Requirements

• Windows 7 x64 or newer, macOS 10.12 or newer, or Ubuntu 16.04
• A graphics card that supports OpenGL 3.3+

Features

• Friendly, simple and convenient GUI.
• Readable, clear code structure which is easy to expand.
• Supports reading and saving 3D model files in 40+ formats, including FBX, DXF, Collada, Obj, X, PLY, 3DS, etc.
• Supports reading and saving the entire project (using the file type *.aeproj defined by this engine)
• Uses tree structure to describe the scene, supports basic transformation (translation, rotation, scaling) on model and mesh.
• Supports diffuse maps, specular maps, and normal maps.
• Supports ambient light, directional light, point light, and spotlight. You can create not more than 8 lights of each type. For each light, you can adjust its color, position, and many other properties.

Advanced User Manuals

The advanced user manuals cover the implementation of custom functions using API provided by Ash Engine. This requires the user to be familiar with C++ object-oriented programming and some Qt classes (such as QVector3D).

Note: Read the basic manuals first before you start to read any advanced manual.

Build from source

Note: This project was built under Qt 5.9.7. No matter which platform or IDE you use, you must install Qt first.

Three main platforms are supported:

• Windows 7 x64 or newer
• macOS 10.14 (Older versions may work too)
• Ubuntu 16.04 LTS (Only tested on 16.04, other versions may work too)

It takes about 3 minutes to build on a laptop with Intel Core i5-5257U (single thread).
