vec3 extra

Header: cglm/vec3-ext.h

There are some functions are in called in extra header. These are called extra because they are not used like other functions in vec3.h in the future some of these functions ma be moved to vec3 header.

void glm_vec3_mulv(vec3 a, vec3 b, vec3 d)

multiplies individual items

Parameters:
[in] a vec1
[in] b vec2
[out] d destination (v1[0] * v2[0], v1[1] * v2[1], v1[2] * v2[2])
void glm_vec3_broadcast(float val, vec3 d)

fill a vector with specified value

Parameters:
[in] val value
[out] dest destination
bool glm_vec3_eq(vec3 v, float val)

check if vector is equal to value (without epsilon)

Parameters:
[in] v vector
[in] val value
bool glm_vec3_eq_eps(vec3 v, float val)

check if vector is equal to value (with epsilon)

Parameters:
[in] v vector
[in] val value
bool glm_vec3_eq_all(vec3 v)

check if vectors members are equal (without epsilon)

Parameters:
[in] v vector
bool glm_vec3_eqv(vec3 v1, vec3 v2)

check if vector is equal to another (without epsilon) vector

Parameters:
[in] vec vector 1
[in] vec vector 2
bool glm_vec3_eqv_eps(vec3 v1, vec3 v2)

check if vector is equal to another (with epsilon)

Parameters:
[in] v1 vector1
[in] v2 vector2
float glm_vec3_max(vec3 v)

max value of vector

Parameters:
[in] v vector
float glm_vec3_min(vec3 v)
min value of vector
Parameters:
[in] v vector
bool glm_vec3_isnan(vec3 v)
check if one of items is NaN (not a number)
you should only use this in DEBUG mode or very critical asserts
Parameters:
[in] v vector
bool glm_vec3_isinf(vec3 v)
check if one of items is INFINITY
you should only use this in DEBUG mode or very critical asserts
Parameters:
[in] v vector
bool glm_vec3_isvalid(vec3 v)
check if all items are valid number
you should only use this in DEBUG mode or very critical asserts
Parameters:
[in] v vector
void glm_vec3_sign(vec3 v, vec3 dest)

get sign of 32 bit float as +1, -1, 0

Parameters:
[in] v vector
[out] dest sign vector (only keeps signs as -1, 0, -1)
void glm_vec3_sqrt(vec3 v, vec3 dest)

square root of each vector item

Parameters:
[in] v vector
[out] dest destination vector (sqrt(v))
