Hi there and sorry if this has been answered before. I really looked on posts and solutions, but i am still so new to porcessing. I just signed in to ask for help. I followed this great tutorial as a starting point: (the famous Perlin/Terrain generation): [image] 3D Terrain Generation wit…

Good afternoon. [image] Tiemen: Draw a simple, rectangular grid using two separate for loops (without PShape). So one draws the x-axis, the other the y-axis. Add a color transition to one axis Replace the drawing technique of step 1 with PShape Draw a rectangular grid using a nested for loop ? …

Hello @crv74 , Try applying the stroke before the inner loop; y is rows so you will be changing the color for each row. [image] Related topic: https://discourse.processing.org/t/generative-terrain-customization/39396/2 :)

Hi glv, i readed that post, and several more, but i must be dumb or something… If i put the stroke in any place out of where i showed, i get either an error or a green BG only… If you can hint me a bit more, i’ll appreciate it. Because this is driving me nuts. Not working for me: for(int y = 0…

The following piece of code: [image] crv74: if (cl > 240); cl = 35; is equivalent to: if (cl > 240) { //nothing happens! :( } cl = 35; Does solving that bring you a step closer?

Thanks, but no. And my head is about to explode… I leave it untill tomorrow. Really appreciate it but i can’t figure it out. Carles p.s. I assume that since i started with this tutorial but i know nearly nothing of Processing i’m missing a lot of basics that could help me.

No worries, that frustration is part of programming. Especially in the beginning. What you could try tomorrow is to simplify your problem first, and then work your way back up towards the tutorial. Take it one step at the time and gradually extends the complexity of your sketch. For instance: Dra…

Hello @crv74 , [image] crv74: And my head is about to explode… I leave it untill tomorrow. Really appreciate it but i can’t figure it out. I will often solve problems by walking away and coming back fresh. There is a Troubleshooting link on this page that specifically discussed the Semicolo…

Hello @crv74 , Another approach: size(400, 400, P3D); int rows = 21; int cols = 21; int scl = 20; int cl = 0; background(0); strokeWeight(2); noFill(); for (int y = 0; y < rows-1; y++) { beginShape(TRIANGLE_STRIP); int col = y*255/19; println(col); stroke(col); for (int x …

I have lots to learn and so few time… High IQ in here! :wink:

[image] crv74: High IQ in here! :wink: That’s @glv for you. He’s the prodigy that created GLV Paint .

I assume that at this point we could start tilting over the 3D space and paintin lines, right?? :wink:
