3dzavr's Introduction

🚀 3Dzavr - Light C++ Game Engine

MIT License Community Discord Commits Issues Repo size version

About:

3Dzavr is yet another 3D engine for C++ that uses SDL as multimedia framework.

Motivation:

Initially this project was created as a Proof Of Concept in implementing custom CPU render from scratch.
Gradually, 3dzavr became more like a very simple version of big engines like Godot, Unity or Unreal.
Our goal is to create light and easy to use/study/contribute Open Source and free engine, which anyone can access and use in whatever purposes.
But the main goal is to have fun! You are welcome to use and contribute!

Main functionality:

  • Operations with vectors, matrices, triangles etc
  • Projections from 3D on 2D plane, movement and rotation of camera and meshes
  • The custom light component system
  • The system of attachments and hierarchy tree
  • Advanced smooth animations by using Bézier curves for meshes and camera
  • Collision detection (GJK) and resolution (EPA)
  • Resource manager and other useful utils

Installation (Linux):

  1. Update apt packet manager: sudo apt update
  2. Install gcc and c++ compilers: sudo apt install gcc and sudo apt install g++
  3. Install SDL2: sudo apt-get install libsdl2-dev
  4. Install SDL 2 TTF (for working with fonts and text): sudo apt install libfreetype6-dev libsdl2-ttf-dev libsdl2-ttf-2.0-0 -y;
  5. Install libpng library: sudo apt-get install libpng-dev
  6. Install pkg-config: sudo apt-get install -y pkg-config

So clang must be used for building 3dzavr now. It can be set with this command:

cmake -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_EXE_LINKER_FLAGS="-fuse-ld=lld" ..

Painter's algorithm problem

For now I use average z of triangle to sort them in correct order:

double z1 = t1[0].z + t1[1].z + t1[2].z;
double z2 = t2[0].z + t2[1].z + t2[2].z;
return z1 > z2;

where t1 and t2 - two triangles to compare.

But anyway we have glitches when some triangles wrongly overlap other triangles.
Example:

Still maintaining?

Wanted to ask if something is planned for this? Like Texturing and Lighting and other file formats like .glb
