Member Function Documentation

void ome::qtwidgets::gl::Grid2D::create ( )
virtual

Create GL buffers.

Note
Requires a valid GL context. Must be called before rendering.

Referenced by ome::qtwidgets::GLView2D::initialize().

+ Here is the caller graph for this function:

virtual void ome::qtwidgets::gl::Grid2D::render ( const glm::mat4 &  mvp,
float  zoom 
)
pure virtual

Render the grid.

The zoom level is used to selectively draw gridlines of differing magnitude depending upon the magnification.

Parameters
mvpthe model view projection matrix.
zoomthe zoom level.

Implemented in ome::qtwidgets::gl::v20::Grid2D.

void ome::qtwidgets::gl::Grid2D::setSize ( const glm::vec2 &  xlim,
const glm::vec2 &  ylim 
)
protectedvirtual

Set the size of the x and y axes.

Parameters
xlimthe x axis limits (range).
ylimthe y axis limits (range).
