I would like to use gluBuild3DMipmap but am having issues with the glu32.dll saying there is no gluBuild3DMipmap and this is with the 1.3 version from http://www.geocities.com/vmelkon/glu.html
So what can I do to get this function to work? If I use wglGetProc address where is the extension file so I can see what I need to use/add?
Second question is ok just use hardware mipmapping. Well is this the correct way to use/setup mipmapping with either method?
glGenTextures(1, texture); glBindTexture(GL_TEXTURE_3D, *texture); glTexParameteri(GL_TEXTURE_3D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_3D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_3D, GL_TEXTURE_WRAP_S, GL_REPEAT); glTexParameteri(GL_TEXTURE_3D, GL_TEXTURE_WRAP_T, GL_REPEAT); glTexParameteri(GL_TEXTURE_3D, GL_TEXTURE_WRAP_R, GL_REPEAT); //or if using GL_GENERATE_MIPMAP uncomment the next line //glTexParameteri(GL_TEXTURE_3D, GL_GENERATE_MIPMAP, true); glTexImage3D(GL_TEXTURE_3D, 0, imageTypeInternal, imageWidth, imageHeight, 0, imageTypeFormat, GL_UNSIGNED_BYTE, imageData); glGenerateMipmapEXT(GL_TEXTURE_3D);
Shouldn’t I only have to call the mipmap functions glGenereateMipmapEXT() or GL_GENERATE_MIPMAP only once when I setup the textures? I am not doing any RTT with it… As of right now it doesn’t look like the textures are being mipmapped and I am using this with the new EXT_texture_array extension. Possible error? Thanks
