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

=== Bonus Points ===
 +
''Submit with Stage 3''
 +
 
 +
Extend your visualization options by the following features to earn bonus points. Attention: Your point total (including bonus points) will not exceed 25 points for exercises from computer graphics part.
 +
 
 +
; Material Properties (1p)
 +
: Expose material properties ka, kd, ks, shininess, and color to GUI. Re-render image when the user changes these properties.
 +
 
 +
; Lighting Model Selection (2p)
 +
: Implement a switch that allows the selection between two lighting models (Phong vs Blin-Phong). The difference should be minimal but it is a proof of concept.
 +
 
 +
; Light Types (3p)
 +
: Add possibility to select the light type (point light, sun/directional light) - the GUI option should also change from "light direction" to "light position".
