Hi,
Due to the bad weather in Belgium I found some time to work further on the
website buttons macro I started some time ago.
The macro can render now a set of buttons for a website using pov animation
(and a few days of patience on 512*384)
By the way: is there any way to change the name of the bmp output file in
the during rendering? output is now produced by the animation in
webbuttons00.bmp,webbuttons01.bmp etc. It would be more convenient for later
use of render output if I could name them something like button_<text inside
button>_blue_normalstate.bmp.
There is 2 versions pressed state with lights shining & normal both
rendered with +-14 lights behind the text. Problem is that they take a long
time to render. Is there any way to speed up rendering with this amount of
lights.
I tried one version with radiosity with an emitting text behind the black
text, but I'm not really happy with the result. The way the light shines on
the side of the button seems unnatural to me. I like the backlight inside
the button though.
I don't know enough of radiosity I to find out how to improve it. Any
suggestions would be appreciated.
Radiosity settings are :
global_settings {
max_trace_level 100
assumed_gamma 1.25
#if (Radiosity)
radiosity {
pretrace_start 0.04 // start pretrace at this size
pretrace_end 0.002 // end pretrace at this size
count 250 // higher -> higher quality
(1..1600) [35]
nearest_count 10 // higher -> higher quality
(1..10) [5]
error_bound 2 // higher -> smoother, less
accurate [1.8]
recursion_limit 3 // how much interreflections are
calculated (1..5+) [3]
low_error_factor .5 // reduce error_bound during
last pretrace step
gray_threshold 0.0 // increase for weakening colors
(0..1) [0]
minimum_reuse 0.015 // reuse of old radiosity
samples [0.015]
brightness 0.4 // brightness of radiosity
effects (0..1) [1]
adc_bailout 0.01/2
//normal on // take surface normals into
account [off]
//media on // take media into account [off]
//save_file "file_name" // save radiosity data
//load_file "file_name" // load saved radiosity data
//always_sample off // turn sampling in final trace
off [on]
//max_sample 1.0 // maximum brightness of samples
}
#else
