C++ 3D Game Tutorial Series: 10 | Rendering a 3D Cube | Source Code on GitHub


The source code of the 10th tutorial of the C++ 3D Game Tutorial Series is now available in early access on GitHub!

 

 

In this tutorial, we’ll learn to render a 3D cube by implementing:

  • Index buffer to optimize vertex data.
  • Vertex and Index data structure for a 3D cube.
  • Rotation matrices for X and Y axes.
  • Orthographic Projection Matrix to map 3D space to 2D screen.
  • Matrix composition to build a world matrix (combining rotation, scale, translation).
  • CPU-to-GPU data transfer for Projection Matrix with Constant Buffer.
  • Shader integration to position, rotate, scale and finally project the 3D cube on the screen.
