| /** "Test 2" from CTS_EXT_gpu_shader5. Description follows |
| * |
| * Test whether indexing into an array of images using constant |
| * expressions works as expected. |
| * |
| * Category: API, |
| * Functional Test, |
| * |
| * Get the maximum size of work group in x and y direction by computing: |
| * |
| * unsigned int max_wgs_x = 0; |
| * glGetIntegeri_v(GL_MAX_COMPUTE_WORK_GROUP_SIZE, 0, &max_wgs_x); |
| * |
| * unsigned int max_wgs_y = 0; |
| * glGetIntegeri_v(GL_MAX_COMPUTE_WORK_GROUP_SIZE, 1, &max_wgs_y); |
| * |
| * Write a compute shader with an array of 4 uimage2D image handlers. |
| * The work group size should be (max_wgs_x, max_wgs_y, 1). |
| * |
| * For each of the uimage2D image handlers bind a (max_wgs_x, max_wgs_y) |
| * image texture with GL_RGBA32UI internal format. Data of the textures |
| * should be set to (1,1,1,1). |
| * |
| * In the compute shader perform operations: |
| * |
| * uvec4 texel0 = imageLoad(image[0], ivec2(gl_LocalInvocationID.x, |
| * gl_LocalInvocationID.y) ); |
| * |
| * uvec4 texel1 = imageLoad(image[1], ivec2(gl_LocalInvocationID.x, |
| * gl_LocalInvocationID.y) ); |
| * |
| * uvec4 texel2 = imageLoad(image[2], ivec2(gl_LocalInvocationID.x, |
| * gl_LocalInvocationID.y) ); |
| * |
| * uvec4 texel3 = imageLoad(image[3], ivec2(gl_LocalInvocationID.x, |
| * gl_LocalInvocationID.y) ); |
| * |
| * uvec4 addon = uvec4(gl_LocalInvocationID.x+gl_LocalInvocationID.y); |
| * |
| * imageStore(image[0], ivec2( gl_LocalInvocationID.x, |
| * gl_LocalInvocationID.y), texel0 + addon); |
| * |
| * imageStore(image[1], ivec2( gl_LocalInvocationID.x, |
| * gl_LocalInvocationID.y), texel1 + addon); |
| * |
| * imageStore(image[2], ivec2( gl_LocalInvocationID.x, |
| * gl_LocalInvocationID.y), texel2 + addon); |
| * |
| * imageStore(image[3], ivec2( gl_LocalInvocationID.x, |
| * gl_LocalInvocationID.y), texel3 + addon); |
| * |
| * Create a program from the above compute shader, use it |
| * and call glDispatchCompute(1, 1, 1); |
| * |
| * Read back the data from the textures corresponding to image units. |
| * |
| * The test is successful if for each texture and for each texel |
| * in the texture we get (x,y) -> (x+y+1, x+y+1, x+y+1, x+y+1). |
