Stage 1 (13p)

Deadline 9.12.2018 23:59

Create a simple visualization and transformation tool for meshes, stored in obj. file format.

Structures
implement math types Mat4 and Vec4. Add functions Multiply(Mat4, Mat4) and Multiply(Vec4, Mat4).
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 Y-axis of model directs upwards and X-axis directs right. (Z is ignored)
Transformations - must be implemented using matrix multiplication!
Add buttons which can control transformations of the model. Each time 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 button
Construct projection matrix which performs primitive orthogonal projection and transforms the object into the viewport
Always store the original model. Do model transformation and projection for each point only 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 2 (7p)

Deadline 6.1.2018 23:59

Enhance existing visualization tool by implementing Blinn-Phong Lightning Model

Mesh display
Implement back-face culling. Faces on the far side of 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 a direction of incoming light

Examples of the functional program: screen 1, screen 2
