示例1: Render
/// <summary>
/// Render to the provided instance of OpenGL.
/// </summary>
/// <param name="gl">The OpenGL instance.</param>
/// <param name="renderMode">The render mode.</param>
public override void Render(OpenGL gl, RenderMode renderMode)
{
// Create the evaluator.
gl.Map1(OpenGL.GL_MAP1_VERTEX_3,// Use and produce 3D points.
0, // Low order value of 'u'.
1, // High order value of 'u'.
3, // Size (bytes) of a control point.
ControlPoints.Width, // Order (i.e degree plus one).
ControlPoints.ToFloatArray()); // The control points.
// Enable the type of evaluator we wish to use.
gl.Enable(OpenGL.GL_MAP1_VERTEX_3);
// Beging drawing a line strip.
gl.Begin(OpenGL.GL_LINE_STRIP);
// Now draw it.
for (int i = 0; i <= segments; i++)
gl.EvalCoord1((float)i / segments);
gl.End();
// Draw the control points.
ControlPoints.Draw(gl, DrawControlPoints, DrawControlGrid);
}示例2: Draw
public override void Draw(OpenGL gl)
{
if(DoPreDraw(gl))
{
// Set our line settings.
lineSettings.Set(gl);
// Create the evaluator.
gl.Map1(OpenGL.MAP1_VERTEX_3,// Use and produce 3D points.
0, // Low order value of 'u'.
1, // High order value of 'u'.
3, // Size (bytes) of a control point.
controlPoints.Width, // Order (i.e degree plus one).
controlPoints.ToFloatArray()); // The control points.
// Enable the type of evaluator we wish to use.
gl.Enable(OpenGL.MAP1_VERTEX_3);
// Beging drawing a line strip.
gl.Begin(OpenGL.LINE_STRIP);
// Now draw it.
for(int i = 0; i <= segments; i++)
gl.EvalCoord1((float) i / segments);
gl.End();
// Draw the control points.
controlPoints.Draw(gl, drawPoints, drawLines);
// Restore the line attributes.
lineSettings.Restore(gl);
DoPostDraw(gl);
