 Axomae is a 3D rendering engine and raytracer, designed as a foundation to explore advanced rendering techniques .    
 The goal of the software is to facilitate the implementation of rendering algorithms and display of photorealistic images. 
 At the same time, the application is intended to be interactive , and customizable.

 * Nova: A multi-thread path-tracer , currently implemented to be scalable and distributed on GPU. Nova can be used as an offline renderer, or a pseudo-realtime , more interactive viewer. 
 * UV-editor
 * (Old feature) A normal map generation tool : Will probably be scrapped for an entirely new material generation pipeline. 
 * .hdr texture viewer.
 * PBR rasterizer 3D viewer.

 Axomae doesn't support in-source builds, so I suggest building in the parent folder: 
 Note that: 
 
-1) Unit tests building is enabled by default , set ```-DAXOMAE_BUILD_TESTS=OFF``` if not needed. 
-2) QT's repository layout is downloaded by default, and can be enabled in case we want to build QT from source . Use ```-DAXOMAE_FROMSOURCE_QT_BUILD=ON```.
-3) For CUDA , use ```-DAXOMAE_USE_CUDA=ON```.
+- Building Unit tests is enabled by default , set ```-DAXOMAE_BUILD_TESTS=OFF``` if they are not needed. 
+- Building QT from source is enabled by default. It is more reliable to build Axomae and it's dependencies through a unique toolchain, but it will take longer(~15 min on an 8 cores ... Build time optimizations are on the backlog. )
+- If nonetheless you can use your own QT system library , use ```-DAXOMAE_FROMSOURCE_QT_BUILD=OFF``` .
+- For CUDA , use ```-DAXOMAE_USE_CUDA=ON```.

 $ cd Axomae
 $ cmake -S . -B ../build -DAXOMAE_BUILD_TESTS=OFF -DAXOMAE_FROMSOURCE_QT_BUILD=OFF
