howto render 3d image from raytracing dataset

[KingGuru]

Hi..
I have a raw dataset that I'm supposed to raytrace with cuda to make 3d images.. I have a quite decent idea on how to ray trace.. but I can't figure out how to get make the image using openGL

any idea's on how to do this.. as far as I can see from some forums, ppl suggest PBO.. but how do I get the data into a PBO, and then how do I render it?

the easiest way is probably using glTexSubImage2D
Just create a texture of an appropriate size and then just update the data as you wish, works great.
Here is what i use.
glTexSubImage2D(GL_TEXTURE_2D,0,0,y-rows,512,rows,GL_RGB,GL_FLOAT,&data[0]);
where y is the last row i am on and rows is how many rows per batch i am updating.
