What is glutSolidSphere?
What is glutSolidSphere?
Description. The glutSolidSphere() function draws a shaded sphere centered at the origin. The surface is created from quadrangles (except for triangles as degenerate quads at the poles) in a longitude/latitude pattern. The equatorial great circle lies in the xy-plane and is centered on the origin.
What is gluSphere?
The gluSphere function draws a sphere of the given radius centered around the origin. The sphere is subdivided around the z-axis into slices and along the z-axis into stacks (similar to lines of longitude and latitude). Otherwise, they point toward the center of the sphere.
How do you get a sphere in glut?
The solution is simply to change the viewing frustum and radius of the sphere. For instance, gluOrtho2D(-5.0, 5.0, -5.0, 5.0); glutSolidSphere(5.0, 20, 20);
What is glutTimerFunc?
glutTimerFunc registers the timer callback func to be triggered in at least msecs milliseconds. The number of milliseconds is a lower bound on the time before the callback is generated. GLUT attempts to deliver the timer callback as soon as possible after the expiration of the callback’s time interval.
How do you draw a sphere in OpenGL C++?
In order to draw the surface of a sphere in OpenGL, you must triangulate adjacent vertices to form polygons. It is possible to use a single triangle strip to render the whole sphere. However, if the shared vertices have different normals or texture coordinates, then a single triangle strip cannot be used.
What is GLUQuadric?
GLUQuadric() Creates a new GLU quadric object for use. Method Summary. protected void. cylinder(double baseRadius, double topRadius, double height, int slices, int stacks)
How do you draw a ball in OpenGL?
What is a quad in OpenGL?
An OpenGL® quadrilateral, or quad, in computer programming and graphics is a three-dimensional (3D) shape, also called a polygon, that has four sides and four points. This can be done to have a static user interface overlaid on top of a 3D scene or to emulate 2D graphics with OpenGL®.
How do you draw a sphere in OpenGL?
What is glutDisplayFunc?
glutDisplayFunc sets the display callback for the current window. When GLUT determines that the normal plane for the window needs to be redisplayed, the display callback for the window is called. GLUT determines when the display callback should be triggered based on the window’s redisplay state.
How many faces has a sphere?
one
A face is a flat or curved surface on a 3D shape. For example a cube has six faces, a cylinder has three and a sphere has just one.
What does glutsolidcylinder() do?
Divisions along z axis. glutSolidCylinder()draws a shaded cylinder, the center of whose base is at the origin and whose axis is along the positive z axis. See also: glutWireCylinder()
What does glutsolidcone() do?
The glutSolidCone()function draws a shaded cone with a base in the xy-plane, oriented in the positive z direction. Note: The number of polygons representing the conical surface is proportional to (slices*stacks).
How does the glusphere function work?
The gluSphere function draws a sphere of the given radius centered around the origin. The sphere is subdivided around the z-axis into slices and along the z-axis into stacks (similar to lines of longitude and latitude).
What is Glu_outside in a sphere?
The sphere is subdivided around the z-axis into slices and along the z-axis into stacks (similar to lines of longitude and latitude). If the orientation is set to GLU_OUTSIDE (with gluQuadricOrientation ), any normals generated point away from the center of the sphere. Otherwise, they point toward the center of the sphere.
