softbody texture on to mesh

[stephanschulz]

thanks for the great add-on.

is it possible to apply a texture to the bunny in the SoftBodyMeshExample?
it would be great to hear your advice on how to achieve that.

thanks, stephan

The stanford bunny doesn't have any texture coords since the model was created via scanning. You could bring it into Blender and try some of the texturing tools.

ok. thx.

what about the penguin in the OF sample 3DModelLoaderExample.

I used the penguin.ply and the penguin.jpg
loaded both in and use

in setup

    texture.load("penguin.jpg");
    texture.getTexture().setTextureWrap( GL_REPEAT, GL_REPEAT );
    mesh.load("penguin.ply");

in draw

     texture.getTexture().bind();
     bunnies[i]->draw();
     texture.getTexture().unbind();

but a model never appears, and the app starts hanging when pressing key == 'b'

???

A lot of 3D models use 0 -> 1 texture coordinates. So try calling

ofDisableArbTex();
texture.load("penguin.jpg");
ofEnableArbTex();

And after the mesh.load call, print out the number of tex coords on the mesh to make sure it has texture information.

Thanks.

Still no luck. Maybe you can take a look?
I put together my OF 0.10 copy of your example.

https://www.dropbox.com/s/tsfwj4pxa45l6gu/SoftBodyMeshExample.zip?dl=0

    ofDisableArbTex();
    texture.load("penguin.jpg");
    ofEnableArbTex();

    mesh.load("penguin.ply");
    ofLog()<<"mesh.getNumTexCoords() "<<mesh.getNumTexCoords();
    ofLog()<<"mesh.getNumIndice() "<<mesh.getNumIndices();

[notice ] mesh.getNumTexCoords() 11486
[notice ] mesh.getNumIndice() 21348

Hi Stephen, I took a quick look at the project and I think it’s hanging because the penguin model has a lot more indices and bullet does much better with more simple meshes. I loaded the bunny and the ‘b’ button worked as expected. If you are able to simplify the penguin model in Blender or another 3D program and export it, that might help. You could try to just draw the penguin mesh with the texture around it, to determine if the texture is working properly. I don’t have access to OF 0.1 right now. I ran it in 0.93 and it printed out zero tex coords, so I was unable to see the texture. Let me know if you have any other questions. Best, Nick

Thanks again.

I went ahead and made a OF 0.9.8 project.

You are right that the penguin has 4 times more vertices.
So I tried the squirrel. It's hard to tell if it texture maps ok, since it is super small in the app.

I guess I will have to find a ok sized model + it's texture.
Does the texture need to have a specific size, or would any image work?

If you wanted to use the squirrel, you could load it and then scale all of the vertices up Typed on a tiny keyboard
