glutSolidTeapot(3GLUT) | GLUT | glutSolidTeapot(3GLUT) |
glutSolidTeapot, glutWireTeapot - render a solid or wireframe teapot respectively.
#include <GLUT/glut.h>
void glutSolidTeapot(GLdouble size); void glutWireTeapot(GLdouble size);
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.
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:
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).
