Normalize not working

[yeqingxi]

I'm currently doing snap_to_sphere and for some reason when I normalize the interpolated coordinates, the results aren't normalized (as in they don't have a length of 1). So I'm still getting the edgy sphere instead of the smooth sphere. Any ideas why this is happening? I'm using the function normalize(vector).

Update: I tested the normalize function and it appears to be working, but the result I see is still the edgy planet.

are you sure you are saving the output of normalize function into another vector and using it?

So it should be smth like this vec4 interp_pos = interpolate(gl_TessCoord, pos_es_in[0], pos_es_in[1], pos_es_in[2]); then normalize interp_pos and save the result either to some other vector or overwrite interp_pos. Use interp_pos to calculate sphere_fs_in, view_pos_fs_in, normal_fs_in, pos_fs_in

Also be careful: interpolate returns vec4 which is a point but when you normalize you should normalize only vec3 part of the vec4 if that makes sense

Oh my god yeah it worked after I normalized only the vec3 part, I forgot that the 4th coordinate is set to 1.0 instead of 0.0 so it actually matters.
