Cycling84

I am using jit.bfg and its very clear how it fills a 1 dimensional matrix. However, I am trying to wrap my head around how it calculates or fills out the values for evaluating across a 2D matrix.

In particular, I am reading the tutorial 50: Procedural Texturing & Modeling and when I go to look at the sine: Periodic sinusoidal curve example I am not seeing how the sine curve translates into the grayscale picture.

Any insight would be greatly appreciated. thank you!

how-does-jit-bfg-fill-a-2d-matrix

So, still curious about this? Is there anyone who can help? I was able to generate the sine wave examples in 2D on my own without using BFG, but I can't figure out how the noise or fractal 2D images are generated. Perhaps what I'm asking for is considered proprietary by cycling74. But if its not I'd appreciate a response. I really like the images that are created with jit.bfg and if I can understand how to create them I can integrate that into my current approaches. Thanks!

this creates a 1 plane matrix thats 8 x 8 pixels

this creates a 3 plane 3 dimensional matrix.

create the following
jit.bfg 1 8 8
this creates a 1 plane matrix thats 8 x 8 pixels
jit.bfg 3 16 16 16
this creates a 3 plane 3 dimensional matrix.


Hi Andro, Thanks for the reply but this does not answer my question. I want to know HOW the matrix is filled. I already know what jit.bfg's arguments do. But I'm interested in how the jit.bfg fractal and noise generators fill at 2D space. Meaning, does jit.bfg generate coordinates in a linear sequence and fill the values in in a linear way, or does it use some sort of a spatial map etc? If you look at that tutorial 50 on procedural modeling and texturing. Look at the pictures and you will see a 1 D image of a wave on the left, and on the right a 2D image. I'm not sure how the fractal or noise waves translate or generate the image on the right. I want to try to make the image on the right using the wave on the left, but not using jit.bfg
