Where to start with voxel engine?

阅读更多关于 Where to start with voxel engine?

问题 I have been working on a voxel game for some time now, but all that I have really accomplished was the main menu and an Item system. Now its time to make the voxel engine. I have been searching for a while now to find some tutorials or an ebook that will teach me such, but the best i could find were someones tutorials in c++, but I am making mine in Java. I have dabbled in c++ and c# in the past but it was too difficult to translate i.e. it relied on a class that java doesn't have. What I

What's faster for 3D? Perlin or Simplex noise?

问题 Okay, there are a lot of comparisons between Perlin and Simplex noise to be found on the web. But I really couldn't find one where there was a simple processing time comparison between both for three dimensions, which is what I am mostly interested in. I've read that popular PDF (and even understood most of it - yay!) but I cannot answer the simple question: Which one is faster for 3D, assuming an optimal implementation? This stackoverflow question answer suggests that Simplex is a pretty

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . I want to create a terrain-like 3D noise generator and after doing some research I came to the conclusion that Simplex Noise is by far the best type of noise to do this. I find the name quite misleading though as I have a lot of trouble finding resources on the subject and the resources I find are often not well

I've read that popular PDF (and even understood most of it - yay!) but I cannot answer the simple question: Which one is faster for 3D, assuming an optimal implementation? This stackoverflow question answer suggests that Simplex is a pretty clear winner for my case. Of course, there are other resources claiming the exact opposite. However, the

Simplex noise vs Perlin noise

阅读更多关于 Simplex noise vs Perlin noise

问题 I would like to know why Perlin noise is still so popular today after Simplex came out. Simplex noise was made by Ken Perlin himself and it was suppose to take over his old algorithm which was slow for higher dimensions and with better quality (no visible artifacts). Simplex noise came out in 2001 and over those 10 years I've only seen people talk of Perlin noise when it comes to generating heightmaps for terrains, creating procedural textures, et cetera. Could anyone help me out, is there

I want to create a terrain-like 3D noise generator and after doing some research I came to the conclusion that Simplex Noise is by far the best type of noise to do this. I find the name quite misleading though as I have a lot of trouble finding resources on the subject and the resources I find are often not well written. What I am basically looking for is a good resource/tutorial explaining step by step how simplex noise works, and explains how to implement that into a program. I am not looking for resources explaining how to use a library or something. Richard Tingle In lue of a tutorial
