NAME
max - returns the maximum of two scalars or each respective component of two vectors
SYNOPSIS
float max(float a, float b); float1 max(float1 a, float1 b); float2 max(float2 a, float2 b); float3 max(float3 a, float3 b); float4 max(float4 a, float4 b); half max(half a, half b); half1 max(half1 a, half1 b); half2 max(half2 a, half2 b); half3 max(half3 a, half3 b); half4 max(half4 a, half4 b); fixed max(fixed a, fixed b); fixed1 max(fixed1 a, fixed1 b); fixed2 max(fixed2 a, fixed2 b); fixed3 max(fixed3 a, fixed3 b); fixed4 max(fixed4 a, fixed4 b);PARAMETERS
- a
Scalar or vector.
- b
Scalar or vector.
DESCRIPTION
Returns the maximum of two same-typed scalars a and b or the respective components of two same-typed vectors a and b. The result is a three-component vector.
REFERENCE IMPLEMENTATION
max for float3 vectors could be implemented this way:
float3 max(float3 a, float3 b) { return float3(a.x > b.x ? a.x : b.x, a.y > b.y ? a.y : b.y, a.z > b.z ? a.z : b.z); }PROFILE SUPPORT
max is supported in all profiles. max is implemented as a compiler built-in.
Support in the fp20 is limited.
