K3D

K3D is an easy-to-use, lightweight 3D library designed for Android developers. The purpose is to allow Android developers to easily achieve various effects without touching the underlying graphics API.

Still working on it and it's not ready for testing or use. But I am welcome to any suggestions or contributions.

Why K3D

K3D provides a solution for developers with lightweight 3D needs. Compared with using the game engine directly, it is more lightweight, focused and rendering. It is written in pure kotlin and is easy to interoperate with native applications. It is simple, provides a declarative API, and only requires a few lines of code to complete the scene construction.

Getting Started

// settings.gradle.kts
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()

        // Add the snapshot repository to your settings.gradle.kts
        maven("https://s01.oss.sonatype.org/content/repositories/snapshots")
    }
}

// build.gradle.kts (app)
dependencies {
    // Add the dependency to your build.gradle.kts
    implementation("me.rerere:k3d:1.0.0-SNAPSHOT")
}

Check the app/MainActivity.kt for basic usage. Check the app/DslExample.kt for declarative API
