Structure containing information about how to draw a part of a shape.

Note

Do not use this class directly, use DrawingInstructions returned by the various shape builder classes instead.

Member Data Documentation

GLuint oglplus::shapes::DrawOperation::phase

The phase of the drawing process.

The phase is a shape-builder-specific value that indicates which part of the shape is being rendered. Together with a "driver" function it can be used to change the shading program parameters (like the values of uniform variables) to switch the whole program or change GL state.

GLuint oglplus::shapes::DrawOperation::restart_index
