Title: OPTIMALIZATON
Post by: shaldan on October 14, 2005, 01:31:31 PM
I saw MACRO CFLT here in functions like glVertex3f, CFLT(-1.0), CFLT(1.0), CFLT(0.0)
and I wondered if there is a speed (or storage) difference between using this macro or simply using declared variable in such functions.

for examples:

.data
Val1         dd 1.0
Valm1                 dd -1.0
.code
invoke glVertex3f,Valm1,Val1,Val1

thanks

p.s. thanks GOD and Randall Hyde for his books :)

No speed difference but same floating points will be duplicated when using the macro.

thank you very much for the answer ....
it is amazing what can be done with openGl by one man ..... (just watching your demos :)))
How many years? :) are needed to achieve such mastery ? I am new to openGl and little experienced in MASM....
and 1kb demo is black magic stuff for me :)
