Re: Indirection operations

Thanks. I think its the base address Im feeding the plot routine is repetitively added in. However i noticed a load from sprite data operation had stopped working: LDA sp%,X works LDA (&77),X doesn't Where sp%=&C00 and !&77=&C00 That's because LDA (&77),X does not exist. You probably meant LDA (&77...

Re: Indirection operations

At first glance this code looks OK. However, it's pretty difficult to help you with only this part of the program to look at. For instance, maybe you forget to initialize something that subroutine plot relies on. Or your tables may be incorrect.

Re: Rotating 3D Earth (Elk/Beeb)

DFS is in the way on a regular BBC Micro. Altering PAGE manually won't change that. Try BBC Master 128 mode of jsbeeb: https://bbc.godbolt.org/?&model=Master Thanks that works! Out of interest how would you get it running on a Model B? I there a way to load it into memory, disable DFS and then run?...

Trying to run this in JSBeeb - I set PAGE to &E00 but I still get the message about setting PAGE. What am I doing wrong?

Rotating 3D Earth (Elk/Beeb)

Demonstration of fake spherical image mapping. Cross-platform demo. Runs on Acorn Electron and BBC Micro, Master 128. PAGE needs to be &E00 though! SPACE toggles between raster version and solid version. Real time calculation (using lookup tables obviously), not some animation frames read from disk ...

Seems like the Electron implementation mistimes the VSyncs slightly! One field is presented as 312 lines and the other as 313.
Which makes it possible to tell which PAL field you're on on the Electron :mrgreen:

Interlaced screens have a different frame period to non-interlaced (exactly 20ms), so the timer period needs to be adjusted accordingly!
Do you also happen to know the exact timing difference between even and odd fields in an interlaced PAL frame? (on an Electron, if that matters)
