    Tutorial Series - Introduction to Direct3D with XAML application development for Windows Phone 8 : Transformation Matrices

    Transformation matrices

    I will dedicate this post to matrices. If you missed this mathematical discipline thinking it was probably useless: bad luck, in the world of 3D rendering this topic is essential! :)

    A simple explanation (basically) is that each matrix is ​​defined as an array of numbers (4x4 in our case) which will simplify our life for applying transformations to the cube mesh (rotation, translation and scaling). As I do not claim to give you an algebra class (that my notions are actually quite limited), I suggest you to visit the resources section at the end of this article (stolen on a previous post from my colleague David Rousset ^^):

    Before depressing, the good news is that Direct3D manages much of the inherent complexity of the matrices, the important point to understand is that the coordinates of our object (vertices in first) will be transformed in the following way.

    1. In the first place, we will apply transformations on the object (model) to position it appropriately in the scene.
    2. Then, we'll look at this object from a certain point of view. Imagine a camera that fits over our cube. We will apply the appropriate transformations to see the object in the new coordinates system.
    3. And finally the projection. It is nice to be in a 3D world, but our screen is a flat surface where each pixel is represented by 2 values (x and y). Projection will help us to switch from the 3D world to the 2D surface.

    These transformations are defined by different matrices: model, view and projection. Our initial data (stored in the Vertex Buffer) will be transformed by these matrices to obtain the final coordinated of our pixel on the screen.

    This is largely the role of the Vertex Shader (yet another technical term ^^) to perform this operation. How does it do? It will simply multiply the starting coordinates with each matrix model, view and projection, job completed!
