QUESTION

threebox "projectToWorld" returns values exceeding canvas, how do I fix this? (with sample code)

Asked 2021-Jun-12 at 22:39

I recently found out there is a very handy method in three-box for placing three.js objects on the map which is "projectToworld".

While trying to place my three.js objects using the method, I realized that the Vector3 the method returns are really huge and not on the map.

According to the documentation of threebox, it says

projectToWorld

tb.projectToWorld(lnglat) : THREE.Vector3

Calculate the corresponding THREE.Vector3 for a given lnglat. It's inverse method is tb.unprojectFromWorld.

So I decided to use this method to locate my animated object in three js canvas. But what the methods returns are really huge.

So as I expected, these values don't place the three objects on the map and all the objects disappeared because they presumably are placed at very distant locations.

How do I fix this issue?

I made a minimal code to demonstrate this issue as below.

It's strange that no one could answer this question. So I finally figured out how to make it by myself.

The solution is in the following link.

The primary reason was that mapbox plots things not based on its vector configuration. It renders things through its matrix as follows.

var m = new THREE.Matrix4().fromArray(matrix); var l = new THREE.Matrix4().makeTranslation(modelTransform.translateX, modelTransform.translateY, modelTransform.translateZ) .scale(new THREE.Vector3(modelTransform.scale, -modelTransform.scale, modelTransform.scale))

QUESTION

Interactive debug console for scala in Intellij?

Asked 2021-Jun-08 at 05:49

I am learning scala in my free time. When I was programming in python with Pycharm, Pycharm provides a very handy tool called debug console which, if I set a breakpoint at line L, would store the value of the variables by the time of L, and I can freely explore some operations on those variables.

I know scala has a REPL tool and I am wondering if scala in Intellij IDEA has the similar debug console. I know I can use evaluate expression tool but it is a little difficult to use because

I can't see the previous calculated expression values and I have to retype every time to see the values.
I can't store the result of the expression on one variable and continue using that variable.

Thanks!

ANSWER

Answered 2021-Jun-08 at 05:49

If you set a breakpoint on a line (click in left margin to get a red dot) and then Debug rather than Run (bug icon rather than play icon) then IntelliJ will stop at the first breakpoint and show a very comprehensive debugging window. You can evaluate an expression (calculator icon) and create a watch expression which is evaluated each time a breakpoint is hit (watch panel on the right).

GithubActions CI Windows VMs don't have fsi.exe anymore? or it changed location

Before you tell me that the way to run .fsx scripts in .NETCore/.NET5(or higher) is dotnet fsi, FYI: I know that already. I just can't upgrade yet, so I'm still running my .fsx scripts with the good-old .NET 4.x Framework.

ANSWER

Answered 2021-Jun-02 at 15:14

It looks like the location changed recently for me also:

VS2019 version 16.9.3: ...\Microsoft\FSharp\fsi.exe
VS2019 version 16.10.0: ...\Microsoft\FSharp\Tools\fsi.exe

So they've moved it into a Tools directory for some reason.

What I do personally is start the "Visual Studio 2019 Developer Command Prompt" and execute fsi from there, so the exact location doesn't matter. Maybe you can script something similar by invoking the same command file? It's in ...\Common7\Tools\VsDevCmd.bat.
