OpenGL shader conversion

Hi everybody, I am working on a project that involves both rasterization and computation. Right now I have a shader that contains this declaration:

layout (location = 0) out vec4 FragColor;

layout (binding = 0) uniform sampler3D VolumeTexture[MIPLEVELS];
uniform mat4 ModelViewProjectionInverse;
uniform float VolumeDim;

and I was wondering what would these elements correspond into an openCL kernel. Do I need to perform any conversion or can I just use them in the same way I do in the shader:

vec4 world0 = Scale * ModelViewProjectionInverse * ndc0;
vec4 color = texture(VolumeTexture[currentLevel], texCoords);
FragColor = color;

I initialise them in this way:

glUniform1i(glGetUniformLocation(volumeRenderShader.ProgramId(), "VolumeTexture"), 0);
glUniformMatrix4fv(glGetUniformLocation(volumeRenderShader.ProgramId(), "ModelViewProjectionInverse"), 1, GL_TRUE, glm::value_ptr(glmTrans));
glUniform1f(glGetUniformLocation(volumeRenderShader.ProgramId(), "VolumeDim"), volumeDimensions);

for (int i = 0; i < MIPLEVELS; ++i){
	glActiveTexture(GL_TEXTURE0 + i);
	glBindTexture(GL_TEXTURE_3D, volumeTexture[i]);
