Hello
With the code:
Code :glTexImage3D(GL_TEXTURE_2D_ARRAY_EXT,0,GL_LUMINANCE8,512,512,2,0,GL_LUMINANCE,GL_UNSIGNED_BYTE,tex2Darray);
(tex2Darray pointing to a GLubyte array of the right dimension 512*512*2 bytes)
glGetError() gives the value 0x500 "GL_INVALID_ENUM"
Is there a problem with arrays of 2D texture with GL_LUMINANCE8?
Perhaps should I use glTexStorage3D() and glTexSubImage3D()? But what should be the "internalformat" of the first and the "format" and "type" of the second to accept GL_LUMINANCE8 texture?
Thanks
Cathy L.
