I am having trouble changing the colour of a vertex on a mouse click using three.js and Angular. I have been reading around this and I think I should be setting up vertex colours and then when I intersect against my scene I can use the color array in object.attributes.color. So this is what I have been attempting to do:

Apologies for asking a fairly common question, I have been looking all over and can't find a solution that fixes my problem.

I am using Firesharp, and trying to deserialize a Json object that Firebase returns into a class with a nested list.

I have created a three.js element to show a number of points on the screen and I have been tasked with clicking on two and calculating the distance between them. I am doing this in a Angular (8) app and have all the points visible and mouse events (pointerup/down) set up correctly. My idea is to ray trace from the mouse point when clicked and highlight a vertex (I do only have points no lines or faces). So I have attempted to set up Three.js RayTRacing on my scene but every time I call setFromCamera the camera is undefined even though I srill have the points visible on the screen at all times.

I am trying to rewrite this Apollo typescript repository to javascript. I try to learn typescript but there is one thing called 'type casting' or 'type assertion' which makes me confuse.

let me explain it with code:

//cache.tsx

Hello I am trying to make a line caster for those who don't know what that is it is a thing that gives you all the point in between 2 points and in this case I am writing this data to an image but for some reason when I run it it will only go up to the right (you will see what I mean if you run the code) does anyone know why this is here is my code and I am more than aware it is messy and not very efficient so suggestions to make it more efficient and or less messy are welcome

I've been searching through a lot of similar questions, but many are matching columns a bit differently and I haven't been able to adapt the awk commands people are sharing to work as I need.

Simply put I have 2 files, 1 with a list of basically names and duties. The second file has entries of items prepended by the same names listed in file 1, but there can be duplicate entries under a name in file 2.

Here's what some example data close to what I'm working with looks like

I am attempting to address the age old issue of model vs world space coordinates when adding light to a scene with transformed models.

I have a house model with two instances. a skull, a single point light in my scene as well as some terrain and a skybox. I noticed that when applying some rotations to my models, the illumination provided by the point light was rotating with it. After some reading it became obvious that I am doing all of my computations in my shaders in model space but my light position/directions are in world space.

So, I realized I needed to uniform my space for my calculations and I think it makes sense to keep the shaders in model space and convert the light components from world to model.

When I don't do the transformation it looks almost right (though not perfect which I'm betting is b/c of the different spaces). I render a small lightbulb model at the location of the light and the tops of the houses and the terrain all illuminate as I expect relatively well.

When I do the conversion of the light position back to model space I'm expecting the light to still be illuminating from the lightbulb model. However it gets wonky.

I have no rotations on the models but some minor translations so I'm confused as to why it seems like the light source gets rotated 90 degrees around the x axis...

I am making a ray caster, and I need to detect whether the rays intersect with the wall segments,

which I have the coordinates of each vertex to, does anyone know a way to do this?

I have looked it up, but I has yet to have found anything that could help me,

So I am asking here. Heres the code if you need to know (Use wasd to test it):

I'm making a ray-caster in JavaScript. How could I track Mouse X and Mouse Y? I've looked around but could not find anything that says anything about this specific situation..
