SuperBASIC and SMSQ/E SBASIC is the best BASIC variation, BBC Basic as OK, but it has some features that I d not like.



Yes, I agree with this, SuperBasic is the best, I tasted a little BBC basic on my Z88, it's not so good (clumsy syntax). But you must at least have TK2 added and also if you ...

Let me tell you the whole story : I first programmed my perspective transform in FORTH for a 80386 PC with a VGA (640x480) graphic card. I join here my initial code :

My first goal was to plot a single true perspective view of a 3D wire frame not using floating point nor ...

Hi

I like the Forth language but have limited time to be proficient in it.

I used like using Brouhabouha Forth, would your 3D Forth file work in Brouhabouha?


I compared essentially ComputerOne FORTH and Digital Precision SupperFORTH, by porting on both some serious programs like a Conway's ...

Hi Polka,
You said: << the AVION connection data was compacted by the word XA that will just after the first connection -1 X automatically loop from point 2 to point 15 and then continues with 9 X 16 X etc. >> I am afraid I don't read FORTH code, so this explanation is rather abstruce !

To make a point on my method compared with the classic (trigonometric) method :

In both, you have to consider the object (or scene) reference and the camera reference.

In the classic method you compute a 3D rotation of the scene to become parallel to the camera reference ; by multiplying 3 ...

Impressive!

I'm wondering how fast in relation to actual speed, is that GIF?

Cheers,
Norm.


In the old thread that I showed the link above, beginning page 3, I measured the speed, comparing the same program running under ComputerOne FORTH and Digital Precision SupperFORTH. On a BBQL with 128k ...

Hi !

At the end of the PERSPECTIVE.FTH source file you have three MESH type words that contain the data for a SQUARE , a CUBE and an AVION (the airplane). These data words are compiled by the four words compiled just before : MESH , C , X , and END-MESH.

the MESH word creates a mesh data structure ...

HI !
I showed here some time ago :
viewtopic.php?f=3&t=3238&p=33721&hilit= ... ive#p33721
a way to code TRUE perspective tranform (not plain axonometric) without any trigonometry, thus even possible only with integer arithmetics. Here an example of the result :

I did this with the ...

Me too, I am sad having missed this year and hope for the next meeting. My car is repaired.
BYE

Hi all !
Jedi will unfortunately not attend. Yesterday morning, I was driving to Dormagen, when my car had a serious harware bug, and I had to stop immediately. As I was already in Germany but not more than 20Km (but in the middle of nowhere), I passed the rest of the (rainy) day to organize its ...
