Graphics-project

——复旦大学2023年春《计算机图形学》课程项目
Computer Graphics Course (COMP130018.01, 2023 Spring) Project of Fudan University.
A copy of MIT 6.837, including Curves-surfaces(assn1) and Ray-casting-tracing(assn4, assn5).

Project1--曲线和曲面造型技术

分支切换

git checkout Curves-surfaces

环境搭建（linux）

sudo apt-get install build-essential cmake
sudo apt-get install freeglut3-dev xorg-dev libxrandr-dev libsdl2-de

编译运行

mkdir build
cd build
cmake ..

make
cd ..
build/a1 ./swp/circles.swp

样例结果查看

chmod a+x sample_solution/athena/a1
sample_solution/athena/a1 swp/core.swp

Part1--曲线的绘制

测试：

build/a1 ./swp/core.swp

Part2--曲面的绘制

测试：

build/a1 ./swp/wineglass.swp

build/a1 ./swp/weird.swp

Expansion--曲面的闭合问题

测试：

build/a1 ./swp/weirder.swp

Project--2 光照模型与光线追踪

分支切换

git checkout Ray-casting-tracing

环境搭建（linux）

sudo apt-get install build-essential cmake
sudo apt-get install freeglut3-dev xorg-dev libxrandr-dev libsdl2-de

编译运行

mkdir build
cd build
cmake ..

make
cd ..
//结果图片将保存到`test_out`文件夹下
build/a2 -input data/scene01_plane.txt -output test_out/01.png -size 200 200

样例结果查看（结果图片将保存到sample_out文件夹下）

chmod u+x sample_solution/athena/a2
sample_solution/athena/a2 -input data/scene01_plane.txt -output sample_out/01.png -size 200 200
sample_solution/athena/a2 -input data/scene06_bunny_1k.txt -output sample_out/06.png -size 300 300 -bounces 4
sample_solution/athena/a2 -input data/scene07_arch.txt -output sample_out/07.png -size 300 300 -shadows -bounces 4
