OpenGL -- Hex Sphere - Icosahedron

[Bert Mariani]

Hello Mahmoud et ALL

Attached:

     Hex_Sphere.ring

It is an example of UsingOpenGL

It draws a  Hex Sphere - Icosahedron - Animation

You can use the Mouse click and move to rotate the sphere while it is in motion.

# Complete 20-Face Icosahedron - verified correct topology
# All 30 edges appear exactly twice, all 12 vertices have valence 5

Thanks Mahmoud

Added 2 more

     Penta_Sphere.ring

     Octagon_Sphere.ring

They use the libraries

     "opengl21lib.ring"
     "freeglut.ring"-

Penta      -- Dodecahedron Sphere -  5 sided Pentagons on a Ghost Wireframe Sphere

Octagon -- Octahedron Sphere  - 4 sided  Squares on a Ghost Wireframe Sphere

Hello Mahmound

Another one using opengl21lib.ring  and  freeglut.ring

     SinCos_Surface.ring

Surface Plot:  z = sin(x) * cos(y)

Looks like an egg carton.

Colors depend on resulting Z value.

It scales according to the Window Re-Sizing

It can be Rotated in all directions  --even Upside-Down

=====================

Hello Mahmoud, Azzeddine et ALL

 Using opengl21lib.ring  and  freeglut.ring

Added Mug Rotation

    Mug_PointCloud_3D.ring

Azzeddine

     I have a bug I can't seem to figure out.

     Y-axis rotation ~ 225 degrees, Mug Handle jumps to Front ??

     X and Z set to No Rotation.

Does it happen on your version of Mug Rotation with Tensors ?

===========================

#  DEBUG AXIS CHECKBOXES (click OR keyboard to toggle):
#    Click checkbox  -- toggle that axis on/off independently
#    X key  -- spin X axis only
#    Y key  -- spin Y axis only  (default)
#    Z key  -- spin Z axis only
#    A key  -- All axes
#    S key  -- Stop / pause
#    ESC    -- Quit

=============================
