If I try to compile the OpenGLExample I get this error message
/usr/lib/mono/xbuild/14.0/bin/Microsoft.Common.targets: Error: Tool exited with code: 1. Output: Error: Invalid ResX input.
Position: Line 123, Column 5.
Inner exception: Could not find a part of the path "/home/markus/Projects/SharpNoise/Examples/OpenGLExample/resources/normals.frag".
(OpenGLExample)
Don't know what this means or how I can solve this.
Hello,
I have been looking through the documentation, and I am wondering whether there is any built-in functionality to normalize/map all values inside a noise map instance to a certain fixed range (such as [0.0, 1.0]
) based on the minimum and maximum?
Of course, implementing this yourself isn't a big deal, but since I have been doing it in multiple projects again and again I feel like this could be a nice thing to implement as a library feature. What is your opinion on this? (I would be willing to add such functionality if its a desired feature)
I was getting weird results from the Curve module so I went digging through the code.
This is the return statement from the CubicInterp function in the original libnoise:
return p * a * a * a + q * a * a + r * a + s;
And this is the return statement from the Cubic method of NoiseMath in SharpNoise:
return (p * a * a * a) + (q * a * a * a) + (r * a) + s;
It seems q
is being multiplied by a
one too many times. Removing the extra multiplication fixed the issues I was having.
In test SharpNoise.Tests\GraniteTextureTest.cs, in GraniteTexture_SphericalRender
test (the last one), the output file created in:
bitmap.Save(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "test.bmp"), System.Drawing.Imaging.ImageFormat.Bmp);
Should be removed after the test end.
Or file created into temp directory.
I can create a new nuget package, which will create confusion. Any chance of getting a new release pushed to nuget?
You currently have the permutation table defined as:
private static readonly short[] P =
{
151,160,137,91,90,15, ...
};
If you instead randomly select those values you should get random simplex noise.
Alternately you can shuffle the table while expanding the permutations, see this implementation for a seeded simplex: https://github.com/everbytes/LibNoise/blob/master/src/LibNoise.NET35/Primitive/ImprovedPerlin.cs
Using var source = module.SourceModules[0];
will never thrown the expected exception (NoModuleException
) as Module class constructor will always initialize source array properly:
if (sourceModuleCount > 0)
sourceModules = new Module[sourceModuleCount];
else
sourceModules = emptyModulesArray;
(and also, exception is not even declared as throw-able, AFAIK)
Hello , first say thanks for this nice library is pretty interesting and useful, im doing a visual implementation for a programming enviroment call vvvv gamma,i get all the modules work except the spheres, is implemented in the library or just on the way?
Thanks
For an easy start it would be nice if you could add a more simple example without a GUI. Just how to set up a noise and save an image for example.
I would really appreciate it, if you where adding Opensimplex noise as module because Perlin noise has some ugly artifacts and Simplex has some patent issues.
I'm not sure if there is anything in the library that couldn't work with .Net Core. especially now that version 2.0 is available. Is it just a matter of adding new targets to the nupkg?
