in the forum, but i not found nothing. How i can make this? The same problem occurs with the fog, i dont found any commando for this..

I believe camera FOV is just CameraZoom... not sure, would have to play around with it... and Fog is SetDistanceFog

Thanks Macklebee,

 

The Fog is really what I was needing, but I think it would be to CameraRange the FOV, would not it?

No, FOV is set using CameraZoom

[Gilmer]

i think is not, or i doing wrong..hehehe

for sample, in editor, i set the FOV to "115", but if i use the CameraZoom, what value which i need set? I put "CameraZoom(camera,115)", it show a zoom very long, but if i put "CameraZoom(camera,-115)", the image is inverted.

You are doing it wrong. According to Josh: The default FOV is 90 degrees, meaning you have a width of view that sees 90 degrees. Zoom zooms in, so zoom=2.4 should give a 45 degree FOV. Then the zoom for any FOV can be calculated as follows:

 

zoom=1.0/Tan(fov/2.0)

 

so a FOV of 115 would be CameraZoom(camera, 0.637)

With some searches, i found in the old forum, the following formule:

 

fov = 115;
zoom = 1.0/tan(fov/2.0);

 

but, no documentation wiki, dont have nothing talking about this...and is this which is working. I use this with the CameraZoom.

hehe, i post in a minute after you

but thanks all

That is weird because I cannot get that formula that you both wrote to work. Instead, I found this formula work:

 

flt zoom=0.0;
flt fov=90;
zoom = 1.0 / tan(fov*3.14159265/360);

 

I tried this because I modified a formula I found here to work with the camera zoom.

Like macklebee mentioned, the default FOV is 90 degrees. The other formula says 45 degrees is the default and multiplying that with PIE then dividing that with 180 will give 1.000. I basically took that and made 180=360 because 360/4=90 whereas 180/4=45. It makes sense there, but I cannot figure out why you guys are getting your formula to work and I cannot. Anyway, at least I found this formula to work.
