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

-
float glm_sphere_radii(vec4 s)
- helper for getting sphere radius
- Parameters:
- [in] s sphere
- Returns:
returns radii
-
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
-
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
-
bool glm_sphere_sphere(vec4 s1, vec4 s2)
- check if two sphere intersects
- Parameters:
- [in] s1 sphere[in] s2 other sphere
-
bool glm_sphere_point(vec4 s, vec3 point)
- check if sphere intersects with point
- Parameters:
- [in] s sphere[in] point point
