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
