Patching with Gen in this hi level is new to me, i need help.
I like this:
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. ( http://de.wikipedia.org/wiki/Kugelpanorama )
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 +):
precision mediump float;
uniform sampler2D texture;
uniform float scale, aspect, time;
uniform mat3 transform;
varying vec2 v_texcoord;
#define PI 3.141592653589793
vec2 rads = vec2(PI * 2., PI);
vec2 pnt = (v_texcoord – .5) * vec2(scale, scale * aspect);
// Project to Sphere
float x2y2 = pnt.x * pnt.x + pnt.y * pnt.y;
vec3 sphere_pnt = vec3(2. * pnt, x2y2 – 1.) / (x2y2 + 1.);
sphere_pnt *= transform;
// Convert to Spherical Coordinates
float r = length(sphere_pnt);
float lon = atan(sphere_pnt.y, sphere_pnt.x);
float lat = acos(sphere_pnt.z / r);
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
