## Introduction

gbox is a mutli-platform c graphic library. 

It is now in the early stages of development only for reference and learning.

If you are interesting to this project, please view the source code.

#### Features

- Support 2d vector drawing

- Support matrix transform

- Support fill and stroke for solid, gradient and image

- Support custom path and drawing

- Support float and fixed point computation

- Provide custom drawing devices

- Support OpenGL ES 1.0/2.0 

- Support soft algorithm for drawing

- Implement mesh structure and algorithm

- Implement complex polygon tessellator and triangulation

- Support odd and nonzero fill

- Implement polygon scanning algorithm

- Provide multi-platform windows(.e.g glut, sdl and x11, framebuffer, ios, android in the feature)

#### In the plans

- Draw svg images

- Implement anti-aliasing

- More drawing devices and windows

- Draw text 

- Development ui and game engine

#### Build

please install xmake first: [xmake](http://www.xmake.io)

    $ cd ./gbox

    $ xmake

#### Run

    $ xmake run core

## 简介

GBOX是一个用c语言实现的多平台图形库，支持windows、linux、mac、ios、android以及其他嵌入式系统。

现在这个项目，正处于早期开发阶段，暂不提供使用，仅供参考学习

如果您感兴趣，可以阅读源码

#### 已实现的功能

- 矢量2d渲染，支持矩阵变换，画刷、画笔的设置和渲染

- 支持复杂矢量路径渲染和填充

- 支持纯色填充、梯度填充、图像填充（正在重构）

- 支持全定点或者浮点计算（可配置切换）

- 实现渲染设备扩展，目前支持gpu加速的opengl es 1.0/2.0设备、纯算法渲染的bitmap设备

- 实现复杂多边形分割（三角形分割、凸多边形分割），支持奇偶填充、非零填充等填充规则（这个算法花了我一年时间 =。=）

- 实现mesh结构和封装

- 实现多边形扫描算法

- 支持多平台窗口扩展，目前支持glut、sdl窗口，后续会支持（x11，framebuffer, ios/android，windows等原生窗口）

#### 后续工作

- svg矢量图形渲染（之前的版本实现过一整套，最近正在重构，所以暂时移除了）

- 反走样支持

- 实现更多平台窗口和渲染设备

- 实现字体渲染

- ui框架的实现

- 有时间的话，再整整游戏引擎，当然这个是后话，看心情和时间了。

#### 测试效果

- 目前基于opengl的渲染设备，绘制tiger.svg可达到60fps

- 基于bitmap的纯算法渲染设备，绘制tiger.svg可达到30-40fps（pc上测试，数据仅供参考）

#### 编译

请先安装: [xmake](http://www.xmake.io)

    cd ./gbox

    xmake

#### 运行

    $ xmake run core
