YwSoftRenderer

Implementing a Soft Renderer for Learning CG.

About

Mostly coming from Muli3D, improved by my understanding. It is still a long and hard trip, but worthwhile.

Build

Premake5 is used to build the project, so you need to download a Premake5 execuatable file and put it into the project root directory.

Next, open a command window and type the generating command, e.g.

premake5 vs2017

or

premake5 vs2015

(Currently only support Windows platform, other platforms like OSX and Linux is still on the schedule.)

After executing the command "premake5 vs2017", you can find the Visual Studio solution files at "$(ProjectRoot)/Workspace/vs2017/YwSoftRenderer.sln", open it with Visual Studio and build the solution, all demo executable files are located at "$(ProjectRoot)/Binaries/".

Progress

  • Math support.
  • Base rasterization and rendering stuffs as Muli3D supported.
  • Premake5 support.
  • Input module.
  • Stencil Buffer support.
  • State Block optimize with pooling.
