# opengl-texture-mapping
This project aims at mapping various textures (bmp images) onto objects specified in the .obj format.
### Features implemented
- Viewing .obj files in a window, with rotate and scale enabled
- Specular, ambient and diffused illumination implemented
- Texture mapping has been implemented with the following parameters:
- `GL_REPEAT`
- `GL_CLAMP_TO_BORDER`
- The texture coordinates have been generated using two different algorithms:
- Planar Mapping
- Spherical Mapping
Any combination of the above metrics can be used to obtained various kinds of texture mapping, some of which have been provided as examples.
- The style of mapping can be modified by changing the third parameter of the function call `glTexParameteri` in texture.cpp to any of `GL_REPEAT`, `GL_CLAMP_TO_BORDER`, `GL_CLAMP_TO_EDGE`,`GL_MIRRORED_REPEAT`
### Library dependencies
- lGL
- glut
- GLEW
- glm
*Please have a look at the Makefile too to know what all libraries are being linked*
### Demo Scripts
- `fixed_linear.sh`
- `projective_linear.sh`
- `reflective_sphere.sh`
- `static_sphere.sh`
*Note: Remember to give the file executable permissions before executing.*
### Execution
The main executable is the `texture-mapping` whose commandline parameters take an `.obj` file, the vertex and fragment shaders and the bitmap ti be used as texture.
```bash
./texture-mapping
```
Rotation of the object happens as expected with the left mouse button and then dragging it. To pan press `F1` and then `F2` and then use the arrow keys. Use the `Home` key to reset the view.
