Sierra

About

Sierra is a heightmap editor focused around sculpting virtual terrain. It supports saving raw 16-bit heightmaps (.r16) that can be imported into other tools such as Houdini. I decided to build it to learn C++, OpenGL and WPF.

The 3D viewport and core application logic is implemented in C++ and leverages OpenGL for rendering. The application UI is built using C# and WPF, targeting .NET Core.
