Hello to you every chaoscopers
Here's my opinion after testing the enhanced preview. Many thanks Nicolas!
First reaction: Yeppee yeppee yeppee!! Very interesting features ;-).
- Solid mode:
It's the first time I can see this, wonderful! Exactlty what I hoped
from you Nicolas :-) This time you can tell it's a real preview in solid
mode! No transparency nor gamma settings but a preview with an
astounding accuracy, except for lights (1 suspect one more in preview
but maybe is it the lack of shadows) Of course I understand, shadows are
very time consuming. Moving the mouse is like watching a cartoon. I had
a bug when hight zooming with your first exe but I can't reproduce it
with the new one. Good no? ;-)
- B&W modes: Didn't notice any strange behavior. Beautiful!
- Colored modes: Beautiful too but here there is a problem. It can be
very beautiful but I don't have the same colors I have with rendering
(?). Colors are differents. Like if the gradient's arithmetic would'nt
be the same in both cases. Just try any kind with the standard
gradients: youl'll see the first calculations but if you click to see
the enhanced preview, you won't see anything or something very dark. Try
to render the picture... surprise, it appears. Easy to see this strange
behavior: just change the black angle gradient by a red one for
instance, press F3, see, and click on view, you'll see what I mean. It's
not the same color scheme...
263524 Ko for a huge zoom, more than 90 ;-). Depends of parameters in
options file. Even returning to a 'normal' view by a new F3, the memory
consumption stays hight. To free the memory I need to launch an other
rendering mode. Sometimes a peak at more than 400 Mo. Launching an other
rendering mode reallocates the minimum required memory.
My options file have all values multiplied by 10 and even in solid mode
the animation stays almost smooth. Not any problem with other modes,
very smooth, not any interruption between frames...
For a normal usage, it could be useful to have a sign somewhere showing
the machine is in calculations instead watching the task manager ;-) I
know it's a test release...
I appreciate the iteration correction on zoom feature, great! Fast and
efficient!
So what could I tell more? Nothing. Just great !! Just this color
problems for me.
MEMORY ALLOCATION
With standard option file:
-Launching 4 168 Ko
Icon 640 x 480:
- Gaz: 14 312 Ko
- Liquid: 15 832 Ko
- Light: 18 512 Ko
- Plasma: 19 804 Ko
- Solid: 16088 Ko
Option file with all values multiplied by 10
- Launching 4 168 Ko
Icon 640 x 480 (the same, joined)
- Gaz: 39 392 Ko
- Liquid: 40 760 Ko
- Light: 48 672 Ko
- Plasma: 49 236 Ko
- Solid: 40 968 Ko
Option file with all values multiplied by 100
- Launching: 4 160 Ko
Still the same icon
- Gaz: 250 908 Ko
- Liquid: 127 724 Ko
- Light: 275 284 Ko
Bug when passing from light to plasma: violation access in module
atioglxx.dll (read of adress 000000) and an other with "external
exception EEFFACE"
The program seems to return to normal state after clicking OK
- Plasma: 275 480 Ko
- Solid: 287 080 Ko not a very smooth animation of course... after
relaunching: 129 824 Ko only! Strange no? 251 936 Ko after zooming to 4.
All these values can vary a little bit, around 100 Ko more or less.
Don't know why.
Have FUN !!! Oh yes you can!
