+
+**Definition of sphere:**
+
+Sphere Representation in cglm is *vec4*: **[center.x, center.y, center.z, radii]**
+
+You can call any vec3 function by pasing sphere. Because first three elements
+defines center of sphere.

+.. c:function:: float  glm_sphere_radii(vec4 s)
+
+    | helper for getting sphere radius
+
+    Parameters:
+      | *[in]*  **s**   sphere
+
+    Returns:
+       returns radii
+
+.. c:function:: void  glm_sphere_transform(vec4 s, mat4 m, vec4 dest)
+
+    | apply transform to sphere, it is just wrapper for glm_mat4_mulv3
+
+    Parameters:
+      | *[in]*  **s**    sphere
+      | *[in]*  **m**    transform matrix
+      | *[out]* **dest** transformed sphere
+
+.. c:function:: void  glm_sphere_merge(vec4 s1, vec4 s2, vec4 dest)
+
+    | merges two spheres and creates a new one
+
+    two sphere must be in same space, for instance if one in world space then
+    the other must be in world space too, not in local space.
+
+    Parameters:
+      | *[in]*  **s1**      sphere 1
+      | *[in]*  **s2**      sphere 2
+      | *[out]* **dest**    merged/extended sphere
+
+.. c:function:: bool  glm_sphere_sphere(vec4 s1, vec4 s2)
+
+    | check if two sphere intersects
+
+    Parameters:
+      | *[in]*  **s1**      sphere
+      | *[in]*  **s2**      other sphere
