Name

imageAtomicAdd — atomically add a value to an existing value in memory and return the original value

Declaration

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

Parameters

image

Specify the image unit into which to add data.

P

Specify the coordinate at which to add the data.

data

Specifies the data to add into the image.

Description

imageAtomicAdd atomically computes a new value by adding the value of data to 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.
