Re: efficient polygon drawing

I think most of the things that are important are already mentioned by Daniel. In terms of speed, most cpu time is usually spend on the filling. This can be done horizontally (per scanline) or vertically (per y-block). Pulse contains both a xorfiler (for the cube) and a hline filler (for the tunnel)...

Re: RGB to HDMI does this work with a ST

Hahaha. So basically the VGA to HDMI converter doesnt solve anything really. Apart from that your display device may have different tolerances for HDMI than VGA input; so this works IF your display device can handle 15khz HDMI.

Re: RGB to HDMI does this work with a ST

Thanks for confirming that the vga>hdmi works at 50hz output. I have just ordered one to add to my collection of converters. The VGA > HDMI converter I already have does not produce any output. Im interested to see if this one does in my case!

Re: RGB to HDMI does this work with a ST

All those cheap HDMI converters; I've bought a ton of them and none have done 50 Hz motion. They have either dropped every second field of the PAL signal or added a de-interlace that merges fields. Either way, the end result is 25 Hz motion. Not good enough. Excuse my lack of proper eyesight :) - s...

Its aroundd 1 scanline for raw YM dump.
