    Description

    -

    The glutWireTeapot and - glutSolidTeapot functions render a teapot of the desired size, - centered at the origin. This is the famous OpenGL teapot [add - reference].

    The glutWireTeapot and glutSolidTeapot functions +render a teapot of the desired size, centered at the origin. This is the +famous teapot created by Martin Newell. The other functions render the +teacup and teaspoon he used in the table scene figure in his PhD thesis. +Vertex data retrieved from: ftp://ftp.funet.fi/pub/sci/graphics/packages/objects/teasetorig.gz.

    Bugs

    OpenGL's default glFrontFace state assumes that front facing polygons (for the purpose of face culling) have vertices that wind -counter clockwise when projected into window space. This teapot is -rendered with its front facing polygon vertices winding clockwise. For -OpenGL's default back face culling to work, you should use:

    +counter clockwise when projected into window space. This teapot, teacup +and teaspoon are rendered with their front facing polygon vertices +winding clockwise. For OpenGL's default back face culling to work, you +should use:

      glFrontFace(GL_CW);
      glutSolidTeapot(size);
      glFrontFace(GL_CCW);

    -

    Both these bugs reflect issues in the original aux toolkit's teapot -rendering routines (GLUT used the same teapot rendering routine).

    +

    Both these bugs reflect issues in the original teaset's vertex data +(and are thus present in GLUT too).

    Changes From GLUT

    -

    None that we know of.

    +

    GLUT only has the teapot and misses the rest of the teaset.
