Installation

Prerequisites

For runtime GLSL kernel compilation (v0.2+), FastGPU requires the Vulkan SDK to be installed on your system to provide the glslc compiler. You can install it easily via winget:

winget install KhronosGroup.VulkanSDK

Demo Launcher

• run-demo.bat starts the existing FastGPU demo.
• run-demo2.bat starts the new fast fluid demo from examples/Demo2.

Option 1: Maven (Recommended)

Add the JitPack repository and the dependencies to your pom.xml:

<repositories>
<repository>
<id>jitpack.io</id>
<url>https://jitpack.io</url>
</repository>
</repositories>
<dependencies>
<!-- FastGPU Library -->
<dependency>
<groupId>com.github.andrestubbe</groupId>
<artifactId>fastgpu</artifactId>
<version>0.1.0</version>
</dependency>
<!-- FastCore (Required Native Loader) -->
<dependency>
<groupId>com.github.andrestubbe</groupId>
<artifactId>fastcore</artifactId>
<version>0.1.0</version>
</dependency>
</dependencies>

Option 2: Gradle (via JitPack)

repositories {
maven { url 'https://jitpack.io' }
}
dependencies {
implementation 'com.github.andrestubbe:fastgpu:0.1.0'
implementation 'com.github.andrestubbe:fastcore:0.1.0'
}

Option 3: Direct Download (No Build Tool)

Download the latest JARs directly to add them to your classpath:

1. 📦 fastgpu-0.1.0.jar (The Core Library)
2. ⚙️ fastcore-0.1.0.jar (The Mandatory Native Loader)
