* Add comparison operator for use from unit tests. Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * First version of FastNoise benchmarks. Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * Simplified unit tests and added initial benchmarks. Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * Add GetValue vs GetValues unit test. Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * Moved Gradient test code into helper files for use from FastNoise. Also added benchmarks for each type of FastNoise so that we can have some comparative values handy. Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com> * Specialization for GetValues(). Signed-off-by: Mike Balfour <82224783+mbalfour-amzn@users.noreply.github.com>
