imageAtomicMax

Name

imageAtomicMax — atomically compute the maximum of a value with an existing value in memory, store that value and return the original value

Declaration

uint imageAtomicMax( gimage2D image,
  ivec2 P,
  uint data);
 
uint imageAtomicMax( gimage3D image,
  ivec3 P,
  uint data);
 
uint imageAtomicMax( gimageCube image,
  ivec3 P,
  uint data);
 
uint imageAtomicMax( gimageBuffer image,
  int P,
  uint data);
 
uint imageAtomicMax( gimage2DArray image,
  ivec3 P,
  uint data);
 
uint imageAtomicMax( gimageCubeArray image,
  ivec3 P,
  uint data);
 
int imageAtomicMax( gimage2D image,
  ivec2 P,
  int data);
 
int imageAtomicMax( gimage3D image,
  ivec3 P,
  int data);
 
int imageAtomicMax( gimageCube image,
  ivec3 P,
  int data);
 
int imageAtomicMax( gimageBuffer image,
  int P,
  int data);
 
int imageAtomicMax( gimage2DArray image,
  ivec3 P,
  int data);
 
int imageAtomicMax( gimageCubeArray image,
  ivec3 P,
  int data);
 

Parameters

image

Specify the image unit into which to store data.

P

Specify the coordinate at which to store the data.

data

Specifies the data of which to take the maximum with that stored in the image.

Description

imageAtomicMax atomically computes a new value by finding the maximum of the value of data and the contents of the texel at coordinate P in the image bound to uint image, stores that value into the image and returns the original value.
