Hi all,
I've built the OpenSceneGraph libraries and the osgviewerIPhone example for
arm7/arm7s and IOS 6.0 with XCode 4.5 using the instructions under "Generating
an iOS Xcode Project". The code was checked out from the SVN repository earlier
today. The data in Version (i haven't built osgversion) is:
#define OPENSCENEGRAPH_MAJOR_VERSION 3
#define OPENSCENEGRAPH_MINOR_VERSION 0
#define OPENSCENEGRAPH_PATCH_VERSION 1
#define OPENSCENEGRAPH_SOVERSION 80
Running it on an iPad 2 it throws some errors. Seems it is not comfortable with
ES 2.0:
++Before Converted source
void main()
{
gl_Position = ftransform();
gl_FrontColor = gl_Color;
}
++++++++
-------- Converted source
uniform mat4 osg_ModelViewProjectionMatrix;
attribute vec4 osg_Color;
attribute vec4 osg_Vertex;
void main()
{
gl_Position = osg_ModelViewProjectionMatrix * osg_Vertex;
gl_FrontColor = osg_Color;
}
----------------
Compiling VERTEX source:
1: uniform mat4 osg_ModelViewProjectionMatrix;
2: attribute vec4 osg_Color;
3: attribute vec4 osg_Vertex;
4:
5: void main()
6: {
7: gl_Position = osg_ModelViewProjectionMatrix * osg_Vertex;
8: gl_FrontColor = osg_Color;
9: }
VERTEX glCompileShader "" FAILED
VERTEX Shader "" infolog:
ERROR: 0:8: Use of undeclared identifier 'gl_FrontColor'
The code also attempts to load a 'hog.osg'. I've checked out
OpenSceneGraph-Data but don't find this file either here or in the source tree.
Tried copying 'cow.osg*' (seemed a fair trade :) into the bundle but so far I'm
getting:
FindFileInPath() : USING
/private/var/mobile/Applications/94D2B578-90DE-44D1-A900-99F343FAA028/osgviewerIPhone.app/cow.osg
No data loaded
Am i missing something? I'm just getting into the OSG source but thought
someone might be kind enough to save me some work. If there are any other
working IOS demos it would be appreciated too!
thanks
