Thanks for the hint D, I now have a picture of my son rotating on the cube. The routine to print the sprites is now a combination of asm and fpasm. With no gaming code yet it will run at approx. 55fps. Not bad but I was hoping for more. It is now to big to add here as a code snippet (approx 40000 chars) so I will look for another method of distribution.

DDRM would know how the following technique could be done in BBC basic, or perhaps Richard would know.
1) offset a secondary window for the size of image you want to create
2) capture the image in a sprite
3) post the sprite on the main display window
4) clear the offset window and repeat
This would create flicker free animation and would allow redraws to be done off screen
Also, this would minimize memory use because you are using the same sprite for image capture/ transfer/ display

Thanks Michael,
I am sure for a man moving across the screen that would work, but the 55fps is for the whole screen rendering a 3d landscape like most modern games. My calculations work out that this will drop to 40fps with game play code. The sprite in question is just one of many used to create the landscape, and using the four corners as nodes can be skewed to create full 3d with depth perception. Originally my challenge to myself was to learn asm and write a 3d game, it's going OK so far. If I moved to a modern laptop this would aid speed as mine currently is a measly 1.9Ghz.
Regards Ric

I think I have found an easy way to post code by using Wikisend, if it works I will post the code so far. The ball now has a globe skin on it.

That's pretty cool. You able to place more objects on the screen and put them at depth?

I can not yet put multiple objects but that is only because I have only loaded the nodes for one. The depth I am working on, it is a simple calculation involving the z vector and then factor X and y. I will post on Wikisend tonight.

Evening all. I was going to post the code on wikisend, but I cannot get the upload to work. I have given in!!! If anyone can tell me how to post the code some how, somewhere I will do so. Or I can email it.

Hi Ric,
I've never used Wikisend, but might Github be a suitable option? I've used that in association with a MOOC course I did, and it seemed OK.
https://github.com/
I think the Wiggio forum and its file storage are still functional: you'll need to sign up to upload, but it's free:
https://wiggio.com/
Richard has now set up what looks something like a mirror of the old Yahoo forum on Groups.io:
https://groups.io/g/bb4w
I haven't really got to grips with that forum yet, but it looks like once you have signed in you have access to a file storage area, though my guess is that that would only be accessible to others who were members.
I'd certainly be interested to see what you've done - both in terms of code and function.
Best wishes,
D

Hi Wildmooer,
If you are relatively new to programming you may find Ric's code a bit intimidating - most of it is in assembler, I think!
It might be worth playing with the Direct3D library supplied with with BB4W -even that is tricky, but simple things (like a mapped rotating sphere!) are relatively straightforward - indeed a working demo is supplied (world.bbc, in the graphics folder of the examples).
Best wishes,
D

Cheers D
I will have a look at these tonight.
You are correct in assuming most of the code is in assembler, with only the setting of parameters in basic. I have loosely annotated it , but even so unless you are very au fait with assembler it will look like gobbledegook😋

Hello again,
I have had a go at all the suggested methods of uploading my code, but without sounding to negative I feel like a blind man playing snooker. I have failed with every attempt. And I am thoroughly brassed off. I will keep updating where I am up to and post results via video on youtube. but unless someone is prepared to ring me up and walk me through some form of file sharing I am giving up. Sorry to those who are following, but I really cant get any of the methods to work.

Dropbox is supposedly very good. And it has some high profile programmers behind it.
Actually Richard was the one to recommend it to me so here is the link:
https://www.dropbox.com/
I have it but have no major projects done to use it yet.
