[vtkusers] Help using vtkOpenglTexture with OpenGl

[Yiasemis]

Hello,

 

I am trying to use some dicom images I read with VTK into some OpenGl code I
write so I can implement some pixel shading on them.

1) How can I use the glBindTexture with an object of type vtkOpenGl ?

I tried something with  a method ResampleToPowerOfTwo in vtkOpenGLTexture
but looks like is not the case. 

Or at least I cant figure whats the *dptr part of

unsigned char* vtkOpenGLTexture::ResampleToPowerOfTwo (  int &  xsize, int &
ysize, unsigned char *  dptr, int  bpp )  [protected]

 

Thanks a lot :)
