bluatigro For shadow you need to check for objects that are between the point that is hit by the view ray and the light source. The code is similar to the code for checking if a sphere is hit by a view ray. If there's a object between that point and the light source the color of the sphere need to b...

A quick and dirty way to get win3.bas compiled. Add #lang "fblite" before defint a-z Change the line static shared internalfont (0 to 318) as short => { ..... into static shared internalfont (0 to 318) as short : data .... Remove the curly bracket at the end of the data block ( } ). Insert...

bluatigro A little lesson in finding a errors. The error is one which I have seen is one you made before. But let me try to help you how to find errors in your program. If you change the black background color into white what will happen. Thus pset( winx/2 + x , winy/2 - y ) ,0 into pset( winx/2 + x...

update : - try at shading error : - i get only 1 sphere whit a color background - i dont get shading To make the spheres visible replace Function tsphere.hit and Function winner_index with these two new routines. Function tsphere.hit( ray As tray ) As Double Dim As t3d o , d , s o = ray.origin d = ...

Thorbenn In FB the result of x1 = (i / Period) * Period is equal to i the calculation is not stored in between calculations, to get the result you want add INT to floor the division. x1 = (i / Period) * Period ==> x1 =INT (i / Period) * Period y1 = (j / Period)*Period ==> y1 = INT(j / Period)*Period...

bluatigro You dusted of your old ray casting program, you have probely mist my last posting in http://www.freebasic.net/forum/posting.php?mode=reply&f=3&t=22506 . (at the bottom) I have incorporated my version of the function ray named ray_new and altered the program a bit, give it a try. Th...

It's not as simple as the original problem with lower/upper case characters and it doesn't seem to be a problem with movegen function as latest version is perfect on perft for the following position as far as i tested it (to d = 7) 8/PPP4k/8/8/8/8/4Kppp/8 w - - 0 1 I'm wondering if it is related to...

Here is a newer version of Nomega (work in progress). Will compile with GCC. Changed the test for castling, the simple test are done first then the more complicated test like incheck and attack. If the simple tests trigger a break off the slower test aren't executed resulting in a small speedup. Inc...

Some tournament results with Nomega compiled with GCC -O max and good old Numpty_DD. 100 games 40 moves / 5 min (repeating) Nomega 55 wins and Numpty_DD 24 wins and 21 games ended in a draw. 400 games 60 moves / 1 min (repeating) Nomega 232 wins and Numpty_DD 86 wins and 82 draws. In general the mos...

As of January 2014, the largest known prime number is 257,885,161 − 1,[1] a number with 17,425,170 digits. http://en.wikipedia.org/wiki/Largest_known_prime_number That should be 2^257,885,161 − 1 Hi frisian, I'm home now and anxious to test your code. If possible can you help walk me through the in...

I have run a tournament with Nomega (GCC compiled) against Numpty_DD. Needless to say the Numpty_DD lost most of the time. I had 1 forfeit on time by Nomega, I was able to find out that it was caused by the following code in computer_move. if fmove(depth) = 100 then 'score = if 50 move rule is tripp...

I got a GCC compiled version running under Arena. In CommandLoop remove (or comment out) the following line SendCommand ("feature done=1") Ok Nomega would work but as it dropped out of the opening book (after 3 moves) it would again stop working. Freebasic is not very strict about array bo...

There is the possibility that the result is incorrect but I have tested the method with smaller numbers that GMP/MPIR could multiply. The result where equal therefore the method used should give a correct answer. But only a straight forward multiply will give a answer on the question of result is th...
