OpenGL implementation of 3D chair in c++ using GLFW, Glad and GLM. This is one of my college project for computer graphics. I just wanted to share this project to help anyone learning graphics. This project was done long time ago and I have forgot many stuffs about graphics. So I might be unable to help anyone who face issues while compiling and running this project. I myself spent a whole day setting this project up and running and I can tell you it wasn't fun.
I have used cmake to generate the build and make to build the project. First you have to install cmake and make. If you are using linux you can use your package manager to install the tools. Most probably it would be installed by default.
I will be using linux, for other operation system please google search for equivalent operations.
Clone the project and change directory to build
cd build
Run cmake to generate the build and then use make to compile the project
# cmake to build the project build
cmake ..
# compile project
make
If the compilation is successful, then run the generated executable
./3DChair
The chair is rendered using concept of cube. It consists of 20 cubes which are generated programmatically.
In the figure above leg with 1 is a cube with small length and breadth but large height. And the arm rest with 2 is another cube with small length and height
but large breadth.
This project uses vertex_shader.glsl for computing the position of the chair. The light effects are computed using fragment_shader.glsl.
This project implements the phong model for illuminations. You can look into fragment_shader.glsl to understand how specular, diffuse and ambient light reflections are computed.
The project supports basic inputs from keyboard to manipulate the chair. The keys and their functions are given below.
| Keys | Operation |
|---|---|
| LEFT and RIGHT | Rotation about X-axis |
| UP and DOWN | Rotation about Z-axis |
| W and S | Translation about Z-axis |
| A and D | Translation about X-axis |
| + and - | Ambient light control |
