This is the 8th look at writing a tool that can handle most syntax level conversions from Blitz BASIC into PlayBasic compatible syntax.
In this episode we take a quick look at the results of the optimization pass applies to the freshly converted BlitzBASIC code. In this video; the code is set up to perform the optimization pass upon pressing the enter key. We test various source codes from one with than less than a hundred lines through to the Xlnt GUI source code which is over 8500 lines and it barely impacts the frame rate.
Hello, I have been working on this ported code for 2 months. this is version 1, with only enough active menu's to re-create the cover of the book.
the original book is called "Amiga 3D Graphic Programming in BASIC" published in 1989.
i purchased the book in 1990 when i owned an Amiga 500. i never got around to coding the book back then, but over the last several years i have studied up on 3D, so thought i would give it a try.
well, success. i got the ray tracing up and running, the main scene (with default objects to re-create book cover) working, and the editor is active enough to see the objects from the main scene.
i will get the editor and main scene running more complete in version 2. i did notice it will be a learning curve to use this program, because of the way it is set up...
to port the code took time because i needed to use another 5 books for reference to know the commands and libraries etc in this 3D book.
the other books i referenced are:
> AmigaBASIC Inside and Out
> Amiga Graphics Inside & Out
> AMIGA ROM KERNAL REFERENCE MANUAL: Libraries & Devices
> AMIGA ROM KERNAL REFERENCE MANUAL: Includes & Autodocs
> Amiga Machine Language
i am sure glad i had all these books from the old fashioned days.
also the book had obsolete sections of code that are not relevant to modern day computers.
to get some scope of old computers vs new computers, the book said to allow up to 3 days to render if using full res (640 * 400) or 1 day at half res. well... my computer rendered at 1600 * 960 and took 22 seconds, lol.
NOTE: to look at the 'editor' to see the scene objects in it, select it from the drop down menu : Editor > Start Editor.
I found this old optimization source code on my hard drive that does bump mapping in software. The only problem is, that it's written in another BASIC language, so I decided to port it PlayBasic and see how it'd perform in PlayBasic V1,65...
Runs fine
Here's a video (cam capture) of the vampire sprite and image conversion demo. It's using the palette mapping feature to covert 16bit image data into 32bit ARGB image data
