There is a interactive online website you can check it self, its very funny but you

need a browser with WebGL support -> Firefox.

The basic is a 360° sphere panorama picture. (

Can someone tell me how i can make this "Little Planets" in gen?

Here is the GLSL shader code from the website(you can find this in the left top, press +):

_________________________________________________________________________

vec2 pnt = (v_texcoord - .5) * vec2(scale, scale * aspect);

float x2y2 = pnt.x * pnt.x + pnt.y * pnt.y;

vec3 sphere_pnt = vec3(2. * pnt, x2y2 - 1.) / (x2y2 + 1.);

float lon = atan(sphere_pnt.y, sphere_pnt.x);

gl_FragColor = texture2D(texture, vec2(lon, lat) / rads);

(Sorry if my english not good, i am better in german)

Many thanks for the support and have a nice day
