java - Fractal noise terrain generating strange artefact lines -

-

I have a perline fractal noise pattern that generates a remarkable area. The problem I am facing is some strange lines going in both the X and Z directions, I am thinking that this would have to do with the fractal generation, but as I made it 2D pictures, I do not have any artifacts Sees

Partition is divided into parts of the region, which alternately divides into tiles, which is a shape based on resolution.

Size + (posx * (map size), z * tileSize + (posZ * (mapSize), 25000,0.5,16); Fractal function: 

  Flat fractal (int x, int y, float grid subs, float gain, int octaves) {float total = 0; Float Freak = 1.0 / GridSubes; Float amp = gain; For (int f = 0; f & lt; octaves; f ++) {total + = noise (x * freq, y * freq) * amp; Freq * = 2.0; Amp * = Benefits; } Total Return; }  Edit:  I have not really given a good answer why this is happening but one possibility is that I have something for the upper position There are strange values ​​(though I should not be). 
 
 I am still trying to find ways to render my circuits without their circuitry. There are fewer artifacts with some tests and as far as I know how simple leagues work in processing, I can update it if I can not find any way around it. 
 
 If someone is still an easy way to reduce the effect on the scenario or just a good suggestion, please post below :)

My first impulse is to ask why are you manually computing octaves instead of using noise deltates?

If you want more total amplitude than your noise, increase noise production by some scalers> 1 If you want more detail to be present within that dimension, Then increase the noise.

The artifacts you are seeing are an essential part of the fact that you are using octagonal aligned perlin noise generated from the same seed, not just stacking it with any lube and above it, something Running behind implementation-specific interpolation scenes. Either try to make Perlin noise yourself or use the Pelean noise made either, do not try to do both.

Editing Python Class in Shell and SQLAlchemy -

I am working on the terminal on a shell script after this tutorial SQLAlchemy tutorial. I need to type gt; & Gt; & Gt; Sqlalchemy import column, integer, string & gt; & Gt; & Gt; Class user (base): __tablename__ = 'users' id = column (integer, primary_key = true) name = column (string) absolute name = column (string) password = column (string) def __repr __ (self): return "& lt ; User (name = '% s', absolute name = '% s', password = '% s') & gt; "% (Self.name, self.fullname, self.password) After the problem I have typed the password = column (string) I hit twice and changed .... >> I then took everything back but then an error was thrown because the class already exists ... I am not completely sure how to fix it. How do I open that slip in the shell script and edit it (Add DF to DRR) The error thrown below: / user / giripeters / TFSQLLX / Lib / python2.7 / site-packages / sqlalchemy / ext / decla...

lua - HowTo create a fuel bar -

I would like to create a fuel bar (empty with full tank). When the user touches the screen, the fuel once Dairejh these is my code: lifeBar = display.newImage ( "fuel_bar1.png") lifeBar.anchorX = 0 lifeboats. ======================== Lifetime Y = 37 screens Group: The Insert function (called Laifbar) However, I fuel Kansmoshn (equivalent to "pressed" variable to reduce the fuel tank "true") Have used. When pressed == is true, it means that the user is touching the screen: processed (fuel) processed () if life & gt; 0 and pressed == true remains = life - life 1 Life = life =. Wide-1 remains Value.text = string.format ("% d", life) End of this This function is active as the entrance event: runtime: addEventListener ( "Antrfrem" fuel Snsadna) it is very well, but my question is: pressed variable each time 5 seconds (once = = True) How is it possible to reduce the vitality width? I tried to add it to my touch even...
