### Slides

### Project

Choose programming language of your liking (suggested Python/Java/Javascript)

Finished project send to *adam.riecicky@fmph.uniba.sk*

#### Stage 1 (3p)

*Deadline 24.11.2019 23:59*

Create a simple loader and visualizer of meshes, stored in obj. file format.

- Structures
- implement IndexedFace which contains
*array of Vec4 vertex positions*and*array of Int indices* - Mesh import and display
- load mesh from Wavefront file (.obj). [Download test models here]. Assume that all imported models are scaled to box (2x2).
- display wireframe model in the center of a screen so that the Y-axis of model directs upwards and X-axis directs right. (Z is ignored)

#### Stage 2 (10p)

*Deadline 15.12.2019 23:59*

Add transformation controls to your tool.

- Structures
- implement math types
*Mat4*and*Vec4*. - Add functions
*Multiply(Mat4, Mat4)*,*Multiply(Mat4, Vec4)*OR override the multiplication operator. - Transformations - must be implemented using matrix multiplication!
- Add buttons that can control the transformations of the model. When a user requests transformation by clicking a button, a model matrix should be constructed. (Optionally added to the previous transformation)
- Motel matrix can be
*reset to identity*using a Reset button - Construct a projection matrix which performs primitive orthogonal projection and transforms the object into the viewport (scale and translate as in the previous stage)
- Always store the original model. Model transformation and projection is done for each point just before rendering

- Examples of the functional program
- screen 1 = Import only
- screen 2 = Import only
- screen 3 = Imported, translated by -0.6 in X-axis, rotated by 0.6 rad around Y-axis, rotated by 0.4 rad around Z-axis and scaled by factor 1.1, in order

#### Stage 3 (7p)

*Deadline 12.1.2020 23:59*

Enhance existing visualization tool by implementing Blinn-Phong Lightning Model

- Mesh display
- Implement back-face culling. Faces on the far side of the mesh should not be rendered
- Display solid model - each face is a drawn as a polygon filled with color (no edges)
- Final face color should be calculated as multiples of base color and intensity calculated by Blinn-Phong
- Controls
- Add an interface to control the direction of incoming light
