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.

Functions:

float glm_sphere_radii(vec4 s)¶

helper for getting sphere radius

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

bool glm_sphere_point(vec4 s, vec3 point)¶

check if sphere intersects with point
