The project is a rework of the Accidental-Noise Josua Tippetts' C++ library in OpenCL. ANL-OPENCL will be used in a Java application via the Aparapi library at a later stage. The C code in src/main/cpp can be compiled into a OpenCL kernel and to be used to generate random noise like in the original Accidental-Noise library. There are tests for both the C and OpenCL kernels in src/test/cpp.

There are examples for each noise function in src/test/cpp.

#include <noise_gen.h>
#include <kernel.h>

kernel void combineRGBA_simpleBillow(
global float3 *input,
global float4 *output
) {
	int id0 = get_global_id(0);
	kiss09_state srnd;
	kiss09_seed(&srnd, 200);

	input[id0] = scaleDomain(input[id0], 5.0f);

	float bm = simpleBillow3(input[id0], value_noise3D, 200, linearInterp, random_kiss09, &srnd, 1, 0.125, true);
	float r = bm * 0.5 + 0.5;

	bm = simpleBillow3(input[id0], value_noise3D, 2000, linearInterp, random_kiss09, &srnd, 1, 0.125, true);
	float g = bm * 0.5 + 0.5;

	bm = simpleBillow3(input[id0], value_noise3D, 4000, linearInterp, random_kiss09, &srnd, 1, 0.125, true);
	float b = bm * 0.5 + 0.5;

	output[id0] = combineRGBA(r, g, b, 1.0);
}

#include <noise_gen.h>
#include <kernel.h>

REAL f[] = { 10, 5, 2.5, 1.25 };
REAL disp[] = { 100, 50, 25, 10 };

kernel void cellular_function3D_distEuclid(
global vector3 *input,
global REAL *output
) {
	int id0 = get_global_id(0);
	output[id0] = cellular_function3D(input[id0], 200, f, disp, distEuclid3);
}

All noise functions and utilities functions are available for the dimensions

• 2D and vector2 type,
• 3D and vector3 type,
• 4D and vector4 type,
• 6D and vector8 type.

The code can be used for both 32-bit and 64-bit floating-point numbers using the precompiler flag ANLOPENCL_USE_DOUBLE and the types REAL, vector2, vector3, vector4 and vector8. Although, it makes little to no difference using 64-bit floating-point to generate the noise for the end result.

Bundles the bstatcomp/RandomCL for generating random numbers in the OpenCL kernel.

Using the clang vector extension it is possible to use the same code in a C/C++ program or in a OpenCL kernel. That enables me to test the code via Google-Test framework before it is used in a OpenCL kernel. The precompiler flag ANLOPENCL_USE_OPENCL is set if the code is compiled for a OpenCL kernel.

The ANL-OPENCL code can be bundled and pre-build as a OpenCL library.
