Vulkan Graphics Engine with Voxel Terrain Generator

This repository contains a basic Vulkan graphics engine implemented in C++ using CMake. It provides abstractions for common Vulkan logic, making it easier to develop graphics applications. Additionally, a branch has been created to develop a small voxel terrain generator using the engine from the main branch. Everything is still very much work in progress and will continue being developed over the summer of 2023. Features

• Abstractions for common Vulkan logic, including surface creation, command pools, synchronization structures, and command buffers.
• Support for validation layers in debug builds.
• Buffer and image creation helpers.
• Buffer management for efficient data handling and memory allocation.
• VMA (Vulkan Memory Allocator) integration for managing Vulkan memory.
• Swapchain support and surface capabilities querying.
• Queue family and device extension support checking.

Prerequisites

• C++17 or higher
• CMake (version 3.15 or later)
• Vulkan SDK

Getting Started

To use this Vulkan graphics engine and voxel terrain generator, follow these steps:

• Clone the repository and navigate to the project directory.
• Install the required dependencies.
• Build the project using CMake.

Engine Usage

The coral_device class provides the main interface for the Vulkan graphics engine. It handles device initialization, command buffer creation, buffer and image management, and more. Refer to the coral_device.h header for a quick look of the available methods. The coral_buffer class provides buffer management for efficient handling of data. Refer to the coral_buffer.h header for a quick look of the available methods.

Voxel Terrain Generator (WIP)

The voxel terrain generator is being developed on a separate branch from the main engine. You can switch to the branch and explore the code to understand the implementation. It is still very much a work in progress and is actively being developed.

Roadmap:

• A definitive world generation algorithm using perlin noise (it only generates flat chunks as of now).
• Async chunk generation.
• Chunk manipulation (you cannot place or destroy blocks as of now).
• Multiple, configurable biomes for use in the world gen. algorithm.
