Light Pen, Computer Science Lecture | Sabaq.pk

Back in the 1960s, scientists were already experimenting with what looked like touch-screen tech and early 3D graphics 💻✨ In a 1967 news clip, a device called the light pen let users draw directly on a screen — and instantly see their designs turn into 3D visuals. It was decades ahead of its time, mostly used in research labs and military projects, but it marked the true beginning of computer graphics. As computers evolved, so did 3D modeling — shaping everything from modern design tools to the
