osg uniform变量传入ModelViewProjectionMatrix

the_mercury

请教高手，如何将model view projection matrix通过uniform 变量传入share中啊，我采用的shader版本是3.3，shader里面不再采用gl_ModelViewProjectionMatrix内置的uniform变量，请问有什么办法吗？


// vs
#version 330

layout(location = 0) in vec4 position;
uniform mat4 modelViewProjectionMatrix;

void main(void)
{
   gl_Position = modelViewProjectionMatrix * position;
}
