gimage2D image, |
ivec2 P); |
gvec4 imageLoad(

gimage3D image, |
ivec3 P); |
gvec4 imageLoad(

gimageCube image, |
ivec3 P); |
gvec4 imageLoad(
|
gimageBuffer image, |
int P); |

|
gimage2DArray image, |
ivec3 P); |
gvec4 imageLoad(

ivec3 P); |
image
Specify the image unit from which to load a texel.
P
Specify the coordinate from which to load the texel.
imageLoad loads the texel at the coordinate P from the image
unit image. When image and P identify
a valid texel, the bits used to represent the selected texel in memory are converted to a vec4, ivec4, or uvec4
in the manner described in the OpenGL ES Specification and returned.
