3D Panorama View with 2D assets.
Hi @ll,
i hope this is the right forum, because it is a camera question.
I want to create a 3D panorama view with pre rendered 2D pictures.
I modeled a 3D enviroment and take picture in a cube.
So I got 6 pictures: Front, Back, Left, Right, Top, Bottom.
Now I build a cube and put the picture on it. And it works. Now when I am moving the cube around (or the camera) in the edges of the cube the pictures stretch and it looks unrealistic.
So I was think maybe a Sphere will help me. I generated a (hexa) Sphere and put again my 6 sides on it.
Now my problem is I have a "fish-eye" effect. I am new to 3D at all, and I read about the camera it can be "perspective projection" or "othogal projection" I am using the first one.
Is there a way to setting up the camera to minimize the "fish-eye" effect. Or is there another way to make a panorama 3D view?
Please let me know if I am wrong here, and may be you can help me find the right forum :/
greetings

hi,
just apply uvw mapping for the cube and give the parameters to face . so it clears ur img strch.!

CeeJay, you have a fish eye effect because the textures are on sphere not because of the camera. From what I know virtual cameras from 3d softwares do not have fish eye effects.
But my knowledge may be out of date
can you post your results, this will clear things up a bit.

I am really new to 3D, when you talk from UVW maps, are there same same as UV Maps? And what do they do? I am guessing that are the infos you need where to put the textures in a 3D room? I dont get how could this change the stretch effect?
And when I am using a cube, and there is a horizontal line on to side of the cube. When I am eye level 0 on the same like the line, there is "just" the stretch effect in the corners but when i look up and down, the line will bend like a V or ^ this effect is unwanted to :/
and i know it works somehow, i have seen a on "cube map genereator" where you can but the six sides on a sphere and the programm will show a box around the sphere witch avoids somehow the bend and the stretch effect.
I just want to understand how it works, I am working on Hardware not any 3D programm so i cannot give some exapmle screenshots, sry :/
