• demo Commodore 64 Soiled Legacy by Resource [web]
• Yesterday, I met again with 2 greek CPC sceners from Dirty Minds and decided to show them some of my latest favorite C64 demos (This one, Insomnia and Cycle). There comments were very funny..
  
  They loved this one the most, perhaps because of more effects and little details. The mask blowed them away of course (Our old member Morbid, said something like "Tell me now I am on Candid camera or something?!" and our main coder Antitec wondered "Why are we so many light years back on CPC?".
  
  The funniest thing was what Morbid had said about the messy effect on the screenshot above "That must be her vagina =)"
  
  It's always interesting showing C64 demos to CPC sceners and make them wondering about what the possibilities are..

• I don't give a fuck about justifying the attitude. Go fuck yourself, I have been coding on a CPC and now on a C64 :)

• >integer routines VS floating point
  
  Well,. I hate when people are saying "We don't need integer today because FPU is preety fast". It's too general. What does this mean? That I can write a simple 2d sprite game with floating point?!? I don't think it's faster..
  
  It might be only faster or more convenient to do than fixed point perhaps or cases where you have to switch from floating point to integer and back many times. I don't really know, for I have not made some tests yet on my Athlon. But I think that everything has it's use..
  
  For example, I believe that especially some 2d effects could be still done with integer much faster. When I watch some software demos in older machines and try to understand why are they going so slow, I can't think anything else rather than the fact that FPU was used on every simple routine (no matter if some can go shitty fast with integer for sure), just like taking the equations for the effects and using them as they are, porting them without trying to optimize anything. When it works (and smooth enough with modern computers), people are so happy and do not care. And then they say excuses like "Integer is slower than FPU today" while it depends on the case..
  
  Of course, FPU is more suitable on 3d gfx, it's harder for me to figure out how to use pure integer on a 3d engine especially on a very big and detailed one (perhaps it's easier on a simple 3d object show) without fucking up with everything. I started coding a simple 3d dot object rotator and I am simply bored to mess with my code to make it work with pure integer (oneday I tried badly, the dots movement was so jerky and sometimes wrong :P). However it has been done on the past for sure (with object shows on 486 demos). TeXeL even claimed to have found ways to do raytracing with pure integer, pitty he hasn't released anything :(
  
  Perhaps FPU is ok for 3d vector maths, to move/rotate vertices and stuff, which are not very much. Then a triangle rasterizer could be better done by integer. 2d effects can be easilly done with integer, precalculated tables of sines and fast. For example a 2d distorter, I just don't know however about a filtered one (The one at the Orange demo Ibiza Experience, looks really great, however I can finally watch it fast now!)
  
  Today I can analyze when a demo runs slow, think of the effect and imagine what the coder might be doing wrong, in some cases. And I discover that thing: Coders using FPU (sometimes even SIN, SQRT and such stuff instead of making tables) where it should be avoided..
  
  Actually I wanted to start with some FPU assembly (might be needed for 4kb OpenGL intros), but I hate the stack. I just don't know when I will find the mood to mess with it again and finally understand it :P
  
  Mmm,. I shouldn't be writting that much...
  
  Some more stuff now would be, I didn't want to blame anyone with these stuff rater than say my opinion, so Quisten and the others can do what they wish and I like that they choose what they love to code (Who knows,. even me with that Athlon 2600+ I have now at home, might be seduced to take the "not care" way :)
  
  Also, thanks for that link of the fast 3d engine, I will check it now..

• demo Windows Shadows by Scarab Corpse [web]
• It's not as slow as the other software stuff (running decent even in my Pentium2 at 233Mhz) and a nice watch yesterday that I watched again..

• Surprisingly I see a lot of software demos at TG (3 or so and there was 1 more in Birdie I think), how rare, however I didn't liked that much any of them. At least 2 of them are slow however (perhaps they won't be on my new Athlon 2600+ but in general they are) and then claim that software is hardcore :)
