Teapot | weight URLSession wrapper for building simple API clients | REST library

I have a basic web server that renders blog posts from a database of JSON posts wherein the main paragraphs are built from a JSON string array. I was trying to find a way to easily encode new lines or line breaks and found a lot of difficulty with how the encoding for these values changes from JSON to GoLang and finally to my HTML webpage. When I tried to encode my JSON with newlines I found I had to encode them using \\n rather than just \n in order for them to actually appear on my page. One problem however was they simply appeared as text and not line breaks.

I then tried to research ways to replace the \n portions of the joined string array into
tags, however I could not find any way to do this with go and moved to trying to do so in javascript. This did not work either despite me deferring the calling of my javascript in my link from my HTML. this is that javascript:

I have created an array of objects(cups) which I have set a volume and capacity and colour too, all of this is displayed by calling .display() However I can get the display() to do this in this instance when trying to loop through the array of cups. I get no output to show the cups capacity and colour from the display() method, I have added the two bits of code, one in the cups class that contains the display method and the first one which shows me trying to create an array and display each cup. I would deeply appreciate any help as this is a part of a school assignment.

This is what I have as data in R:

I've been trying to test the API of restful-booker in Jmeter. But whenever I try to create a booking or Get a Booking by id I'm getting the HTTP response:418 'I'm a teapot'.If I try to access the URL in the browser it says the same. But when I run this in postman it does not give any kind of error. Also, it shows the correct response in Code Beautify. Really frustrating. Is there any way to resolve it?

...

What I want to do is if the http status code is 200 than add it to success, otherwise failure.

I was working on my ray tracer written in C++ following this series of books: Ray Tracing in One Weekend. I started working a little bit on my own trying to implement features that weren't described in the book, like a BVH tree builder using SAH, transforms, triangles and meshes.

NOTE: The BVH implementation is based on two main resources which are this article: Bounding Volume Hierarchies and C-Ray (A ray tracer written in C).

After I implemented all of that I noticed that there was some weirdness while trying to use some materials on meshes. For example, as the title says, the metal material looks completely black:

In the first image you can see how the metal material should look like and in the second one you can see how it looks like on meshes.

I spent a lot of time trying to figure out what the issue was but I couldn't find it and I couldn't find a way of tracking it.

If you want to take a look at the code for more clarity the ray tracer is on GitHub at https://github.com/ITHackerstein/RayTracer. The branch on which I'm implementing meshes is meshes.

To replicate my build environment I suggest you follow this build instructions:

$ git clone https://github.com/ITHackerstein/RayTracer

$ cd RayTracer

$ git checkout meshes

$ mkdir build

$ cd build

$ cmake ..

$ make

$ mkdir tests

At this point you're almost ready to go except you need the TOML scene file an the OBJ file I'm using which are these two:

• boh.toml (Scene file)
• teapot.obj (Teapot OBJ file)

Download them and place them in the build/tests and after that make sure you are in the build folder and run it using the following command:

$ ./RayTracer tests/boh.toml

After it finishes running you should have a tests/boh.ppm file which is the resulting image file stored using PPM format. If you don't have a software that let's you open it there are multiple viewers online.

NOTE: My platform is Linux, I didn't test it on Windows or Mac OS.

EDIT

Does the mesh work with other materials?

So as you can in the first image and especially in the second one we have we have some darker rectangular spots, and also the lighting seems kinda messed up. In the third image you have an idea of how it works on a normal primitive.

I'm trying to render a Teapot model from an OBJ file. I'm using the Fixed Function rendering pipeline, and I cannot change to the Programmable Pipeline. I would like to have some basic lighting and materials applied to the scene as well, so my teapot has a green shiny material applied to it. However, when I rotate the teapot around the Y-Axis, I can clearly see through to the back side of the teapot.

Here's what I've tried so far:

• Changing the way OpenGL culls the faces (GL_CCW, GL_CW, GL_FRONT, GL_BACK) and none produce the correct results.

• Changing which way OpenGL calculates the front of the faces (GL_FRONT, GL_CCW, GL_BACK, GL_CW) and none produce the correct results.

• Testing the OBJ file to ensure that it orders its vertices correctly. When I drag the file into https://3dviewer.net/ it shows the correct Teapot that is not see-through.

• Changing the lighting to see if that does anything at all. Changing the lighting does not stop the teapot from being see-through in some cases.

• Disabling GL_BLEND. This did nothing

Here is what I currently have enabled:

So I've tried to put labels on my objects. I tried out a test example to just put one simple label there. But when I put it there, something felt weird. The teapot was transparent!
