basically .. if i try to use assert( function() == 0.01 ) the assertion fails .. if i assign ff2 = 0.01; and then assert( function() == ff2 ) the assertion passes
<bitbasher>
and if i test with echo( ff2 == 0.001 ) i get false
<bitbasher>
but .. for the case of the fraction 0.1 i do not need to assign ff1=0.1 because assert( function() == 0.1 ) passes
<bitbasher>
and .. i tried to register my nick with the NickServ .. i get the message telling me an email was sent .. i get the email . .but the content of the email is "This message cannot be loaded at this time. Try again later."
<bitbasher>
but it never updates .. is the libera.chat service not supporting the nickserv properly or am i doing something wrong?

All I get is "Ignoring unknown function 'float_fraction'" because your code is incomplete, so I can't see what it's supposed to do.

guso78k My understanding of your sorting code is that it forces VBOs to be rebuilt for every camera change. Considering VBO building is pretty expensive already, that may be a showstopper.

ah .. i see .. i know about pastebin .. i will use it if i need to get into this problem again

teepee, the new render code shows the benchy much better. without sorting you will not see anything inside because of just misordered triangles.
<teepee>
"much better" sounds good
<teepee>
right now it's just random, and mostly bad for anything even slightly complex
<guso78k>
kintel: the code is not executed on each angle change, but only if the angle changed more than 60 degrees from previous evaluation. and the detla can even be increased to infinity, so only triangles are sorted with the angle when f is pressed
<guso78k>
teepee exactly, you can try to run the benchy with dev snapshor instead

hi again .. still having a problem comparing fractional values .. this code shows the problem - any insights welcome - https://bpa.st/OX5A

ok .. this is really bugging me now .. i found out my assertions where giving false positives .. i added more tests .. any insights as to why my numeric comparisons are failing would be good - https://bpa.st/AU6A

bitbasher: You are comparing floats for equality, that dose not work. Floats are somewhere around the expected value at best, somewhere completely off when you get out of the range they reliably support.
