CubeEngine

CubeEngine is a rendering engine written in C++, developed as a personal hobby project and for portfolio purposes. This engine utilizes an integrated renderer based on both OpenGL, Vulkan and DirectX 12. The primary objective of this project is to implement features learned from college courses, particularly those focused on OpenGL graphics. Furthermore, the project aims to adapt and apply these OpenGL-based techniques to Vulkan, DirectX 12, thereby gaining proficiency in three graphics APIs.

Minimum Requirements

1. Latest Graphics Driver
2. GPU with Vulkan version 1.4.304.0 or above supported
3. Discrete GPU recommended
4. Download Vulkan SDK Minimum Version 1.4.304.0

How to Build

Currently it only supports MSVC compiler(Visual Studio 2022 Recommended).

1. Open CMD at a root directory.
2. Input "mkdir build" -> "cd build" -> "cmake .."
3. Set "Project" project as a startup project

All required APIs and Libraries are integrated in Project.

How to Compile Slang Shading Language

To compile Slang Shading Language, slangc is required. slangc is able to download from the following link or included in the Vulkan SDK since version 1.3.296.0.

Shaders are located in Engine/shaders.

1. From .slang to .glsl

GLSL
slangc Skybox.slang -profile glsl_460 -entry vertexMain -stage vertex -target glsl -o Skybox.vert

slangc Skybox.slang -profile glsl_460 -entry fragmentMain -stage fragment -target glsl -o Skybox.frag

2. From .slang to .spv

SPIR-V
slangc Skybox.slang -profile glsl_460 -entry vertexMain -stage vertex -target spirv -o Skybox.vert.spv

slangc Skybox.slang -profile glsl_460 -entry fragmentMain -stage fragment -target spirv -o Skybox.frag.spv

3. From .slang to .hlsl

HLSL (Add -D__hlsl__ when converting to HLSL)
slangc Skybox.slang -profile sm_5_1 -entry vertexMain -stage vertex -target hlsl -o Skybox.vert.hlsl -D__hlsl__

slangc Skybox.slang -profile sm_5_1 -entry fragmentMain -stage fragment -target hlsl -o Skybox.frag.hlsl -D__hlsl__
