Is this possible? Alternatively, I'm familiar with Photoshops ability to stitch together photos into one larger image, like with panoramas. What I'd like to do is take a spherical object like a soccer ball, globe, etc, and make a 3D model of it using photogrammetry. What is the best way to UV unwrap a sphere? Need Help!

But, in general, one of the main points of using some kind of overinflated cube for a sphere is that you can easily uv map it to six square images -- each face of the original cube corresponds to one square image, and opengl has support for cubemapped textures So I am not quite sure what a "voronoi map texture" is. I thought it would be possible to UV unwrap the sphere in such a way as to get an identical result to the sphere projection, but that doesn't seem to be the case. For example it is far easier to track surface features on the 3D sphere or 2D plane. I’ve tried a UV sphere, Icosphere and wrapping a plane around. You could even ray project the cube into a sphere to make certain it's properly spherical. basically its mapped like a cube is, so in order to do an unwrap you first have to start with the uv map as one continuous mesh, thats why you need to flat map it first. A perfectly unwrapped sphere sans exponentially spaced UVs which aren't possible unless you tweak the map afterwards or modify the object's geometry. We chose Blensor (Gschwandtner et al. I think dealing with textures and uvs on a cube is going to be much friendlier to work with than a sphere. adjust the camera height until the plane occupies the entire render area exactly (or until it will exactly match the Feb 4, 2014 · Is there a way to automatically unwrap my character?
