Declaration
gvec4 imageLoad( | gimage1D image, |
| | int P); |
gvec4 imageLoad( | gimage2D image, |
| | ivec2 P); |
gvec4 imageLoad( | gimage3D image, |
| | ivec3 P); |
gvec4 imageLoad( | gimage2DRect image, |
| | ivec2 P); |
gvec4 imageLoad( | gimageCube image, |
| | ivec3 P); |
gvec4 imageLoad( | gbufferImage image, |
| | int P); |
gvec4 imageLoad( | gimage1DArray image, |
| | ivec2 P); |
gvec4 imageLoad( | gimage2DArray image, |
| | ivec3 P); |
gvec4 imageLoad( | gimageCubeArray image, |
| | ivec3 P); |
gvec4 imageLoad( | gimage2DMS image, |
| | ivec2 P, |
| | int sample); |
gvec4 imageLoad( | gimage2DMSArray image, |
| | ivec3 P, |
| | int sample); |
Parameters
-
image -
Specify the image unit from which to load a texel.
-
P -
Specify the coordinate from which to load the texel.
-
sample -
When present, specifies the sample within the image to load
Description
imageLoad loads the texel at the coordinate P from the image unit image. For multi-sample loads, the sample number is given by sample. When image, P, sample 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 Specification and returned.
