Compile Togl with Visual C++ 6.0 (Part2)

2005-05-06T18:39:11Z

The function Togl_StereoFrustum:

void
Togl_StereoFrustum(GLfloat left, GLfloat right, GLfloat
bottom, GLfloat top, GLfloat near, GLfloat far, GLfloat
eyeDist, GLfloat eyeOffset)

gives the following error mesages, when compiled with
Visual C++ 6.0:

cl -DPACKAGE_NAME=\"Togl\" -
DPACKAGE_TARNAME=\"togl\" -
DPACKAGE_VERSION=\"1.7\" -
DPACKAGE_STRING=\"Togl\ 1.7\" -

(Translation of german error message:
Extension not corresponding to standard: 'near' is an out-
of-date keyword)

A workaround like the following works:

void
Togl_StereoFrustum(GLfloat left, GLfloat right, GLfloat
bottom, GLfloat top, GLfloat nearPlane, GLfloat farPlane,
GLfloat eyeDist, GLfloat eyeOffset)
{
GLfloat eyeShift = (eyeDist - nearPlane) * (eyeOffset /
eyeDist);

glFrustum(left + eyeShift, right + eyeShift, bottom,
top, nearPlane, farPlane);
glTranslatef(-eyeShift, 0, 0);
}

Compile Togl with Visual C++ 6.0

2005-05-06T18:23:44Z

To be able to compile Togl on Windows with both gcc as
well as Visual C++ 6.0 the following line in configure.in:

TEA_ADD_LIBS([-lopengl32 -lgdi32])

has to be changed to:

TEA_ADD_LIBS([opengl32.lib user32.lib gdi32.lib])

Tested with the current cvs version.

Togl on Mac OS X

2004-11-05T02:32:01Z

Besides allowing Togl to build on Mac OS X, this build
also fixes some bugs in the Makefile. I'm not an OS X
expert, but these patches work for me.

Tested on OS X 10.3.5

Patches were made against current CVS as of today.

How the patch was made:
diff -Naur Togl-1.6 Togl-1.6.mac > mac_os_x.patch

How to apply the patch:
Make sure you're one directory below Togl-1.6.
patch -p0 <mac_os_x.patch

Happy hacking,
Tom

-setgrid support

2002-02-01T02:20:41Z

The enclosed patch added -setgrid support. The
difference from the text widget's setgrid is that the
argument is number of pixels per-grid unit. So
"-setgrid 1" would cause the window manager to report
the window size in pixels, "-setgrid 10" would cause
the window manager to report the window size in tens of
pixels. This patch could be extended to use different
grid units in the x and y directions (which is implicit
with the character size in the text widget), but that
will be for someone else to do. Note that some window
managers (dtwm) might report the wrong window size with
a grid unit of one pixel.

This patch includes code that limits calls to
Tk_ResizeWindow to when the width or height (or grid
size) actual changes, which removes extras redraws that
used to occur when only the cursor changes.

pixel format patch

2002-02-01T01:52:15Z

See previous patch description. For some reason
sourceforge did not upload the patch, so I'm trying
again.

arbitrary pixel format support

2002-02-01T00:55:34Z

The enclosed patch provides the ability to ask togl for
a particular pixel format (or visual in X-speak). This
is so one can use other criteria for choosing pixel
formats, such as wglChoosePixelFormat and
glXChooseFBConfig.

togl.c PostScript Fix

2002-02-01T00:48:45Z

The generateEPS function has illegal C code, i.e.,
multiple autoincrements without an intervening sequence
point. The enclosed patch fixes the bug (and removes
the associated compiler warnings from good compilers).
