Re: [osg-users] [build] CMake can not find include files
If you're generating the cmake file through the cmake application then it should be generated in your build folder. If you are using cmake on the command line then you will need to pass cmake -G "Visual Studio XX" to the command line, where XX is your Visual Studio version.

Re: [osg-users] [build] CMake can not find include files
Hi, it seems my fault was to look into the "src" directory for the sources. With the cmakelists.txt file in the base directory openscenegraph cmake worked succesfully. Now it is only to find out how to find the project file for VC++ which might load the project into the IDE? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=73934#73934 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [build] CMake can not find include files
Hi Sam, i do not have any binaries so i don't see any way to set a path to it? I am trying to build binaries and my hope was the delivered cmakelists.txt would be the key for this. As Robert pointed out the cmakelists.txt file in the src/osg directory should do the job but it spits the weird error that a cmake command is unknown to cmake.

Hi Robert,
this is exactly the one i am referreing to and it is the one that spits out the
error because of its last line saying :
SETUP_LIBRARY(${LIB_NAME})
How can a Cmake command be the cause for an error like this?
unknown cmake command

Hi Peter, Not sure how you're attempting to compile OSG but I'd recommend you'd do the following: [image: osg1.png] >From here I would hit Configure and then Generate. Open up the ALL_BUILD project and right-click OpenThreads and hit build. This will ensure all the dependencies are in place.

Re: [osg-users] TriangleStrip mesh is not smooth...
Hi,
Thank you Robert...
Here is how I create the mesh:
float column_x_loc = -(LAND_WIDTH * LAND_TRIANGLE_WIDTH)/2;
float column_z_loc = -(LAND_DEPTH * LAND_TRIANGLE_DEPTH)/2
float column_y_loc = DETAIL_TERRAIN_FLOOR;
for (int c = 0;c < LAND_WIDTH;c++)
{
for (int r = 0; r < LAND_DEPTH;r++)
{
(*terrain)[thisIndex][0] = column_x_loc;
(*terrain)[thisIndex][1] = column_z_loc;
(*terrain)[thisIndex][2] = column_y_loc;
(*terrain_colors)[thisIndex][0] = 46.0f/256.0f;
(*terrain_colors)[thisIndex][1] = 76.0f/256.0f;
(*terrain_colors)[thisIndex][2] =
100.0f/256.0f;
(*terrain_colors)[thisIndex][3] = 0.3f;
column_z_loc += LAND_TRIANGLE_DEPTH;
thisIndex++;
}
}
On an update I move all of the rows back one and replace the 1 row with new
data.
I use a transparent_weight value to have older data disappear as it is updated.
float transparent_weight = 1.0;
float transparent_adjustment = 0.02;
for (int r = 0; r < LAND_DEPTH - 1; r++)
{
transparent_weight = 0.1;
for (int c = 1;c < 50; c++)
{
col_index = (c * LAND_WIDTH);
(*terrain)[col_index + r][2] =
(*terrain)[col_index + r + LAND_WIDTH][2];
(*terrain_colors)[col_index + r][0] =
(*terrain_colors)[col_index + r + LAND_WIDTH][0];
(*terrain_colors)[col_index + r][1] =
(*terrain_colors)[col_index + r + LAND_WIDTH][1];
(*terrain_colors)[col_index + r][2] =
(*terrain_colors)[col_index + r + LAND_WIDTH][2];
(*terrain_colors)[col_index + r][3] =
transparent_weight;//(*terrain_colors)[col_index + r + LAND_WIDTH][3];
transparent_weight +=
transparent_adjustment;
}
}
The data at the first row is always smooth. I get missing triangles only in
the middle or rear of the terrain.
Any suggestions are welcome. I have the program working the way I want if I
can get this mesh problem solved.
Thank you again!
Cheers,
Mike

Re: [osg-users] TriangleStrip mesh is not smooth...
Hi Mike, You don't provide any details about how you've created the mesh, whether you've loaded it from some loader, you've use some util from the OSG or other 3rd party tool or done it by hand yourself. Given we know nothing about how you've created the mesh there isn't much can do to help advice how to resolve the issues. Robert.

I have tried the test program against the OpenSceneGraph-3.4 branch
and it behaves the same for all command line options. This doesn't
tell us much other than that there is regression between 3.4 and 3.6.
I haven't tried master yet.

I have built the example, and to help with test have changed the
#ifdef blocks to ones that check arguments.read("--ro") for the
RealizerOperation usage and "--reset" for the
resetVertexAttributeAlias. Attached is the modified file.
If you run the test with --ro and have it use the custom
RealizerOperation I see a completely red cessna. If I used --ro and
--reset I see multi-colour (blue, red etc) one, if I run without any
options I see the multi-colour one.
I don't see any command line warnings though. I'm testing under
Kubuntu with OSG-3.6 branch, my drive info is:
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce GTX 760/PCIe/SSE2
OpenGL core profile version string: 4.5.0 NVIDIA 384.111
OpenGL core profile shading language version string: 4.50 NVIDIA
I don't yet have any idea what is going wrong, it's obviously very odd
that the custom RealizeOperation is having an effect when it does
nothing itself.
Before I start diving deeper I'd like to know what others are seeing
with these different combinations and if any errors are being printed
in the console, if so what are they. Also let us know the OSG version
and driver/OS details.
Robert.
