344610e24b Actually use the calculated position in the layer list. This prevents the use of glDepthMask(). Clean up the code some. 2003-08-22 16:58:01 +00:00

d56b961c47 A patch from Frederic Bouvier which performs z-buffer ordering of the cloud layers to prevent transparency problems with other (se mi) transparent objects. Good work Frederic! 2003-08-22 08:07:21 +00:00

5628c85b51 Frederic Bouvier: 
This patch was inspired by Norman. Otherwise there is a segfault on Linux because the global variable tries to access OGL before a valid context is initialized.

110e01a861 Remove extraneous/unneeded dependencies on glut. SimGear should no longer

578e774778 Remove "glut" dependency. 
- SkyContext.[ch]pp needs to query the window size, but apparently doesn't
  do anything with it.  We can hard wire a size and the cloud code seems to
  behave fine.

- SkyLight.[ch]pp depends on glut_shapes so I copied over the code so it
  can access those routines locally.  (The routines that are used are
  simply combining calls to libGLU.a

73a4994cac Norman Vine: 
Note that SSG and OpenGL use different representations
of Matrices.

1) SSG is row major and OpenGL is column major

2) SSG uses a Z is up whereas conventionally OpenGL uses
   Z is pointing into the screen
   ie this just requires swapping the Y and the Z axis < columns >
   and negating the new Y column

3) Now since SSG eventually calls OpenGL SSG must do this
   for us behind the scenes or else things just wouldn't work
   so inorder to get Clouds3D to render in the proper location
   we should just need to use the Matrix that SSG uses for a Camera
   Matrix and pass this directly to the Clouds3D Camers

4c78e887e1 Jim Wilson: 
This update adds the ability to do multiple texture transforms (Steve B. thinks supporting them at the plib level would be inefficient, which is probably true).

Removed units (e.g. "_m") from texture translation property and variable names since the texture translation values are dimensionless.

Added the ability to specify a scroll factor for stepped texture animation that needs to scroll smoothly when approaching the step interval (e.g. odometer movement).
