- .SH NAME
- glutSolidTeapot, glutWireTeapot - render a solid or wireframe teapot respectively.
- .SH SYNTAX
- .nf
- .LP
- void glutSolidTeapot(GLdouble size);
- void glutWireTeapot(GLdouble size);
- .fi
- .SH ARGUMENTS
- .IP fIsizefP 1i
- Relative size of the teapot.
- .SH DESCRIPTION
- glutSolidTeapot and glutWireTeapot render a solid or wireframe
- teapot respectively. Both surface normals and texture coordinates for the
- teapot are generated. The teapot is generated with OpenGL evaluators.
- .SH BUGS
- The teapot is greatly over-tesselated; it renders way too slow.
-
- 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:
- .nf
- .LP
- glFrontFace(GL_CW);
- glutSolidTeapot(size);
- glFrontFace(GL_CCW);
- .fi
- .LP
- Both these bugs reflect issues in the original aux toolkit's
- teapot rendering routines (GLUT used the same teapot rendering routine).
