Rectangular Textures on a Sphere

[screenmutt]

I am looking for a way to map rectangular textures, like the ones found on this site, onto a sphere.

 

Right now they wrap in a weird way and just look... blah.

 

 

Is there a way to do this or to convert the texture?

How do you create your spheres? With BABYLON.Mesh.CreateSphere ?

[screenmutt]

Yes. That is how I created my sphere. Sorry, I should have specified.

[GameMonetize]

If this case, babylon.js generates arbitrary textures coordinates. You have many options to do what you want

- Use Blender to generate a sphere with appropriate texture coordinates

- Use texture.uOffset, vOffset, uScale, vScale to move the texture

Is there any way to change the mapping mode? Right now it wraps around instead of "pinching" like I hoped it would do.

[screenmutt]

Actually. I just decided to try importing models from blender. However, now I am running into the following problem.

 

Here is my code:

    // Load Blender    BABYLON.SceneLoader.ImportMesh("", "", "Models.babylon", scene, function(meshes, particles) {      alert('Loaded');    });

And here is the error I get

Uncaught Error: 0 babylon.1.6.0.js:1

Any thoughts?

 

The file is definitely there.

[GameMonetize]

is there any other information on the console?

could you share your code somewhere?

Here is the full console output:

Valid manifest file not found. Scene & textures will be loaded directly from the web server. babylon.1.6.0.js:20event.returnValue is deprecated. Please use the standard event.preventDefault() instead. jquery.js:5374Uncaught Error: 0 babylon.1.6.0.js:1request.onreadystatechange babylon.1.6.0.js:1

Here is a link to the project.

Sorry about it all being in the same file. This is really just an experiment and I am doing a lot of re-factoring as I go, meaning 1 file is the easiest to work with. It won't end up that way though!

Ok guys! I figured out the problem.

 

I used that totally awesome BABYLON VIEWER app and the files worked perfectly. So I tried simplifying what was going on with my project.

 

Turns out I am not able to load .babylon files locally. Once I uploaded it to a server it worked perfectly. Thanks guys!

In your ImportMesh the 'name' and the 'path' are empty. This is may be the error.

BABYLON.SceneLoader.ImportMesh("Your name mesh here", "Your path here", "Models.babylon", scene, function(meshes, particles) {    alert('Loaded');});

OMAGAD OMAGAD It's my app !! Thank you <3

 

More seriously, you won't be able to load babylon files locally. You have to get through a local server. In Babylon, all files are retrieved using AJAX requests, and for some security reasons, you cannot request a local file using AJAX.

Does anybody know the right vOffset, vScale, uOffset, uScale to wrap a mercator projection off the earth around a sphere?

I have been experimenting, but I don't seem to get it right

 

I found out myself:

The best way to wrap a rectangle mercator projection around a sphere is to create a image of 1024 by 512 or at least in these proportions. Then it wraps around beautifully.

So you need to have image that is twice as high as wide.
