3D graphs (For example z = f(x, y), dynamic surfaces...)

Fxy

• Plotting a z=f(x, y) function using TGLHeightField
• using TGLXYZGrid as a graph grid.
• 

• CVS/Demos/graph/fxy

Heightfield

• A more advanced use for TGLHeightField (resolution changes, color, lighting...)
• using TGLHeightField to plot a dynamic f(x, y) function
• 

• CVS/Demos/graph/heightfield

Points

• Rendering clouds of points with TGLPoints:
• Demonstrates point paramaters
• 

• CVS/Demos/graph/points

Projection

• Connecting graph points to their projection plane and
• using parallel projection matrices.
• Includes blending direct OpenGL (using TGLDirectOpenGL) with other scene objects
• 

• CVS/Demos/graph/projection

Splines

• Shows TGLLines using cubic spline mode.
• Basic spline use with color interpolation
• using the camera in orthogonal mode for rendering 2D graphs
