Greetings, with the help from lc_overlord I've added texturing to the heightmap tutorial. Now I would like to add the parralax maping to the same code.
I have found and example of parralax mapping here http://www.codesampler.com/usersrc/usersrc_5.htm
Now I succesfully added the variables and functions from the parallax project to Nehes tutorial but am havin some trouble makin it work.
I have tried adding the texture initialization to the RenderHeightmap function where the texturing went on before. However the result is not very satisfying and quite slow.
I am not sure where to best place the folowing segment of code
glUseProgramObjectARB( g_programObj );
glInterleavedArrays( GL_T2F_C3F_V3F, 0, g_quadVertices );
glDrawArrays( GL_QUADS, 0, 4 );
glUseProgramObjectARB( NULL );
which is in the render function of the original tutorial.
My project is here http://www.megaupload.com/?d=AADG2YQZ
If anybody has any ideas I would be gratefull, now i need to get some shuteye :)
p.s the heightmap terrain is the other .raw file in the data folder, Im curently testing it ona a flat terrain
