PB Engine

Feature Set of the PB Engine

The PB Engine is a custom-built, high-performance game engine designed for modern voxel-based projects, physically based rendering (PBR), and real-time graphics applications. Developed with C++, Vulkan, and Lua scripting, it provides a robust foundation for rendering, physics, animation, and gameplay systems.

Rendering & Graphics

• Vulkan-based renderer optimized for high-performance real-time rendering.

• Physically Based Rendering (PBR) pipeline with support for HDR lighting, and tone mapping.

• Custom shader system, allowing for GLSL-based materials and easy integration of advanced shading techniques.

• Efficient texture management, including mipmap generation, HDR textures, and Vulkan image transitions.

• Skeletal animation support, with optimized bone influence limits for efficient vertex skinning.

Physics & Animation

• Skeletal animation system, designed for smooth interpolation and real-time playback.

• Collision detection and response, integrated with the voxel-based world structure.

• Custom math libraries for vector, matrix, and quaternion / rotor operations, designed for game-specific transformations.

Scripting & Modularity

• Lua scripting integration via the Sol library, allowing for flexible game logic and modding support.

• Custom Lua bindings for engine components, including actors, input, and game logic control.

• User-defined helper functions for extending engine behavior without recompiling.

• Component-based actor system, allowing for modular gameplay object creation.

Tools & Development

• Model Importer using ASSIMP.

• FreeType-based font rendering, capable of generating glyphs as meshes for 3D UI elements.

Optimization & Performance

• Multi-threaded job system, for easy parallelization of expensive operations.

• Memory-efficient texture and buffer management, leveraging Vulkan Memory Allocator (VMA).

• Asynchronous resource loading, allowing for background asset streaming without frame drops.
