Episode notes
Teaching Through OpenGL Tutorials
- Etay Meiri started OpenGL tutorials because he found teaching helps understanding complex topics.
- He chose OpenGL over DirectX due to using Linux at home and wanting to share knowledge.
Switch from Virtualization to Graphics
- Etay transitioned into graphics programming after a failed virtualization project at Intel.
- He worked on offloading vertex shading from GPU to CPU for improved integrated GPU performance.
Evolution of Real-Time Graphics
- Early computer graphics evolved from 2D to 3D with games like Doom bringing real-time 3D rendering.
- The programmable GPU pipeline replaced fixed functions allowing custom vertex and fragment shaders.
