Ivan Sutherland : Sketchpad Demo (2/2)

When the host started talking about 3D I was thinking: nah man, they'll do it later. Why did you have to bring that up? XD
I was surprised to hear "yes" from the other man.
However, they seem to have had some problems with surfaces too :-)
But anyway, this is great stuff.

Superb! Thanks for posting this, it really puts the progress of CAAD in perspective and makes evident the huge contribution that many researchers and scientists have made to the progress of architecture and engineering today.

Qué pasada... y pensar en lo que ha evolucionado todo este mundo del CAD.
Pero aún así... parece que todo nació de ahí, de las ideas de estos auténticos flipaos de la vida. ¡¡Viva el MIT!! ¡VIVA!

I guess they did it directly by algorithm during drawing of the lines instead of an z-buffer. Memory at that time was still handmade and came in 64 byte blocks - and thats really bytes, not kilobytes.
So z-buffering and rasterdisplays were not really an option.

This was a vector based screens. It was really hard to do hidden line removal on those. The machine probably had a resolution of 1024x1024 or something.

lol, he's using a wii remote

hahahha! Thats a gud one!

This reminds me of CADAM which came out around 1980- except that Ivan's system was faster. CADAM dragged back then. It ran off an IBM 360 and took forever to do anything. Then it crashed several times a day on top of that. Growing pains.

Oh yes! I did have nightmares of rooms getting larger / or i smaller!
