I'm not English, so sorry for my grammar if I am wrong. I hope you'll understand me (I am new on this forum, so if I put this thread in the wrong place please correct me).

I know Blender for three years I think and I love making beautiful pictures with sunlights and shadows. Now I am curious about making movies. I saw 'camera tracking' and it looked very awesome! So I started watching tutorials and things, but now I have a little problem with the textures and I don't know how to solve it. :confused: I made a small video walking in my room and I managed to put a minecraft flower on the ground. Everything is going fine, but when I render it the flower is completely white. In texture-mode I can see the blue and green texture... Can anyone help me?

Thanks! ]]>

This library could be used to calculate fresnel coefficients (they are often complex numbers when we have

total internal reflection or non zero extinction coefficents in the index of refraction )

In the file,a complex number is a structure with

components

re = real part

im = imaginary part

phase = the phase in the polar form

r = the amplitude (absolute value) in the polar form

The functions are the following:

Note that the result (s) of a function is the output value(s) argument of the function.

createc (create a complex number with 2 float numbers as arguments)

addc add 2 complx numbers

subc subtract 2 complex numbers

mulc multiply 2 complex numbers

mulcf multiply a complex number and a float number

divc divide 2 complex numbers

recc reciprocal of a complex number

sgn signature of a float number

powintc integer power of a complex number

sqrtc square root of a complex number.There are 2 solutions.

expc exponent of complex number (exp(z))

conj conjugate of a complex number

negc as zero - z

sinc sine of a complex number

cosc cosine of a complex number

logc natural log of a complex number

asinc arcsine of a complex number

acosc arccosine of a complex number
