LYGIA Shader Library

lengthSq (lygia/math/lengthSq)

Squared length

Use:

<vec4|vec3|vec2> lengthSq(<vec4|vec3|vec2> v)

Check it on Github


#ifndef FNC_LENGTHSQ
#define FNC_LENGTHSQ

float lengthSq(in vec2 v) { return dot(v, v); }
float lengthSq(in vec3 v) { return dot(v, v); }
float lengthSq(in vec4 v) { return dot(v, v); }

#endif

Use:

<float2|float3|float4> lengthSq(<float2|float3|float4> v)

Check it on Github


#ifndef FNC_LENGTHSQ
#define FNC_LENGTHSQ

float lengthSq(in float2 v) { return dot(v, v); }
float lengthSq(in float3 v) { return dot(v, v); }
float lengthSq(in float4 v) { return dot(v, v); }

#endif

fn lengthSq2(v: vec2f) -> f32 { return dot(v, v); }
fn lengthSq3(v: vec3f) -> f32 { return dot(v, v); }
fn lengthSq4(v: vec4f) -> f32 { return dot(v, v); }

Dependencies:

Use:

<float2|float3|float4> lengthSq(<float2|float3|float4> v)
