Hi All,
I’m a bit confusing about loading some of my OBJ files.
I’m programming to OpenGLES 1.1, so I use glDrawElements to render my models.
However, to specify the vertex, normals and texture coordinates I use :
glVertexPointer, glNormalPointer and glTexCoordPointer.
But using this functions, I assume that I need a relation between vertex - normal - texture coordinate, of one to one.
But, some of my models, they have faces that share the same vertex but with different texture coordinates.
IS this normal to happen ? What should I do ? Duplicate the vertex ?
Thanks in Advance,
Victor
