Találtam egy szórakoztató videót a sugárkövetésről Basicben egy CPC-n. Egy DevilMarkus becenevű CPC-guru 2021-ben készült munkáiról van szó.

Aztán kerestem itt egy régi szavas témát, ami ide hozott ebbe a magyar témába.

Kipróbáltam a rövid Basic listákat a CPCemu-n, és lassan rajzolnak egy jelenetet.... Még mindig nem tanulmányoztam őket, hogy megtaláljam, hogyan működnek.

I have found a fun video related to ray-tracing in Basic on a CPC. It is about some works made in 2021 by a CPC guru nicknamed DevilMarkus

Then, I have search here an old thread with the word, that has brought me here to this Hungarian topic.

I have tried the short Basic listings on the CPCemu and they slowly draw a scene.... I still have not studied them to find how they work.

A listákon nem látok problémát, de nem alkalmasak a ZZZIP-re, mert lebegőpontos számokat használnak.


I see no problems on the listings, but they are not apt for ZZZIP, because they use floating point numbers.

Sorry, only in English:

My first EP version. It was easy to convert, but it needs some adjustments on resolutions and colours.

I didn't know that on CPC(and on MSX?) you can manage at the same time a matrix and a numeric variable with the very same name. T and T(n), for example, are different variables.... It is annoying. I converted T to TT, but it not always has worked because then a TT var was also used... I was forced to convert this TT to some other pair of letters not used...

I suspect that this listing originally comes from MSX, because Microsoft Basic ignores third and forward letters of the name of a variable. And also for the original graphics mode used, SCREEN 8,0.
