# DTRenderer
|
|
DTRenderer is an attempt to build a simple software renderer from the ground up. The main goal is to build an intuitive understanding of graphics mathematics, rendering pipeline and core concepts. It runs as a Win32 program with minimal dependencies.

|
|
|
|
The following resouces have been largely informative to my understanding of the software renderer,

* [Handmade Hero](http://handmadehero.org/)

* [Optimising Software Occclusion Articles](https://fgiesen.wordpress.com/2013/02/17/optimizing-sw-occlusion-culling-index/)
|

## Building
|
|
DTRenderer is a Win32 program and can be compiled with **build.bat** which requires Microsoft Visual Studio **cl.exe** to be in the Windows path. It is originally built using Visual Studio 2017, older versions are still somewhat compatible, albeit there are some switches which have been renamed in the 2017 edition.
|
|
|
|
The Visual Studio solution file is provided as a thin wrapper for interfacing with the Visual Studio debugger and **can not be used to compile.**

|
|
* SIMD "Optimisation" _(with a grain of salt, tried to with some % improvements)_
|
|
|
|
## Libraries
|
|
The external libraries that have been used,
|
|
* STB Single File Libraries
|
|
* STB Image _(for image loading)_
|
|
* STB TrueType (and RectPack) _(for creating bitmap font)_
|
|
|
|
### Debugging Libraries
|
|
These libraries are non-essential and used for validating results and debugging the program.
|
|
* STB ImageWrite _(for debugging renders, TrueType output etc.)_
|
|
* EasyProfiler _(for profiling)_
|
|
* TinyRenderer _(for comparing data output for validity of results)_
