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.
