marching | A JavaScript library that compiles GLSL ray marchers | Graphics library

I am trying to implement marching cubes into my game, and so far I have set up a system for drawing triangles with four points in world space. I have got the system working where I set the points, but then when I draw the two triangles to make it a mesh, it only draws one, but I set up a print() statement, and it shows that 2 triangles are drawn each time, so that is normal. I can't figure out what I need to do. Here is my code, and comment on this post if you need any more pics/code:

I made a voxel raycaster in Unity using a compute shader and a texture. But at 1080p, it is limited to a view distance of only 100 at 30 fps. With no light bounces yet or anything, I am quite disappointed with this performance.

I tried learning Vulkan and the best tutorials are based on rasterization, and I guess all I really want to do is compute pixels in parallel on the GPU. I am familiar with CUDA and I've read that is sometimes used for rendering? Or is there a simple way of just computing pixels in parallel in Vulcan? I've already got a template Vulkan project that opens a blank window. I don't need to get any data back from the GPU just render straight to the screen after giving it data.

And with the code below would it be significantly faster in Vulkan as opposed to a Unity compute shader? It has A LOT of if/else statements in it which I have read is bad for GPUs but I can't think of any other way of writing it.

EDIT: I optimized it as much as I could but it's still pretty slow, like 30 fps at 1080p.

Here is the compute shader:

I have been studying leetCode and I ran into this problem: Given a string s and an integer k, return the length of the longest substring of s such that the frequency of each character in this substring is greater than or equal to k.

The most elegant solution so far is below but I don't understand

A: What is it trying to do

I am experimenting with ray marching, and have been following Jamie Wong's tutorial.

When the moving the camera section comes, they use the function

Found code here for metaballs using vanilla javascript. Is there a way I can change the opacity of the metaballs? I think it should be a quick fix but im not too sure. I tried changing to CSS class bubbles but that didnt work so im assuming in needs to be in the Javascript. Anything helps, thanks.

I am working on a project with tf-idf, I have a column (df['liststring']) in my dataframe that contains the preprocessed text (without punctuation, stop words, etc.) from my various documents.

I ran the following code, and I got the top 10 words with the highest tf-idf values but I would like to see their scores as well.

I have multiple png files and I'm trying to get the polygon contour coordinates. That is the simplified coordinates, only each outer corner (not a convex hull polygon).

The program that will do this at the moment is python and opencv. But another program is oke I did try to fix this using npm packages, imagemagick, potrace, Lua. It will be uses as a shell command in a 'build polygons from images' process.

This was the last test under python.

The problem now is the that some edges are 'not' correct in the example below.

I did the following steps

• Convert the alpha to black and white
• Trace the contour
• Get the coordinates

1. The original png file contains black lines (keep them).

1. Converted black and white image (you can't see the top line, because this website have a white background)

I am trying to make a 3D-voxel game that uses the marching cubes algorithm to procedurally generate a game world. This is working fine so far, except that, on exactly perpendicular sides on the positive and negative x sides of a given perpendicular piece of the world/chunk mesh, it looks like the uv coordinates aren't quite right as it just displays a solid color instead of the texture.

At <2.> you can see the chunk wall how it is supposed to look like and at <1.> you can see the weird bug. This ONLY occurs on exactly perpendicular x-side triangles! Those meshes in the image are debug-chunks to show the problem. All the noise-to-terrain translation works fine and I don't get any bugs there. It's only the uvs that cause problems. I am using the following code to populate the Mesh.vertices, Mesh.triangles and Mesh.uv:
