camera distance

malachi · Post by **malachi** » Tue May 18, 2004 1:44 am

Hello, I have a large terrain mesh and want to see accross the entire mesh, but it seems there is a clipping range built into the camera distance ..

any ideas to extend, or am i being an idiot? sorry - i am primarily a 3D artist/animator (max) determined to learn at least some basic programming..

does this also fix the 'fisheye view" that I see in the demo?

It can never fix it, that's the catch with 3D games on a 2D moniter, it can reduce it if you get the right value. I've got a cheap hack for that so I never have to fiddle with the settings; I have a GUI bar on each side of the screen that coincidently hides it quite well

i wanted to try that. but i am not yet able to work with the docu! i have never worked with such a thing like that documentation of an api or what irrlicht is.

can you give me a step by step example of to use the docu to use the setFarValue
to the camera (smgr->addCameraSceneNodeFPS(0, 0.0f, 0.0f, -1, 0, 0) ; )

Open that link...click the setFarValue() link and it will take it to the definition.

Surely it isn't that hard?

You can use the code like this to fix the "fisheye view":

Code: Select all

#define PI 3.1415926538
.
.
.
cam->setFOV(PI/2);

virtual void irr::scene::ICameraSceneNode::setFarValue ( f32 zf ) [pure virtual]

Sets the value of the far clipping plane (default: 2000.0f)

Parameters:
zf: New z far value.

ok the link gives me that result but i realy don't know how to use that exactly.

how to use setFarValue ? i want to set the farvalue to 20000.0f --
setFarValue ( 20000.0f ) ;

but how can i use the docu so that i know what to wright ? i don't want to trouble everybody with my garbage ... i whant to know how to use the docu

i found that by seraching the forum

camera->setFOV(70);
camera->setFarValue(1000);
camera->setNearValue(1.4);

so were did i get camera? i want to use smgr->addCameraSceneNodeFPS(0, 100.0f, 400.0f, -1, 0, 0); ..... if i know how to use the docu i don't ask silly question again I swear!!!!!

scene::ICameraSceneNode* camera = smgr->addCameraSceneNodeFPS(0, 100.0f, 400.0f, -1, 0, 0);

Then do:

camera->setFarValue( 20000 );

thx u fery much !

smgr->addCameraSceneNodeFPS(0, 100.0f, 400.0f, -1, 0, 0);

it is thus a shortened way of writing

scene::ICameraSceneNode* camera = smgr->addCameraSceneNodeFPS(0, 100.0f, 400.0f, -1, 0, 0);

without creating a camera or only internally creation of it so that i can't use
setFarValue( 20000 ); ( if this what a say is not true then it is unimportant)

it works and only this is important

You can create the camera without storing the pointer that's returned upon creation, but you won't be able to access it or modify any of it's values.

thats what i mean

..............
Then do:

camera->setFarValue( 20000 );[/quote]

this works great thanks!
