I am trying to use a trivial geometry shader but when run in Shader Builder on a laptop with a GMA X3100 it falls back and uses the software render. According this document the GMA X3100 does support EXT_geometry_shader4.
The input is POINTS and the output is LINE_STRIP.
What would be required to get it to run on the GPU (if possible)
uniform vec2 offset;
void main()
{
gl_Position = gl_PositionIn[0];
EmitVertex();
gl_Position = gl_PositionIn[0] + vec4(offset.x,offset.y,0,0);
EmitVertex();
EndPrimitive();
}
