Functions

safeNormalize

Normalize a vector, protecting against overflow in the intermediate computations.

Declaration(s):

 
 vec2 safeNormalize(vec2 v);
 vec3 safeNormalize(vec3 v);
 vec4 safeNormalize(vec4 v);
    

safeLength

Compute the length of a vector, protecting against overflow in the intermediate computations.

Declaration(s):

 
 float safeLength(vec2 v);
 float safeLength(vec3 v);
 float safeLength(vec4 v);
    

safeDistance

Compute the distance between two points, protecting against overflow in the intermediate computations.

Declaration(s):

 
 float safeDistance(vec2 p0, vec2 p1);
 float safeDistance(vec3 p0, vec3 p1);
 float safeDistance(vec4 p0, vec4 p1);
    

safeAtan

Compute the atan between x and y. Unlike regular atan, this function provides results for x = 0.0.

Declaration(s):

 float safeAtan(float y, float x);
