So please enjoy my worst-code-ever collection:

A boolean with exceptions:

How shall we deal with it, when there is not file?

I am still remembering this one!

An unoptimized array

When I started to work on C++ with dynamic allocations I needed a way to add new items to my “array”. So my solutions looked like …

… which…


And so it happens really often that some developers ( for instance: me ) are starting a lot of side-projects … which is good … but none of these projects will get finished … this is not so good.

So what is the trick to get things done? If you are searching in Google…


Introduction

I am working on the Asset-Importer-Lib since 2006. At first, we were three guys who wanted to share their file-loaders in one library with others. If you have ever tried to import any kind of 3Dfile–format you know how much work, frustration, and pain this will cause. A lot of hacks and special implementations for special use-cases are part of most of the formats I worked with. A lot of great developers helped us by writing importers, their knowledge, and bugfixes. So the code-base has grown over the years. So did the tech-debt’s. …


My first C++-code I wrote was a finite-element-solver ( in short FE ) for my master-thesis. The task was complex: implement a non-linear algorithm to calculate the maximum possible load for user-defined 2D-steal structures by using the plastical capacity of steal-beams. You can use this algorithm to design much more filigree steel-structures than using only the elastic capacity. This helps a lot to save steel and money.

The task in short:

  1. You need to write a FE-solver for 2D-beam-elements
  2. Calculate the forces and moments for your model
  3. Increase the loads until they reaches the boundary of the elastic capacity
  4. Add…

When I started my career as a professional software developer in 2003 my first task was to improve a…


In this blog-post I want to explain a simple strategy how to optimize your performance when you want to render a 3d-model imported by the Asset-Importer-Lib ( see https://assimp.org/ ).

When you have imported your asset by using the Asset-Importer-Lib the data-structure stored in the plain c-struct aiScene contains different data:

  • The vertex-data like positions, normals, texture coordinates are stored in instances from type aiMesh
  • The referenced material-data which is assigned to each mesh instance. Each material-definition is stored in aiScene-instance and each mesh holds an index to this material in the array. …


It is an easy tool for debugging: You can add checks in your code if your application is in a dedicated state. When this is not the case it will stop your application but only when you build it in debug mode. In release-mode the tests will be ignored.
Depending on your platform this can vary a little bit. …


Your Ground Zero:

Imagine the following situation: you are starting a new job, you are looking forward for a bright future in this new company. Of course you are planning to use the newest technologies and frameworks, you will invent new way how to design the world etc. . Because you know development, you know how to build things, you know what users wants.

And then you are allowed to take a first look into the source you have to work with. No tests, no specs, no documentation of course. But what you now have are a lot of upset customers. Welcome to…
