Apply texture to a mesh on all 3 sides

I would recommend getting some/all of the existing voxel add-ons from the Asset Store and see how they did it. VoxelForm is my favorite.

I don't have the money to buy any voxel add-ons, and im pretty sure someone out there knows how to do this. Does anyone have any sample code, or a website that explains how to apply a texture onto a mesh from all 3 sides.

O$$anonymous$$, after doing further thinking, I think I figured out how to do something simaler to triplanar textureing. First off, I create a 3 UVs for all 3 sides by doing this:

 uvsx = new Vector2[mesh.vertices.length];
 for (var i=0; i < uvsx.Length; i+=1) {
 uvsx[i] = Vector2(mesh.vertices[i].y,mesh.vertices[i].z);
 }
 uvsy = new Vector2[mesh.vertices.length];
 for (var i=0; i < uvsy.Length; i+=1) {
 uvsy[i] = Vector2(mesh.vertices[i].z,mesh.vertices[i].x);
 }
 uvsz = new Vector2[mesh.vertices.length];
 for (var i=0; i < uvsz.Length; i+=1) {
 uvsz[i] = Vector2(mesh.vertices[i].x,mesh.vertices[i].y);
 }

All I need to do now is blend them together as one. Unfortunately, I don't know how. So does anyone know how to blend these 3 UV together?

How about looking at some open source voxel engines and seeing how they did it?

O$$anonymous$$, I have looked all over the internet, and I have found a few shaders. But I have no idea what I would use a shader for. Also, when I transfer them into my game, they always give parsing error's that I don't know how to fix because I usually work with java script. Does anyone now how to finish up the code I posted above, or at least show me a website with a working triplanar texturing code?
