when i'm using shaders instead of fixed functionality to create projective

you can see in the image below.

I belive i do something wrong about the texture matrix generation.
My vertex shader just calculates the texture coordinate for the given vertex by
using
the texture matrix 1:

Perhaps you have any tips according to my problem? Maybe i have missed a step

to the texture matrix generation?
1) TexGen doesn't modify the texture matrix but generates texture coordinates.
2) TexGen is a fixed-function functionality so you'll have to generate the texture
coordinates yourself in the vertex shader.
