It's almost like a caricature of a CRT. I can see the novelty, but hope that people aren't lead to believe monitors looked like this.
I think what bothers me most is the horizontal line that slowly moves across the screen every few seconds. It's an artifact of recording a CRT on film and doesn't occur when you look at a real monitor...
- rbanffy 10mo agoIt could happen in home computers connected through the antenna input. I think if power was slightly off the desired frequency this could also happen, but we’d need to test.
- ack_complete 10mo agoIt also happens with digital cameras for similar reasons, due to CCD scanning. But yeah, that doesn't happen looking directly at a CRT. The bloom is also too blobby, because it's a gaussian blur. I ran into the same issue trying to implement a similar effect. The bloom shape needs to sharper to look realistic -- which also means unfortunately a non-separable blur.
- derefr 10mo agoA horizontal-line artifact (not the one depicted in the shader) could totally happen, if you were over-driving a monitor with a higher pixel clock than it was happy with. With this kind of artifact, the two halves of the image would also be slightly horizontally misaligned with respect to one-another, too.
