Vec4 show all
Defined in:
lib/cglm/sphere.rb,
ext/cglm/rb_cglm.c

Overview

Sphere Representation in cglm: [center.x, center.y, center.z, radius]

You could use this representation or you can convert it to Vec4 before calling any function.

Constructor Details

This class inherits a constructor from CGLM::VectorType

Instance Method Details

#contains_point?(point) ⇒ Boolean

Returns true if self contains the specified Vec3, false otherwise.

Returns:

  • (Boolean)

# File 'ext/cglm/rb_cglm_sphere.c', line 48

VALUE rb_cglm_sphere_contains_point(VALUE self, VALUE point) {
  return glm_sphere_point(VAL2VEC4(self), VAL2VEC3(point)) ? Qtrue : Qfalse;
}

#intersects_sphere?(other) ⇒ Boolean

Returns true if self intersects other, false otherwise.

  • other must be a Sphere or a Vec4 with the layout [x, y, z, radius].

Returns:

  • (Boolean)

VALUE rb_cglm_sphere_intersects_sphere(VALUE self, VALUE other) {
  return glm_sphere_sphere(VAL2VEC4(self), VAL2VEC4(other)) ? Qtrue : Qfalse;
}

#merge(other[, dest]) ⇒ dest | new Sphere

Merges two spheres (self and other) and places the result in dest. If dest is omitted, a new Sphere will be created.

Both spheres must be in the same space. For instance, if one is in world space then the other must be in world space and not in local space.

  • other must be a Sphere or a Vec4 with the layout [x, y, z, radius].

#transform(mat4[, dest]) ⇒ dest | new Sphere

Transforms this sphere to put it in the space described by mat4, and puts the result into dest. If dest is omitted, a new Sphere is created.
